Die Analyse (mit einem "Constant Market Shares" Modell) über die Wettbewerbsfähigkeit und Struktur hat ergeben, dass sich in der österreichischen Außenwirtschaft mit Gütern in den vergangenen Jahren die Wettbewerbsfähigkeit verschlechtert hat. Es zeichnen sich auch strukturelle Probleme...

We study the macroeconomic and welfare effects of decumulating government debt in an overlapping generations model with skill heterogeneity and productive and non-productive government programs. Our results are: First, in the small open economy model calibrated to Greece, the spending-based...

We investigate whether late redistribution programs that can be targeted toward low income families, but that may distort savings decisions, can “dominate” early redistribution programs that cannot be targeted as a result of information constraints. We use simple two-period overlapping...

We formulate an overlapping generations model with skill heterogeneity and productive and non-productive government programs to study the macroeconomic and intergenerational welfare effects caused by risk premium shocks and government debt reductions. We demonstrate that in a small open economy...

We explore the determinants of inspection outcomes across 1.6 million Occupational Safety and Health Agency (OSHA) audits from 1990 through 2010. We find that discretion in enforcement differs in state and federally conducted inspections. State agencies are more sensitive to local economic...

We quantify the effects of the Affordable Care Act (ACA) using a stochastic general equilibrium overlapping generations model with endogenous health capital accumulation calibrated to match U.S. data on health spending and insurance take-up rates. We find that the introduction of an insurance...

We investigate the association between age and medical spending in the U.S. using data from the Medical Expenditure Panel Survey. We estimate a partially linear seminonparametric model and construct “pure” life-cycle profiles of health spending simultaneously controlling for time effects...

We develop a hybrid algorithm using Genetic Algorithms (GA) and Simulated Annealing (SA) to solve multi-objective step function maximization problems. We then apply the algorithm to a specific economic problem which is taken out of the corporate governance literature.

In many emerging economies pension programs of public sector workers are more generous than pension programs of private sector workers. In this paper we investigate public pension reforms that improve efficiency and welfare by reallocating government resources from non-productive public pensions...

We investigate the effects of extending the coverage of social security to uncovered elderly individuals in the informal sector in developing countries. We use a stochastic overlapping generations framework and incorporate important characteristics of developing countries including family...
