This article studies the process from data acquisition to policy decision in relation to an optimum policy on global warming. Policymakers must be reasonably skeptical before proposing remedies to curb warming, but policymakers cannot await the final proof of any proposal's merit. Balancing...

Are financial intermediaries inherently unstable? If so, why? What does this suggest about government intervention? To address these issues we analyze whether model economies with financial intermediation are particularly prone to multiple, cyclic, or stochastic equilibria. Four formalizations...

In the 1960s, Norway lagged behind its Scandinavian neighbors in the aggregate value of economic production per capita, as it had for decades. By the 1990s, Norway had caught up with and forged ahead of Denmark and Sweden. When and why did Norway catch up? The discovery and extraction of oil in...

Different types of taxation include the market value of housing or housing returns in their tax base, making it essential to obtain accurate and up-to-date assessments of property values. However, to value residential property represents a major challenge for tax administrations due to...

How taxation influences income mobility is largely a neglected topic. In this study we discuss the relationship between taxation and income mobility by analyzing both macro and micro data. Administrative register data based on income tax returns are used to produce individual and aggregate...

In many developing countries, there does not exist a time series of nationally repre- sentative household budget or income surveys, while there often are urban household surveys as well as nationally representative Demographic and Health Surveys (DHS) which lack information on incomes. This...

In this paper, we revisit the association between happiness and inequality. We argue that the perceived fairness of the income generation process affects this association. Building on a two-period model of individual life-time utility maximization, we predict that persons with higher perceived...

Martin Ravallion ("Why Don't We See Poverty Convergence?" American Economic Review, 102(1): 504-23; 2012) presents evidence against the existence of poverty convergence in aggregate data despite the conditional convergence of per capita income levels and the close linkage between growth and...

Using newly comprehensive data and tools from the Global Consumption and Income Project or CGIP, covering most of the world and five decades, we present a portrait of the changing global distribution of consumption and income and discuss its implications for our understanding of inequality,...

Interest in the emergence of a global middle class has resulted in a number of attempts to identify and enumerate who belongs to it . Current research provides wildly different estimates about the size and evolution of the global middle class because of a lack of consensus on appropriate...
