Design Capital And Design Moves: The Logic Of Digital Business Strategy, C. Jason Woodard, Narayan Ramasubbu, F. Ted Tschang, V. Sambamurthy Jun 2013

Design Capital And Design Moves: The Logic Of Digital Business Strategy, C. Jason Woodard, Narayan Ramasubbu, F. Ted Tschang, V. Sambamurthy

Research Collection Lee Kong Chian School Of Business

As information technology becomes integral to the products and services in a growing range of industries, there has been a corresponding surge of interest in understanding how firms can effectively formulate and execute digital business strategies. This fusion of IT within the business environment gives rise to a strategic tension between investing in digital artifacts for long-term value creation and exploiting them for short-term value appropriation. Further, relentless innovation and competitive pressures dictate that firms continually adapt these artifacts to changing market and technological conditions, but sustained profitability requires scalable architectures that can serve a large customer base and stable …

Shackling Short Sellers: The 2008 Shorting Ban, Ekkehart Boehmer, Charles M. Jones, Xiaoyan Zhang Jun 2013

Shackling Short Sellers: The 2008 Shorting Ban, Ekkehart Boehmer, Charles M. Jones, Xiaoyan Zhang

Research Collection Lee Kong Chian School Of Business

In September 2008, the U.S. Securities and Exchange Commission (SEC) temporarily banned most short sales in nearly 1,000 financial stocks. We examine the ban's effect on market quality, shorting activity, the aggressiveness of short sellers, and stock prices. The ban's effects are concentrated in larger stocks; there is little effect on firms in the lower half of the size distribution. Although shorting activity drops by about 77% in large-cap stocks, stock prices appear unaffected by the ban. All but the smallest quartile of firms subject to the ban suffer a severe degradation in market quality.

On The Derivation Of Estimators Of Foster-Greer-Thorbecke (Fgt) Poverty Indices, Oyedeji I. Osowole, Adebayo T. Bamiduro Jun 2013

On The Derivation Of Estimators Of Foster-Greer-Thorbecke (Fgt) Poverty Indices, Oyedeji I. Osowole, Adebayo T. Bamiduro

CBN Journal of Applied Statistics (JAS)

Poverty analysis has relied heavily on data in summarized form and this has created dearth of knowledge on the statistical properties of Foster-Greer-Thorbecke (FGT) poverty indices. This study derived estimators of FGT poverty indices from first principles in an attempt to provide an insight into some intrinsic characteristics of FGT indices. The estimators are found to be reasonably unbiased and consistent. The estimates of the indices obtained from the estimators are approximately 53%, 22% and 12% for the head count, poverty gap and square poverty gap indices. From the conventional method, the estimates are approximately 52%, 21% and 11% respectively. …

Measuring Technical Efficiency Of Wireless And Wired Technologies In Nigeria Cyber Cafés, Sule Magaji, Eke I. Chukwuemeka Jun 2013

Measuring Technical Efficiency Of Wireless And Wired Technologies In Nigeria Cyber Cafés, Sule Magaji, Eke I. Chukwuemeka

CBN Journal of Applied Statistics (JAS)

This study examined the technical efficiency (TE) of two different remote internet access methods, wireless and wired in Nigeria using the stochastic frontier production function analysis. Primary data were obtained through the use of a set of questionnaire from four hundred and fifty representative samples of cyber café operators. The results show that in Nigeria, in spite of the acclaimed superiority of wireless technologies internationally, wired technology (within the context of Nigeria’s socio-economic constraints) is (still) more efficient technically with mean technical efficient indices of 0.914 and 0.797 respectively. The analysis also suggests that age and years of education of …

Monetary Policy Rule: A Broad Monetary Conditions Index For Nigeria, Yaaba N. Baba Jun 2013

Monetary Policy Rule: A Broad Monetary Conditions Index For Nigeria, Yaaba N. Baba

CBN Journal of Applied Statistics (JAS)

To determine the relative importance of both the domestic and external influences on monetary policy formulation, this paper constructs a broad monetary conditions index for Nigeria. It brings together the three key channels of monetary transmission, namely interest rate, exchange rate and credit channels. The result gives dominance to exchange rate channel, followed by credit channel and interest rate channel. The resultant monetary conditions index traces fairly well the policy direction of the Central Bank of Nigeria for the studied period, hence can serve as an adequate gauge of monetary policy stance of the Bank.

