We examine the relationship between cyclical fluctuations and macroeconomic, institutional, and cultural indicators for 46 countries from Europe and the Mediterranean basin. In the Mediterranean cycles are different: the duration of expansions is shorter; the amplitude of recessions is larger; and cyclical synchronization is smaller than elsewhere. Differences in cultural indicators have strong and significant associations with differences in the persistence and volatility of cyclical fluctuations and their synchronization.  相似文献

We consider a multi-supplier, single-manufacturer supply chain where each supplier sells a different component at varying quality levels. The manufacturer has to decide on which quality level to choose for each component, trading-off the total cost and total quality. Each supplier decides on a price per unit quality level for its component. We characterize the strategic interaction among the suppliers and analyze the inefficiencies. We find that the inefficiencies due to such quality competition can be quite significant. We then propose and analyze several mechanisms, such as quality-price schedules and revenue sharing, that restore efficiency.  相似文献

This article examines the role of the extensive and intensive margins of labor input in the context of a business cycle model with a financial friction. We document significant variation in the hours worked per worker for many emerging-market economies using manufacturing data. Both employment and hours worked per worker are positively correlated with each other and with output. We show that a search-theoretic context in a small open-economy model requires a small wealth effect to explain these regularities at the expense of a smaller wage response. On the other hand, introducing a financial friction in the form of a working capital requirement can explain the observed movements of labor market variables such as employment and hours worked per worker, as well as other distinguishable business cycle characteristics of emerging economies. These include highly volatile and cyclical real wages, labor share, and consumption.  相似文献

Abstract

In this paper, we report the findings from the data we collected from a survey in order to measure how common research ethics education in economics is. We have found out that (1) research ethics is taught in only a very few economics departments around the globe; (2) topics related to research ethics are not taught in courses on economics and ethics; and (3) the number of papers published in specialised peer-reviewed journals on economics education is only a tiny fraction of the number of papers published in these journals. There has been no evidence in economics showing that economics departments have taken strong initiative on teaching research ethics to undergraduate and graduate students.  相似文献

Fundamental components of the economy in developing countries are efficiency and productivity. These concepts prevail all around the world and many studies have been conducted on the issue. With the rapidly increasing population, productivity and efficiency of the agricultural sector have become even more important in order to meet the food needs of the population. In this study, NUTS (The Nomenclature of Territorial Units for Statistics) regions in Turkey were accepted as an decision making unit and the efficiency values of these regions, changes in the total factor productivity and technology were calculated for the 10-year period covering 1994–2003. Methods of Data Envelopment Analysis and Malmquist Productivity Index were used in order to measure the crop production of NUTS1 regions in Turkey. There has been a decrease in the technical efficiency and total factor productivity in the regions, excluding the Western Marmara, the Aegean, the Mediterranean and The Eastern Blacksea Region, within the 10 year period analyzed. The decrease reflected all over the country. The decrease was caused by the fact that the real price level remained the same; the real prices of the inputs increased despite the decreasing population economically active in the agricultural sector, and the difficulty experienced in integration of the latest technology to the agricultural sector. Regional differences in terms of productivity and efficiency is another striking finding.  相似文献

We consider a single stage inventory system with stochastic capacity. The manager receives forecasts from the upstream source about future capacity availability within an information horizon, referred to as “advance supply information”. We study two main questions: (i) How can advance supply information be utilized when making replenishment decisions? (ii) What is the value of such information sharing, compared to a fixed base-stock policy? We show that state-dependent base-stock policies are optimal. We develop easily computable and implementable heuristic policies. We numerically test the accuracy of the approximations and analyze the value of collaboration under various business scenarios.  相似文献

Errors in the history of economic analysis often remain uncorrected for long periods due to positive epistemic costs (PEC) involved in allocating time to going back over what older generations wrote. In order to demonstrate this in a case study, economists' practice of the “Coase Theorem” is reconsidered from a PEC point of view.  相似文献

This paper presents estimates of the degree of returns to scale using nonparametric measures of primal and dual productivity for 2-digit US manufacturing industries. As part of the analysis, the cyclical behaviour of primal and dual productivity measures are considered, time-varying markups are allowed for, and the small sample properties of the instrumental variables estimator used to derive the estimates from the primal and dual relations examined. Both the primal and dual estimates indicate the existence of increasing returns to scale for the durable goods industries. The simulation results indicate there is a slight tendency for the dual equation estimates to overestimate the degree of returns to scale. However, small sample bias appears to be most severe for the non-durable goods industries.  相似文献

The Effect of Work Experience on Female Wages and Labour Supply   总被引:1,自引:0,他引:1  
This paper develops and implements a semiparametric estimator for investigating, with panel data, the importance of human capital and time nonseparable preferences to females when aggregate shocks are present. It provides a set of conditions for making statistical inferences about agents' expectations of their correlated future choices, from a short panel. Under the assumption that observed allocations are Pareto optimal, a dynamic model of female labour supply and participation is estimated, in which experience on the job raises future wages, and time spent off the job in the past directly affects current utility (or, indirectly through productivity in the no-market sector).  相似文献

The objective of this article is two-fold. First, we developa theoretical model to investigate the impact of political riskon irreversible investment. Second, we apply our model to ananalysis of the effects of risk of separation of the provinceof Quebec from the Canadian federation. We model the probabilityof a regime switch using the properties of the electoral processand examine the response of investment to changes in the riskof separation. We consider the impact of investors' perceptionof the risk of separation and financial market volatility separately.We show that political risk has a depressing impact on investmenteven if the "bad" regime has never been observed in the sample.(JEL Codes: E22, D92, O16, O11)  相似文献
