Optimal investment policy and dividend payment strategy in an insurance company

We consider in this paper the optimal dividend problem for an insurance company whose uncontrolled reserve process evolves as a classical Cram\'{e}r--Lundberg process. The firm has the option of investing part of the surplus in a Black--Scholes financial market. The objective is to find a strategy consisting of both investment and dividend payment policies which maximizes the cumulative expected discounted dividend pay-outs until the time of bankruptcy. We show that the optimal value function is the smallest viscosity solution of the associated second-order integro-differential Hamilton--Jacobi--Bellman equation. We study the regularity of the optimal value function. We show that the optimal dividend payment strategy has a band structure. We find a method to construct a candidate solution and obtain a verification result to check optimality. Finally, we give an example where the optimal dividend strategy is not barrier and the optimal value function is not twice continuously differentiable.Comment: Published in at http://dx.doi.org/10.1214/09-AAP643 the Annals of Applied Probability (http://www.imstat.org/aap/) by the Institute of Mathematical Statistics (http://www.imstat.org

Culture, beliefs and economic performance

Beliefs are one component of culture. Data from the World Values Survey is available on a subset of beliefs concerning (broadly) meritocracy and poverty that appear relevant for economics. We document how they vary as well as their distribution across countries. We then correlate these measures of beliefs with economic growth and compare them with institutional and geographical determinants of income. A strong negative relationship is found between leftist economic beliefs and growth but little evidence is found of a relationship with respect to non-economic beliefs. Finally, we briefly discuss some causal effects on beliefs. The evidence suggests that higher country risk and more dependence on natural resources shifts nations to a more leftist set of economic beliefs. Overall the evidence supports the view that cultural specificities may explain why certain institutions cannot be transplanted between nations with different cultural histories and underlines the limit to policy activism

A note on Fairness and Redistribution

We note some problems in Alesina and Angeletos (2005) and suggest a way to maintain the key insight of that paper, which is that a demand for fairness could lead to different economic systems such as those observed in France versus the US (multiple equilibria).Inequality, taxation, redistribution, political economy.

Are Politicians Really Paid Like Bureaucrats?

We provide the first empirical analysis of gubernatorial pay. Using US data for 1950-90 we document, contrary to widespread assumptions, substantial variation in the wages of politicians, both across states and over time. Gubernatorial wages respond to changes in state income per capita and taxes, after controlling for state and time fixed effects. The economic effects seem large: governors receive a 1 percent pay cut for each ten percent increase in per capita tax payments and a 4.5 percent increase in pay for each ten percent increase in income per capita in their states. There is strong evidence that the tax elasticity reflects a form of reward-for-performanc.' The evidence on the income elasticity of pay is less conclusive, but is suggestive of rent extraction' motives. Lastly, we find that democratic institutions seem to play an important role in shaping pay. For example, voter-initiatives and the presence of significant political opposition lead to large reductions in the income elasticity of pay, and to large increases (at least double) in the tax elasticities of pay, relative to the elasticities that are observed when these democratic institutions are weaker.
