基於Bma方法的長期經濟增長因素確定—— 一個研究綜述, 路征, 鄧翔 Nov 2008

基於Bma方法的長期經濟增長因素確定—— 一個研究綜述, 路征, 鄧翔

Zheng Lu (Chinese: 路征)

將貝葉斯統計理論引入經濟學研究具有重要的理論與實踐價值,並已被國外經濟研究者廣泛應用於經濟研究中。BACE 方法是基於 BMA(Bayesian Model Averaging)的一個改進,由Doppelhofer 等提出並利用其研究長期經濟增長因素的確定,認為許多的潛在因素與經濟增長相關,從而支持了 Sala-i-Martin 而不是 Ross Levine 和 David Renelt 的研究結論。


Entry Costs And Economies Of Scope In Multiproduct Firms' Decisions, Xosé-Luís Varela-Irimia Nov 2008

Entry Costs And Economies Of Scope In Multiproduct Firms' Decisions, Xosé-Luís Varela-Irimia

Xosé-Luís Varela-Irimia

This paper computes the scope economies associated to the commercialization of several product varieties by multiproduct firms, in a dynamic oligopoly setting. Goods are differentiated and firms decide on firm entry and exit, product entry and exit, quality and pricing. The model is applied to the Spanish automobile market. Results show moderate entry costs and substantial cost reductions when introducing a second product as compared to the first, indicating that multiproduct firms benefit from strong economies of scope when expanding their range of products. However, those economies disappear after five products have been introduced, suggesting a U-shaped curve for entry …


Water Borne Diseases And Rural Development In Sudan Study Of Malaria In Gezira Irrigated Agricultural Scheme, Professor Issam A.W. Mohamed Oct 2008

Water Borne Diseases And Rural Development In Sudan Study Of Malaria In Gezira Irrigated Agricultural Scheme, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

Gezira irrigated scheme is globally one of the biggest agricultural productive units administratively managed. It has seen deteriorating productivity for the past two decades. There cries that it should be privatized. That was seriously taken by the government in an economic liquidation of its assets. However, in this study we discuss analyze other aspects than the previously mentioned aspects of production parameters. We focus of health economics and how gradual negligence led to the prevalence of waterborne diseases. That degenerated farmers' abilities to produce. The present study was carried out in the Gezira scheme to measure the impact of water …


Asymmetric Dynamic Pricing In A Local Gasoline Retail Market, Felipe Balmaceda Assoc Prof., Paula Soruco Sep 2008

Asymmetric Dynamic Pricing In A Local Gasoline Retail Market, Felipe Balmaceda Assoc Prof., Paula Soruco

Felipe Balmaceda

Asymmetric-price adjustment is a common phenomenon in many markets around the world, particularly in retail gasoline markets. This paper studies the existence of this phenomenon in the retail gasoline market in the city of Santiago, Chile, using a data set of weekly gas station prices that covers a period of almost four years. We found that prices adjust asymmetrically, and the asymmetry is different for branded gas stations and unbranded stations. In addition, we found that the asymmetry for high-margin stations is statistically equivalent to that for low-margin stations. This evidence is suggestive of collusion as a rationale for the …

Designing A Successful Pbrn In Public Health: Key Concepts, Glen P. Mays, Sharla A. Smith May 2008

Designing A Successful Pbrn In Public Health: Key Concepts, Glen P. Mays, Sharla A. Smith

Glen Mays

Successful public health practice-based research networks (PBRNs) will require organizational, financial, and intellectual resources that allow practitioners and researchers to mount relevant studies in real-world public health settings. This brief outlines characteristics likely to be important to the success of public health PBRNs, based on the experience of PBRNs in other practice settings


