Bigger governments raise the possibilities for corruption; more corruption may in turn raise the support for redistributive policies that intend to correct the inequality and injustice generated by corruption. We formalize these insights in a simple dynamic model. A positive feedback from past to current levels of taxation and corruption arises either when wealth originating in corruption and r...

This paper uses panel data from African countries and a dynamic panel estimator to investigate the effects of corruption on economic growth and income distribution. I find that corruption decreases economic growthdirectly and indirectly through decreased investment in physical capital. A unit increase in corruption reduces the growth rates of GDP and per capita income by between 0.75 and 0.9 pe...

Many social commentators have raised concerns over the possibility that increased sorting in society can lead to greater inequality. To investigate this, we construct a dynamic model of intergenerational education acquisition, fertility and marital sorting and parameterize the steady state to match several basic empirical ...ndings. We ...nd that increased marital sorting will signi...cantly in...

This paper examines the recent trends in regional income disparity and urban-rural income inequality in the Chinese economy. It finds that the income disparity between the eastern and western region had declined, but the urban-rural income inequality continued to rise in all four regions during the period under consideration. Moreover, the urban-rural income disparity increased more rapidly in ...

We present a new approach to estimate the relaxation speed to equilibrium of interacting particle systems. It is based on concentration inequalities and coupling. We illustrate our approach in a variety of examples for which we obtain several new results with short and non technical proofs. These examples include the symmetric and asymmetric exclusion process and high-temperature spin-flip dyna...

We study a class of dynamic thermal sub-differential contact problems with friction, for long memory visco-elastic materials, without the clamped condition, which can be put into a general model of system defined by a second order evolution inequality, coupled with a first order evolution equation. We present and establish an existence and uniqueness result, by using general results on first or...

This paper describes formulation and management of constraints that, combined with a nonlinear optimization algorithm, enable interactive geometrically aware manipulation of articulated objects. Going beyond purely kinematic or dynamic approaches, our solution method directly employs geometric constraints to ensure noninterpenetration during object manipulation. We present the formulation of th...

This paper examines the impact of inequality in access to credit on efficiency in extraction from a common resource. A dynamic model is developed, where agents strategically choose the level of sunk capacity and the consequent extraction path. Sunk capacity is a function of cost of credit and serves as a commitment device to deter entry or force exit. Contrary to previous studies based on stati...

Demographic transition due to population aging is an emerging issue throughout the developing world, and especially in China, which has undergone demographic transition more rapidly than most industrial economies. This paper quantifies the distributional effects in the context of demographic transition using the integrated recursive dynamic computable general equilibrium (CGE) model with top-do...
