Efficient Estimation Of Average Derivatives In Npiv Models: Simulation Comparisons Of Neural Network Estimators, Jiafeng Chen, Xiaohong Chen, Elie Tamer

Cowles Foundation Discussion Papers

Artificial Neural Networks (ANNs) can be viewed as \emph{nonlinear sieves} that can approximate complex functions of high dimensional variables more effectively than linear sieves. We investigate the computational performance of various ANNs in nonparametric instrumental variables (NPIV) models of moderately high dimensional covariates that are relevant to empirical economics. We present two efficient procedures for estimation and inference on a weighted average derivative (WAD): an orthogonalized plug-in with optimally-weighted sieve minimum distance (OP-OSMD) procedure and a sieve efficient score (ES) procedure. Both estimators for WAD use ANN sieves to approximate the unknown NPIV function and are root-n asymptotically normal …

Linguistic Variation From Cognitive Variability: The Case Of English 'Have', Muye Zhang

Linguistics Graduate Dissertations

In this dissertation, I seek to construct a model of meaning variation built upon variability in linguistic structure, conceptual structure, and cognitive makeup, and in doing so, exemplify an approach to studying meaning that is both linguistically principled and neuropsychologically grounded. As my test case, I make use of the English lexical item ‘have' by proposing a novel analysis of its meaning based on its well-described variability in English and its embed- ding into crosslinguistically consistent patterns of variation and change.

I support this analysis by investigating its real-time comprehension patterns through behavioral, electropsychophysiological, and hemodynamic brain data, thereby incorporating …

The Effect Of A Financial Crisis On Household Finances: A Case Study Of Iceland’S Financial Crisis, Axel Hall, Andri S. Scheving, Gylfi Zoega

Journal of Financial Crises

Iceland experienced a financial crisis in 2008–2009 when its banking system collapsed, the currency lost half its value, most businesses became technically insolvent, house prices fell, and household debt increased due to indexation to foreign currencies or the price level. This paper tells the story of the crisis and maps the losses to households using a dataset from tax returns that includes all taxpayers in the country and contains the value of housing, mortgage debt, disposable income, and net worth. For relative losses in net worth, the results show that families with children, especially those with parents aged between 24 …

A Game-Theoretic Analysis Of Childhood Vaccination Behavior: Nash Versus Kant, Philippe De Donder, Humberto Llavador, Stefan Penczynski, John E. Roemer, Roberto Vélez

Cowles Foundation Discussion Papers

Whether or not to vaccinate one’s child is a decision that a parent may approach in several ways. The vaccination game, in which parents must choose whether to vaccinate a child against a disease, is one with positive externalities (herd immunity). In some societies, not vaccinating is an increasingly prevalent behavior, due to deleterious side effects that parents believe may accompany vaccination. The standard game-theoretic approach assumes that parents make decisions according to the Nash behavioral protocol, which is individualistic and non-cooperative. Because of the positive externality that each child’s vaccination generates for others, the Nash equilibrium suffers from a …

“Quietly Incomplete”: Academic Historians, Digital Archival Collections, And Historical Research In The Web Era, Donald Force, Bradley Wiles

Journal of Contemporary Archival Studies

Since the early 1990s, archives institutions largely have approached digital archival collections with an “if we build it, they will come” mentality. But the extent and motivations of use for traditional and emerging patron groups are constantly evolving, and the factors or conditions that characterize use vary wildly in the web environment. As part of a broader study investigating how academic historians utilize and interact with digital archival collections, this paper details the findings of a pilot project involving a citation analysis, survey, and semi-structured interviews with academic historians from a medium-sized Carnegie Research 1 university. This limited exploratory study …

The Us-China Trade War And Global Reallocations, Pablo Fajgelbaum, Pinelopi Goldberg, Patrick Kennedy, Amit Khandelwal, Daria Taglioni

Discussion Papers

We study global trade responses to the US-China trade war. We estimate the tariff impacts on product-level exports to the US, China, and rest of world. On average, countries decreased exports to China and increased exports to the US and rest of world. Most countries export products that complement the US and substitute China, and a subset operate along downward-sloping supplies. Heterogeneity in responses, rather than specialization, drives export variation across countries. Surprisingly, global trade increased in the products targeted by tariffs. Thus, despite ending the trend towards tariff reductions, the trade war did not halt global trade growth.