Econometric Studies Of Higher Education, Ronald G. Ehrenberg Apr 2008

Econometric Studies Of Higher Education, Ronald G. Ehrenberg

Ronald G. Ehrenberg

[Excerpt] The economics of higher education goes back at least to Adam Smith, who suggested over 200 years ago in the Wealth of Nations that professors should get paid based upon the number of students enrolled in their classes. The econometrics of higher education is of much more recent vintage and emerged from the development of human capital theory and the efforts to estimate rates of return to education in the 1960s and 1970s. In the sections that follow, I survey the various strands of the literature on the econometrics of higher education that have developed during the last 40 …

Finding Order In Complexity: A Typology Of Local Public Health Delivery Systems, Glen Mays Mar 2008

Finding Order In Complexity: A Typology Of Local Public Health Delivery Systems, Glen Mays

Glen Mays

Public health decision-makers and researchers currently lack an evidence-based framework for describing, classifying, and comparing public health delivery systems based on their organizational components, operational characteristics, and division of responsibility. Related typologies developed in the health services sector have proven extremely valuable for policy and administrative decision-making as well as for ongoing research. Performance assessment, quality improvement, and accreditation activities are now blossoming in public health—adding urgency to the need for classification and comparison frameworks. This brief describes a newly-developed empirical typology for local public health systems and highlights its policy and managerial applications.


The Relationship Between Poverty And Economic Growth Revisited, Lonnie K. Stevans, David N. Sessions Mar 2008

The Relationship Between Poverty And Economic Growth Revisited, Lonnie K. Stevans, David N. Sessions

Lonnie K. Stevans

It has been shown in prior research that increased economic growth reduces poverty. Authors have also found that the effect of growth in GDP on poverty growth has either diminished or remained unchanged over time and the 1980s economic expansion in the U.S. had no affect on poverty. Using a formal error-correction model, we find that increases in economic growth are significantly related to reductions in the poverty rate for all families. Specifically, GDP growth was found to have a more pronounced effect on poverty during the expansionary periods of the 1960s, 1970s, 1980s, 1990s, and 2000s. Other findings include …


On Consumers’ Valuation Of Nutritional Labels On Food Away From Home Products, Andreas Drichoutis, Panagiotis Lazaridis, Rodolfo M. Nayga, Jr. Jan 2008

On Consumers’ Valuation Of Nutritional Labels On Food Away From Home Products, Andreas Drichoutis, Panagiotis Lazaridis, Rodolfo M. Nayga, Jr.

Andreas Drichoutis

We examine consumers’ valuation for Food Away From Home (FAFH) products with and without nutritional labels using experimental auctions. We presented subjects with three different nutritional information schemes: a EU type label, a US type label and a Traffic Light (TL) label. Our results indicate that subjects bid more for the products with nutritional labels. However, among products with nutritional information, subjects’ willingness to pay values differ depending on the type of nutritional label.

Investment Credit Availability - Bank Enterprise Relations In Poland, Joanna Tyrowicz Jan 2008

Investment Credit Availability - Bank Enterprise Relations In Poland, Joanna Tyrowicz

Joanna Tyrowicz

The complaints about insufficient private investment are frequent in Poland. Equally often do we hear the criticism of the monetary policy pointing to excessively high interest rates. This paper estimates the speed of upward adjustment of loan rates relative to downward adjustment, accounting for dierent market segments and products. The empirical results show that for the investment credit upward adjustment is fast, but downward adjustment essentially does not occur. Consumer credit products demonstrate positive values for the speed of both adjustments although still upward changes occur faster than downwards ones. These ndings suggest that banks may tend to discriminate entrepreneurs …

Gone In 60 Seconds: The Absorption Of News In A High-Frequency Betting Market, Babatunde Buraimo, David Peel, Rob Simmons Jan 2008

Gone In 60 Seconds: The Absorption Of News In A High-Frequency Betting Market, Babatunde Buraimo, David Peel, Rob Simmons

Dr Babatunde Buraimo

This paper tests for efficiency in a betting market that offers high-frequency data, the Betfair betting exchange for wagering on outcomes of English Premier League soccer matches. We find clear evidence of rapid adjustment of prices to large disturbances (news). Full adjustment takes place within a one minute interval after the news. This suggests that this particular wagering market is not just efficient at pre-match prices but is also efficient in the face of events within games.