Effect Of Monetary-Fiscal Policies Interaction On Price And Output Growth In Nigeria, Musa Yakubu, Asar K. Barfour, Shehu U. Gulumbe Jun 2013

Effect Of Monetary-Fiscal Policies Interaction On Price And Output Growth In Nigeria, Musa Yakubu, Asar K. Barfour, Shehu U. Gulumbe

CBN Journal of Applied Statistics (JAS)

This paper investigates the effectiveness of monetary-fiscal policies interaction on price and output growth in Nigeria. The dynamic correlations of variables have been captured by the analyses of impulse response and variance decomposition. From innovation analyses, the results suggest that the policy variables money supply and government revenue have more positive impact on price and economic growth in Nigeria specifically in the long run, thus some time with lag. Although monetary and fiscal policy variables have a dominant effect on economic activity, it is clear from this study that economic activity is dominated by its own dynamics in most of …

The Relationship Between Domestic Savings And Investment: The Feldstein-Horioka Test Using Nigerian Data, Inuwa Nasiru, Usman M. Haruna Jun 2013

The Relationship Between Domestic Savings And Investment: The Feldstein-Horioka Test Using Nigerian Data, Inuwa Nasiru, Usman M. Haruna

CBN Journal of Applied Statistics (JAS)

This study explores the relationship between savings and investment in Nigeria during the period 1980-2011. Unlike previous studies, this study employed Autoregressive Distributed Lag (ARDL) Bounds testing approach to test for long run relationship. The short-run dynamics are also captured from error correction model (ECM).The results of the Bounds test suggest that there is a long run relationship between savings and investment. This result is consistent with a number of earlier studies reviewed in the literature that found saving and investment to be cointegrated in the long run. The results also support the Feldstein-Horioka (1980) hypothesis that postulates low capital …

Exchange–Rates Volatility In Nigeria: Application Of Garch Models With Exogenous Break, Bala A. Dahiru, Joseph O. Asemota Jun 2013

Exchange–Rates Volatility In Nigeria: Application Of Garch Models With Exogenous Break, Bala A. Dahiru, Joseph O. Asemota

CBN Journal of Applied Statistics (JAS)

This paper examines exchange–rate volatility with GARCH models using monthly exchange–rate return series from 1985:1 to 2011:7 for Naira/US dollar return and from 2004:1 to 2011:7 for Naira/British Pounds and Naira/Euro returns. The study compare estimates of variants of GARCH models with break in respect of the US dollar rates with exogenously determined break points. Our results reveal presence of volatility in the three currencies and equally indicate that most of the asymmetric models rejected the existence of a leverage effect except for models with volatility break. Evaluating the models through standard information criteria, volatility persistence and the log likelihood …

The Role Of Central Bank Of Nigeria’S Analytical Balance Sheet And Monetary Survey In Monetary Policy Implementation, Sani I. Doguwa, Sunday N. Essien Jun 2013

The Role Of Central Bank Of Nigeria’S Analytical Balance Sheet And Monetary Survey In Monetary Policy Implementation, Sani I. Doguwa, Sunday N. Essien

CBN Journal of Applied Statistics (JAS)

This paper discusses the significance of Central Bank of Nigeria’s (CBN) monetary aggregates in the implementation of monetary policy. The Analytical Balance Sheet and monetary survey are shown to be useful tools in the analysis of monetary and credit developments in the economy. It also discusses the role of the aggregates in monetary policy implementation through the adjusted money multiplier, which explains how policy actions of the CBN influence the broad money supply. Finally, the paper attempts to estimate the Taylor-type monetary policy reaction function for Nigeria using the monetary policy rate and reserve money since December 2006 when the …

Adaptive Credit Scoring With Analytic Hierarchy Process, Kwang Yong Koh, Murphy Choy, Michelle L. F. Cheong Jun 2013

Adaptive Credit Scoring With Analytic Hierarchy Process, Kwang Yong Koh, Murphy Choy, Michelle L. F. Cheong

Research Collection School Of Computing and Information Systems

Credit risk assessment for consumers has been a cornerstone of risk management in financial institutions and constitutes a component of the three pillars of Basel II. Traditionally, the concept of 5 ‘C’s was widely adopted by financial institutions as the key basis for credit risk assessment for loan applications by prospective borrowers. With the evolution of the credit risk management practices, more quantitative methods such as credit scorecards have been developed, which is implemented through the use of logistic regression, decision trees and neural networks. However, such approaches proved to be inadequate with the validity and effectiveness of the approaches …

Cameo: A Middleware For Mobile Advertisement Delivery, Azeem J. Khan, Kasthuri Jayarajah, Dongsu Han, Archan Misra, Rajesh Krishna Balan, Srinivasan Seshan

Research Collection School Of Computing and Information Systems

Advertisements are the de-facto currency of the Internet with many popular applications (e.g. Angry Birds) and online services (e.g., YouTube) relying on advertisement generated revenue. However, the current economic models and mechanisms for mobile advertising are fundamentally not sustainable and far from ideal. In particular, as we show, applications which use mobile advertising are capable of using significant amounts of a mobile users' critical resources without being controlled or held accountable. This paper seeks to redress this situation by enabling advertisement supported applications to become significantly more "user-friendly". To this end, we present the design and implementation of CAMEO, a …

