Analyses of central bank independence (CBI) have generated two sets of apparently contradictory results - CBI appears to be both inversely related to inflation and positively related to the rise in unemployment and slowdown in economic growth during disinflations. I suggest that these results may issue from autonomous central banks being associated with sharper, more aggressive disinflations. To test the proposition I use two measures of policy stance, one of which contains more information concerning policymaker's expectations than has heretofore been the case. The results suggest a need to qualify yet further the optimality of CBI.

While there is a strong theoretical foundation for the relationship between business sectors' political spending and the policy benefits that they receive, the empirical support for it is mixed. We use the logic of this exchange to examine a policy area that directly and significantly affects all businesses, and is thus a most likely case, taxation. Using principally firm-level tax rates of a large random sample of U.S. corporations for the 1998–2005 time period, we determine whether lobbying has measurable effects on firm-level tax rates. Contrary perhaps to popular belief, or at least anecdotal illustration, we find after controlling for firm size and industry-level tax rates, among other controls, that there is no discernible effect of political spending on firm-level taxation: firms that spend more in an effort to affect policy generally or tax policy specifically are no more likely to benefit from lower tax rates. We also examine the possibility that firms in the same industry coordinate efforts to affect tax rates. While we find limited evidence that firms occasionally coordinate within industries – or at least lobby simultaneously – to affect tax rates, perhaps more importantly, we determine that free-riding by smaller firms at the expense of the largest firms is rampant.

Do neoliberal economic policies help or hinder human development? Many have argued that such policies promote economic stability and growth, which may have indirect positive effects on human welfare. Others claim that neoliberal policies retard human development. We argue that neoliberal economic policies may improve the human welfare in ways that are independent of their effects on economic performance. Specifically, this paper hypothesizes that open international trade policies, low-inflation macroeconomic environments, and market-oriented property rights regimes promote human development across the world. We test this argument by examining the impact of several measures of neoliberal policies on infant mortality rates across the world between 1960 and 1999. Results suggest that openness to imports, long-term membership in the GATT and WTO, low rates of inflation, and effective contract enforcement are each associated with lower rates of infant mortality across the world, even when controlling for countries' economic performance.

To ascertain whether youth bulges are related to violent conflict and whether violent conflict falls off when youth bulges are followed by busts, we analyzed data from 1998–2005 covering 127 nations. Controlling for variables representing such factors as socio-development, macroeconomics, technology advancement, government capacity, and geo-politics, we find that youth bulges are related to violent conflict, but when youth bulges are followed by busts violent conflict grows rather than diminishes contrary to the prediction we make. From this analysis, we draw implications for further research and analysis with regard to doing business in violence-prone nations.