Aggregate Implications Of Barriers To Female Entrepreneurship, Gaurav Chiplunkar, Pinelopi K. Goldberg

Discussion Papers

We develop a framework for quantifying barriers to labor force participation (LFP) and entrepreneurship faced by women in developing countries, and apply it to the Indian economy. We find that women face substantial barriers to LFP. The costs for expanding businesses through the hiring of workers are also substantially higher for women entrepreneurs. However, there is one area in which female entrepreneurs have an advantage: the hiring of female workers. We show that this is not driven by the sectoral composition of female employment. Consistent with this pattern, we find even without promoting female LFP, policies that boost female entrepreneurship …

The Measuring Of Assortativeness In Marriage, Pierre-André Chiappori, Monica Costa-Dias, Costas Meghir

Cowles Foundation Discussion Papers

Measuring the extent to which assortative matching
differs between two economies is challenging when the marginal distributions of the characteristic along which sorting takes place (e.g. education) also changes for either or both sexes. Drawing from the statistics literature we define simple conditions that any index has to satisfy to provide a measure of change in sorting that is not distorted by changes in the marginal distributions of the characteristic. While our characterisation of indices of assortativeness is not complete, and hence cannot exclude the possibility of multiple indices providing contradictory results, in an empirical application to US data we …

A Structural Model Of Organizational Buying For B2b Markets: Innovation Adoption With Share Of Wallet Contracts, Navid Mojir, K. Sudhir

Cowles Foundation Discussion Papers

The paper develops the first structural model of organizational buying to study innovation diffusion in a B2B market. Our model is particularly applicable for routinized exchange relationships, whereby centralized buyers periodically evaluate and choose contracts, then downstream users or- der items on contracted terms. The model captures different utility tradeoffs for users and buyers while accounting for how buyer and user choices interact to impact user adoption/usage and buyer contracting. Further, the paper considers the dynamics induced by share of wallet (SOW) pricing contracts, commonly used in B2B markets to reward customer loyalty with discounts for buying more than a …

Incorporating Search And Sales Information In Demand Estimation, Ali Hortaçsu, Olivia R. Natan, Hayden Parsley, Timothy Schwieg, Kevin R. Williams

Cowles Foundation Discussion Papers

We propose an approach to modeling and estimating discrete choice demand that allows for a large number of zero sale observations, rich unobserved heterogeneity, and endogenous prices. We do so by modeling small market sizes through Poisson arrivals. Each of these arriving consumers then solves a standard discrete choice problem. We present a Bayesian IV estimation approach that addresses sampling error in product shares and scales well to rich data environments. The data requirements are traditional market-level data and measures of consumer search intensity. After presenting simulation studies, we consider an empirical application of air travel demand where product-level sales …

Endogenous Spatial Production Networks: Quantitative Implications For Trade & Productivity, Piyush Panigrahi

Cowles Foundation Discussion Papers

Larger Indian firms selling inputs to other firms tend to have more customers, tend to be used more intensively by their customers, and tend to have larger customers. Motivated by these regularities, I propose a novel empirical model of trade featuring endogenous formation of input-output linkages between spatially distant firms. The empirical model consists of (a) a theoretical framework that accommodates first order features of firm-to-firm network data, (b) a maximum likelihood framework for structural estimation that is uninhibited by the scale of data, and (c) a procedure for counterfactual analysis that speaks to the effects of micro- and macro- …

Organizational Structure And Pricing: Evidence From A Large U.S. Airline, Ali Hortaçsu, Olivia R. Natan, Hayden Parsley, Timothy Schwieg, Kevin R. Williams

Cowles Foundation Discussion Papers

We study how organizational boundaries affect pricing decisions using comprehensive data from a large U.S. airline. We document that the firm’s advanced pricing algorithm, utilizing inputs from different organizational teams, is subject to multiple biases. To quantify the impacts of these biases, we estimate a structural demand model using sales and search data. We recover the demand curves the firm believes it faces using forecasting data. In counterfactuals, we show that correcting biases introduced by organizational teams individually have little impact on market outcomes, but coordinating organizational outcomes leads to higher prices/revenues and increased deadweight loss in the markets studied.