Do R&D Programs Of Different Government Levels Overlap In The European Union?, Andrea Fernandez-Ribas, Isabel Busom Jan 2008

Do R&D Programs Of Different Government Levels Overlap In The European Union?, Andrea Fernandez-Ribas, Isabel Busom

Andrea Fernandez-Ribas

Multiple levels of government currently design and implement research and innovation programs both in the US and in Europe. Empirical analysis of interdependencies among programs has not been fully explored, however. Our contribution is a first step in understanding potential complementarities across R&D programs. Using a sample of Spanish manufacturing firms, we study the determinants of firms’ participation in national and in European level research programs and test for differences across programs. Our results suggest that firms’ participation in European and national R&D programs is largely driven by different factors. We interpret these results as suggesting that, ex-post, there is …

Modes, Weighted Modes, And Calibrated Modes: Evidence Of Clustering Using Modality Tests, Daniel Henderson, Christopher Parmeter, R. Russell Dec 2007

Modes, Weighted Modes, And Calibrated Modes: Evidence Of Clustering Using Modality Tests, Daniel Henderson, Christopher Parmeter, R. Russell

Christopher F. Parmeter

We apply recent results from the statistics literature to test for multimodality of worldwide distributions of several (unweighted and population-weighted) measures of labor productivity. Specifically, we employ Silverman (Bump) and Dip modality tests, calibrated to correct for their incorrect asymptotic levels. We show that test results are sensitive to the test statistic employed and to population weighting. But regardless of the statistical criterion used, multimodality is present throughout, or emerges during, our sample period (1960–2000). We also examine (a) movements of economies between modal clusters and (b) relationships between certain key development factors and multimodality of the productivity distribution.

Fertility And The Health Of Children: An Application Of A Nonparametric Conditional Late Estimator, Daniel Henderson, Daniel Millimet, Christopher Parmeter, Le Wang Dec 2007

Fertility And The Health Of Children: An Application Of A Nonparametric Conditional Late Estimator, Daniel Henderson, Daniel Millimet, Christopher Parmeter, Le Wang

Christopher F. Parmeter

Although the theoretical trade-off between the quantity and quality of children is well established, empirical evidence supporting such a causal relationship is limited. This chapter applies a recently developed nonparametric estimator of the conditional local average treatment effect to assess the sensitivity of the quantity-quality trade-off to functional form and parametric assumptions. Using data from the Indonesia Family Life Survey and controlling for potential endogeneity of fertility, we find mixed evidence supporting the trade-off.


Heterogeneity In Smoker Preferences For Increased Efficacy Of Cessation Therapies, Robert Paterson, Kevin Boyle, Christopher Parmeter, James Neumann, Paul De Civita Dec 2007

Heterogeneity In Smoker Preferences For Increased Efficacy Of Cessation Therapies, Robert Paterson, Kevin Boyle, Christopher Parmeter, James Neumann, Paul De Civita

Christopher F. Parmeter

Promoting cessation is a cornerstone of tobacco control efforts by public-health agencies. Economic information to support cessation programs has generally emphasized cost-effectiveness or the impact of cigarette pricing and smoking restrictions on quit rates. In contrast, this study provides empirical estimates of smoker preferences for increased efficacy and other attributes of smoking cessation therapies (SCTs). Choice data were collected through a national survey of Canadian smokers. We find systematic preference heterogeneity for therapy types and SCT attributes between light and heavy smokers, as well as random heterogeneity using random parameters logit models. Preference heterogeneity is greatest between length of use …

The Effect Of Measurement Error On The Shape Of The World Distribution Of Income, Christopher Parmeter Dec 2007

The Effect Of Measurement Error On The Shape Of The World Distribution Of Income, Christopher Parmeter

Christopher F. Parmeter

This note examines the robustness that two modes exist in the world's density of per capita income. Our results suggest that this bimodal feature is robust and are arrived at using recently developed nonparametric deconvolution techniques.