Linking Distributive And Procedural Justice To Employee Engagement Through Social Exchange: A Field Study In India, Soumendu Biswas, Arup Varma, Aarti Ramaswami Jun 2013

Linking Distributive And Procedural Justice To Employee Engagement Through Social Exchange: A Field Study In India, Soumendu Biswas, Arup Varma, Aarti Ramaswami

School of Business: Faculty Publications and Other Works

Research linking justice perceptions to employee outcomes has referred to social exchange as its central theoretical premise. We tested a conceptual model linking distributive and procedural justice to employee engagement through social exchange mediators, namely, perceived organizational support and psychological contract, among 238 managers and executives from manufacturing and service sector firms in India. Findings suggest that perceived organizational support mediated the relationship between distributive justice and employee engagement, and both perceived organizational support and psychological contract mediated the relationship between procedural justice and employee engagement. Theoretical and practical implications with respect to organizational functions are discussed.

Stock Picking, Industry Picking And Market Timing In Sell-Side Research, Ohad Kadan, Leonardo Madureira, Rong Wang, Tzachi Zach Jun 2013

Stock Picking, Industry Picking And Market Timing In Sell-Side Research, Ohad Kadan, Leonardo Madureira, Rong Wang, Tzachi Zach

Research Collection Lee Kong Chian School Of Business

Sell-side analysts employ different benchmarks when defining their stock recommendations. For example, a ‘buy’ for some brokers means the stock is expected to outperform its peers in the same sector (“industry benchmarkers”), while for other brokers it means the stock is expected to outperform the market (“market benchmarkers”), or just some absolute return (“total benchmarkers”). We use these benchmarks to analyze the role of stock picking, industry picking and market timing in contributing to the performance of stock recommendations. We are able to do so given that different benchmarks suggest the use of different sets of abilities. Analysis of the …

The Influence Of Mindful Attention On Value Claiming In Distributive Negotiations: Evidence From Four Laboratory Experiments, Jochen Reb, Jayanth Narayanan Jun 2013

The Influence Of Mindful Attention On Value Claiming In Distributive Negotiations: Evidence From Four Laboratory Experiments, Jochen Reb, Jayanth Narayanan

Research Collection Lee Kong Chian School Of Business

We examined the effect of mindful attention on negotiation outcomes in distributive negotiations across four experiments. In Studies 1 and 2, participants who performed a short mindful attention exercise prior to the negotiation claimed a larger share of the bargaining zone than the control condition participants they negotiated with. Study 3 replicated this finding using a different manipulation of mindful attention. Study 4 again replicated this result and also found that mindful negotiators were more satisfied with both the outcome and the process of the negotiation. We discuss theoretical and practical implications, limitations, and future directions.

Which Board Interlocks Matter? The Impact Of Managerial Power, Legitimacy, And Family Power On The Adoption Of Stock Option Pay, Toru Yoshikawa, Jung Wook Shim, A. Tuschke Jun 2013

Which Board Interlocks Matter? The Impact Of Managerial Power, Legitimacy, And Family Power On The Adoption Of Stock Option Pay, Toru Yoshikawa, Jung Wook Shim, A. Tuschke

Research Collection Lee Kong Chian School Of Business

Inter-organizational relationships and the networks they create are an important mechanism for the transfer of knowledge and learning. Network ties enable the transfer of experiential knowledge – for instance of vicarious information through board interlocks. While we know that organizational learning occurs and is influenced by factors like the strength of ties and a firm’s position in the network, it is still unclear what causes the firm to act on the information gained through network ties. We build on prior studies on the impact of interlocking board ties ion the adoption of new practices and analyze the effects of different …

Accounting Restatements And External Financing Choices, Xia Chen, Qiang Cheng, Alvis Lo Jun 2013

Accounting Restatements And External Financing Choices, Xia Chen, Qiang Cheng, Alvis Lo

Research Collection School Of Accountancy

There is little research on how accounting information quality affects a firm’s external financing choices. In this paper, we use the occurrence of accounting restatements as a proxy for the reduced credibility of accounting information and investigate how restatements affect a firm’s external financing choices. We find that for firms that obtain external financing after restatements, they rely more on debt financing, especially private debt financing, and less on equity financing. The increase in debt financing is more pronounced for firms with more severe information problems and less pronounced for firms with prompt CEO/CFO turnover and auditor dismissal. Our evidence …

Collaborative Benefits And Coordination Costs: Learning And Capability Development In Science, M. Onal Vural, Linus Dahlander, Gerard George Jun 2013

