We propose a general framework for analyzing structural limited dependent variable models where an endogenous regressor is also limited in range. A copula-based modeling of structural joint distributions permits us to implement a full information maximum likelihood estimation of parameters. We apply this modeling strategy to the March 1992 and 2002 CPS data for estimating the average partial ef...
Age Structure of the Workforce and Firm Performance In this contribution, we examine the interrelation between corporate age structures and firm performance. In particular, we address the issues, whether firms with young rather than older employees are successful and whether firms with homogeneous or heterogeneous workforces are doing well. Several theoretical approaches are discussed with resp...
This paper examines how Congress’s 2008 expansion of who is disabled under the Americans with Disabilities Act (ADA) impacts the labor market outcomes of newly covered individuals. Focusing on obese individuals, I exploit variation in coverage of obesity before and after the 2008 expansion to identify effects of the legal change, but I find no improvement in the labor market outcomes of the obe...
This empirical research note documents the relationship between composition of a firm's workforce (with a special focus on age and gender) and its performance with respect to innovative activities (outlays and employment in research and development (R&D)) for a large representative sample of enterprises from manufacturing industries in Germany using unique newly available data. We find that fir...
This paper investigates the differences in the matching process of job seekers and vacancies to be filled between different educational and occupational groups. To investigate this issue, matching functions are estimated across different occupations and educational cohorts, that is, on an even lower level of aggregation than previously investigated in the literature, and along different dimensi...
This paper evaluates the extent of interindustry, and inter-regional wage spillovers across the UK. A large literature exists suggesting that wages elsewhere affect wage determination and levels of satisfaction, but this paper extends the analysis to examine the effects of inward investment in the process. Thus far the specific effect of foreign wages on domestic wage determination has not been...
We examine aspects of primordial star formation in the presence of a molecular hydrogen-dissociating ultraviolet background. We compare a set of AMR hydrodynamic cosmological simulations using a single cosmological realization but with a range of ultraviolet background strengths in the Lyman-Werner band. This allows us to study the effects of Lyman-Werner radiation on suppressing H2 cooling at ...
Çağımızda bir taraftan teknolojideki gelişmeler ve dijitalleşme, diğer yaşanan demografik değişim/dönüşüm bireylerin emek piyasasında muhatap oldukları işleri meslekleri de etkilemektedir. Emek piyasasındaki bu dönüşüm sonucunda ortaya çıkan taleplerin ne ölçüde karşılanıp karşılanmadığı, piyasasına girmeleri veya girememeleri sonucunu doğurmaktadır. Bu noktada önemli rol üstlenmesi beklenen ka...
One of the most important methods employed to measure the market risk is value at risk calculation method. In this study, the value at risk of banks listed on the Tehran Stock Exchange and Over-the-counter (OTC) are calculated using parametric model, Monte Carlo simulation, historical simulation and Two-Sided Power (TSP) Distribution. The sample includes all listed banks in Iran. The results sh...
هدف مقاله بررسی ارتباط اثرات نرخ مشارکت اقتصادی بر نرخ بیکاری در استان های ایران و آزمون «فرضیه تغییرناپذیری بیکاری» است. برای این منظور از داده های فصل اول 1384 تا فصل سوم 1394 و روش های مختلف تک معادله ای، سیستم معادله و داده های تابلویی استفاده شده است. نتایج نشان می دهد در اغلب استان ها و همچنین در متوسط کشور، فرضیه تغییرناپذیری نرخ بیکاری به واسطه شوک های کوتاه مدت در نرخ مشارکت اقتصادی بر...