The Us Supervisory Capital Assessment Program (Scap) And Capital Assistance Program (Cap), Aidan Lawson

Journal of Financial Crises

Due to continued stress during the Global Financial Crisis, the US Treasury released a series of additional measures in February 2009 that included a mandatory stress test for major U.S. bank holding companies (BHCs), backed by government capital. The stress test, known as the Supervisory Capital Assessment Program (SCAP), tested the capital adequacy of the 19 U.S. BHCs that had more than $100 billion in assets. A large interagency team of regulators and other experts estimated losses and income under two hypothetical scenarios for the group of BHCs: a baseline that reflected the consensus belief about the course of the …

Us Capital Purchase Program, Aidan Lawson, Adam Kulam

Journal of Financial Crises

During the fall of 2008, the US government was faced with a financial crisis of unprecedented scope. Having already exercised the authority to put Fannie Mae and Freddie Mac into conservatorship in September, the stage was set for the US government to intervene more broadly in strained financial markets. This intervention would ultimately come in the form of the Emergency Economic Stabilization Act of 2008 (EESA), which was passed on October 3, 2008. The main provision of EESA was the Troubled Asset Relief Program, or TARP, a $700 billion program initially designed to purchase troubled assets off the balance sheets …

Us Community Development Capital Initiative (Cdci), Adam Kulam

Journal of Financial Crises

The United States Department of the Treasury responded to the Global Financial Crisis with an economy-wide stimulus package called the Troubled Assets Relief Program (TARP). Within the portion of TARP’s budget dedicated to bank investments, about $570.1 million was disbursed to community development financial institutions (CDFIs)—specifically, banks and credit unions (depositories)—in a program called the Community Development Capital Initiative (CDCI). Through the CDCI, Treasury provided capital to CDFI depositories, encouraged them to lend to small businesses, and promoted other community-oriented goals. The CDFI depositories issued either preferred shares or unsecured subordinated debentures to Treasury at low (2%) interest rates for …

Us Reconstruction Finance Corporation: Preferred Stock Purchase Program, Aidan Lawson

Journal of Financial Crises

By March 1933, the early collateralized lending programs of the Reconstruction Finance Corporation (RFC) had failed to prevent the recurrence of bank runs and panic in US financial markets. These conditions forced newly elected President Franklin Delano Roosevelt to call for a nationwide bank holiday from March 6 to March 9. On the final day of the holiday, a special session of Congress passed the Emergency Banking Act (EBA), which gave the RFC the power to make investments via preferred equity of distressed institutions. Under the EBA, the RFC could subscribe to and make loans on cumulative non-assessable preferred stock …

Uk Bank Recapitalisation Scheme, Alec Buchholtz

Journal of Financial Crises

Following the collapse of Lehman Brothers and the ensuing global credit crunch in late 2008, Her Majesty’s Treasury (HMT) announced a large economic package to provide support to the UK banking sector. As part of the package, the eight largest banks committed themselves to raising their total Tier 1 capital by £25 billion through either private fundraising or government assistance. Thus, the economic package featured a new Bank Recapitalisation Scheme to invest up to £50 billion in capital into UK banking and credit institutions that could not raise their assets in the private sector. Government capital was invested into either …

Turkey Saving Deposit Insurance Fund Bank Recapitalization (2000–2001), Natalie Leonard

Journal of Financial Crises

Throughout the 1990s, Turkey’s macroeconomy featured high and fluctuating inflation and oscillating GDP growth rates. After Turkey’s April 1999 elections, Turkey adopted a new economic program in coordination with the International Monetary Fund (IMF) with three goals: fiscal adjustment, structural reform, and an exchange rate commitment. By the end of the third quarter of 2000, concerns over the pace of structural reform mounted and short-term interest rates remained high. The new Banking Regulation and Supervision Agency (BRSA) revealed significant corruption within several small banks taken over by the Saving Deposit Insurance Fund (SDIF). In November 2000, Demirbank, a private bank …

Thailand Capital Support Facilities 1998, Adam Kulam

Journal of Financial Crises

After the floatation of the baht on July 2, 1997, the Thai economy endured a financial crisis from massive currency devaluation, exchange rate losses, and non-performing loans (NPLs). In response, the Thai government employed two types of restructuring programs: (1) the alleviation of NPLs and distressed assets, (2) the correction of financial institution insolvency and capital inadequacy. To help recapitalize private institutions with public funds, the government introduced tier-1 and tier-2 capital support facilities. The tier-1 facility aimed to attract private capital, and the tier-2 facility aimed to stimulate lending and corporate debt restructuring. Capital injections took the form of …

Sweden 1991 Bank Support Authority (Bankstödsnämnden), Natalie Leonard

Journal of Financial Crises

Sweden’s economic downturn and growing unemployment in the early 1990s led to increased uncertainty about banks’ risks. Turbulence in foreign exchange markets and speculation against the Swedish krona caused significant problems in the housing paper market. The ensuing banking crisis affected six of the seven largest Swedish banks. Loan losses peaked in 1992 at nearly SEK 80 billion while the banking sector recorded an operating loss of almost SEK 50 billion. In the fall of 1992, the government guaranteed all banks’ liabilities, took over two of the largest banks, and announced it would create the Bank Support Authority to manage …