Collaborative Benefits And Coordination Costs: Learning And Capability Development In Science, M. Onal Vural, Linus Dahlander, Gerard George

Research Collection Lee Kong Chian School Of Business

We examine the effects of team structure and experience on the impact of inventions produced by scientific teams. Whereas multidisciplinary, collaborative teams have become the norm in scientific production, there are coordination costs commensurate with managing such teams. We use patent citation analysis to examine the effect of prior collaboration and patenting experience on invention impact of 282 patents granted in human embryonic stem cell (hESC) research from 1998 to 2010. Our results reveal that team experience outside the domain may be detrimental to project performance in a setting where the underlying knowledge changes. In stem cell science, we show …

Are Investors' Corporate Site Visits Informative?, Qiang Cheng, Fei Du, Xin Wang, Yutao Wang Jun 2013

Are Investors' Corporate Site Visits Informative?, Qiang Cheng, Fei Du, Xin Wang, Yutao Wang

Research Collection School Of Accountancy

Corporate site visit is an important type of investors’ information acquisition activities, but its usefulness is not well understood in the literature, partially due to the lack of data. Using a unique dataset of corporate site visits in China, we analyze the information content and the determinants of corporate site visits. Our main findings are as follows. First, we document a significant market reaction to corporate site visits and the market reaction is stronger for group visits, for visits conducted by mutual fund managers, for visits covering firm-specific topics, and for firms with poorer information environment. Second, we find that …

Examining The Informational Role Of Analysts’ Forecasts And Its Impact On The Relation Between Earnings Surprises And Investors’ Responses, Joonho Lee, Kevin Ow Yong, Clement Michael Jun 2013

Examining The Informational Role Of Analysts’ Forecasts And Its Impact On The Relation Between Earnings Surprises And Investors’ Responses, Joonho Lee, Kevin Ow Yong, Clement Michael

Research Collection School Of Accountancy

Prior research documents the existence of two distinct post-earnings-announcement-drifts. Interestingly, investors seem to underreact more toward analyst-based earnings surprises than toward seasonal random walk earnings surprises. In this paper, we measure the extent of investors’ delayed reaction relative to the total market response to the earnings surprises. Using this measure, we find that investors react proportionately faster and more thoroughly to analyst-based earnings surprises than to random walk earnings surprises, suggesting that analyst-based earnings surprises are relatively less related with a delayed investor reaction compared with random walk earnings surprises. We also find that as the informativeness of analyst earnings …

Affect As A Decision-Making System Of The Present, Hannah H. Chang, Michel Tuan Pham Jun 2013

Affect As A Decision-Making System Of The Present, Hannah H. Chang, Michel Tuan Pham

Research Collection Lee Kong Chian School Of Business

We review a variety of empirical findings consistent with the general thesis that the affective system of judgment and decision making is inherently anchored in the present. Building on this thesis, we advance the specific hypothesis that affective feelings are relied upon more (weighted more heavily) in judgments whose outcomes and targets are closer to the present than in those whose outcomes and targets are temporally more distant. Consistent with this hypothesis, results from five experiments show that temporal proximity (a) amplifies the relative preference for options that are affectively superior, and (b) increases the effects of incidental affect on …

Architectural Control And Value Migration In Layered Ecosystems: The Case Of Open-Source Cloud Management Platforms, Richard Tee, C. Jason Woodard Jun 2013

Architectural Control And Value Migration In Layered Ecosystems: The Case Of Open-Source Cloud Management Platforms, Richard Tee, C. Jason Woodard

Research Collection School Of Computing and Information Systems

Our paper focuses on strategic decision making in layered business ecosystems, highlighting the role of cross-layer interactions in shaping choices about product design and platform governance. Based on evidence from the cloud computing ecosystem, we analyze how concerns about architectural control and expectations regarding future value migration influence the design of product interfaces and the degree of openness to external contributions. We draw on qualitative longitudinal data to trace the development of two open-source platforms for managing cloudbased computing resources. We focus in particular on the emergence of a layered "stack" in which these platforms must compete with both vertically …

When Do Consumers Purchase Online?: Based On Inter-Purchase Time, Youngsoo Kim Jun 2013

When Do Consumers Purchase Online?: Based On Inter-Purchase Time, Youngsoo Kim

Research Collection School Of Computing and Information Systems

This study is motivated by the premise that online consumers can make a purchase at any time of day if they have even a tiny time slot along with Internet access. To identify the increased shopping time flexibility, we first characterize the patterns of online purchase timing in comparison to those in the offline market. The results show (1) the breakdown of purchase timing regularity and (2) the change of weekly spike purchase occurrence. Second, we build online inter-purchase time model and estimate it with the data collected from one of the premier online vendors in Korea. We verify new …
