Creatine is a nitrogenous organic acid which supplies energy to body cells and enhances physical performance. Using the Young Finns Study combined with the Finnish Linked employer-employee data we show that quantities of creatine measured in 1980 prior to labour market entry affect entrepreneurial success as measured by capital income accumulation over the period 1993–2010 (in particular for females). However, we do not find evidence that creatine affects the propensity to become an entrepreneur. Our study contributes to the emerging literature on biomarkers and entrepreneurship.  相似文献

Two decades of research have established pronounced exporter productivity premia (EPP) and exporter size premia (ESP). Yet, we do not know why such exporter premia differ so widely in magnitude across countries or sectors? We take this question to the theory and to the data. We derive the sectoral EPP and ESP in a standard heterogeneous firms trade model and apply the insights from the model to guide our empirical investigation of detailed Danish firm-level data. We show that a significant share of the observed variation in EPP and ESP across sectors can be accounted for by sector differences in the underlying variation in productivity dispersion, variable trade costs, the ratio of fixed export costs to fixed costs of production, and the elasticity of demand.  相似文献

In Western Europe in the last two decades the unemployment rate has increased during cyclical downturns only to persist at or around the higher level in the following phase of economic recovery. One of the most notable exceptions to this pattern of unemployment persistence, often termed hysteresis, is the United States. The following article examines the empirical evidence and the possible theoretical explanations for this difference.  相似文献

This paper presents data from a survey of large and medium-sized industrial enterprises in Ukraine after privatization. To analyze this data, regression equations are estimated and explain the response of restructuring and performance indicators to ownership structures, competitive pressures, and hardening budget constraints. While ownership matters less for restructuring activity than competition and budget constraints, concentrated outside ownership does have a significant positive impact on the firm's performance. This research was financially supported by a grant from the International Association for Promotion of Cooperation with Scientists in the New Independent States of the Former Soviet Union (952-0280) and by a Research Fellowship provided by Konferenz der Deutschen Akademien der Wissenschaften, sponsored by Volkswagen Stiftung.  相似文献

Modeling Methods for Discrete Choice Analysis   总被引:2,自引:3,他引:2  
This paper introduces new forms, sampling and estimation approaches fordiscrete choice models. The new models include behavioral specifications oflatent class choice models, multinomial probit, hybrid logit, andnon-parametric methods. Recent contributions also include new specializedchoice based sample designs that permit greater efficiency in datacollection. Finally, the paper describes recent developments in the use ofsimulation methods for model estimation. These developments are designed toallow the applications of discrete choice models to a wider variety ofdiscrete choice problems.  相似文献

The German currency is held and used abroad because of its liquidity and stability relative to most of the world’s currencies. DM banknotes are used as a transactions medium and as a store of value. The number of these which are held abroad is of interest to policy-makers for various reasons, but is rather difficult to estimate. Professor Seitz outlines the results of several estimation methods and discusses the monetary policy consequences.  相似文献

This paper examines theoretically and empirically how employment protection legislation affects location decisions of multinationals. We depart from the “conventional wisdom” by examining not only the effect of protection on inward foreign direct investment (FDI), but also a country’s ability to “anchor” potential outward investment. Based on our simple theoretical framework, we estimate an empirical model, using data on bilateral FDI and employment protection indices for OECD countries, and controlling for other labour market institutions and investment costs. We find that, while an “unfavourable” employment protection differential between a domestic and a foreign location is inimical to FDI, a high domestic level of employment protection tends to discourage outward FDI. The results are in line with our conjecture that strict employment protection in the firm’s home country makes firms reluctant to relocate abroad and keeps them “anchored” at home.  相似文献
