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
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
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
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
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
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
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
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
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.
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
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
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
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 …

Democracy Autocracy And Macroeconomic Performance In Pakistan, Nasir Iqbal, Sardar Javaid Iqbal Khan, Muhammad Irfan Chani
Democracy Autocracy And Macroeconomic Performance In Pakistan, Nasir Iqbal, Sardar Javaid Iqbal Khan, Muhammad Irfan Chani
Muhammad Irfan Chani
Pakistan showed a healthy growth rate of 5.6 percent during the entire history and faced many ups and downs in economic growth due to dramatic changes in political regimes. The literature shows mixed results regarding the impact of autocracy or democracy on economic growth. The aggregate growth of the economy under autocracy remained better as compared to democratic period. Financial indicators show consistent path through out the history of Pakistan. Different trade policies are designed in different regime to run the external sector and the impact of each policy was different.
