We examine optimal taxation and social insurance with adverse selection in competitive insurance markets. In the previous literature, it has been shown that, with perfect insurance markets, social insurance improves welfare since it is able to redistribute without creating distortions. This result has been taken as robust to the introduction of adverse selection as this would only provide addit...

purpose: this study wants to find any relationship between the numbers of purchase and the income the customer brings to the company. the attempt is to find those customers who buy more than one life insurance policy and represent the signs of good payments at the same time by the help of data mining tools. design/ methodology/ approach: the approach of this research is to use data mining tools...

abstract main objective of this paper is the investigation the effect of support policies of government on income risk of poultry producers in iran for the 1989-2006. ccv index was used to investigate amount of variation that cause each support policies (market price support, support of agricultural inputs, outputs insurance) on income risk variation of producers. the results of this study show...

We establish the validity of subsampling confidence intervals for the mean of a dependent series with heavy-tailed marginal distributions. Using point process theory, we study both linear and nonlinear GARCH-like time series models. We propose a data-dependent method for the optimal block size selection and investigate its performance by means of a simulation study. JEL CLASSIFICATION NOS: C10,...

This paper analyzes the identifying power of weak convexity assumptions in treatment effect models with endogenous selection. The counterfactual distributions are constrained either in terms of the response function, or conditional on the realized treatment, and sharp bounds on the potential outcome distributions are derived. The methods are applied to bound the effect of education on smoking. ...

The debate in equilibrium selection appears to have culminated in the formation of two schools of thought: those who favor equilibrium selection based on rational coordination and those who favor zero-rationality adaptation. We examine four deductive selection principles and find that each fails to explain experimental data. We propose an inductive selection principle based on simple learning d...
