Corruption in dictatorships

In this paper, we consider a simple model capable of explaining why some dictatorships choose to extract rents via seemingly inefficient institutions. In particular, this paper focuses on institutions associated with high levels of corruption and examines the conditions under which such institutions could serve the interests of a dictatorship. Developing such a model requires that we pose alternative institutions that dictators can choose to extract rents. Using this framework, this paper builds a model providing a theoretical basis for some stylized facts about the observed crosscountry variation in corruption levels. Specifically, the model motivates a rationale for the finding that higher levels of corruption are observed in countries characterized as having more heterogeneous populations, longer expected dictator tenure, and more severe punishment norms. The model is then estimated using international country level data.     

The effects of open skies agreements on transatlantic air service levels

This paper examines the effects of Open Skies agreements on service levels in transatlantic aviation markets. Our route analysis reveals that Open Skies agreements between European countries and the US have resulted in both increases and decreases in service levels. Of the 22 European countries with US Open Skies agreements in place by 2007, only seven demonstrated increases in service levels while six showed reductions. Five countries saw no significant change and the remaining four have yet to receive direct transatlantic service, suggesting that liberalization alone does not lead to service level increases.     

Bivariate income distributions for assessing inequality and poverty under dependent samples

As indicators of social welfare, the incidence of inequality and poverty is of ongoing concern to policy makers and researchers alike. Of particular interest are the changes in inequality and poverty over time, which are typically assessed through the estimation of income distributions. From this, income inequality and poverty measures, along with their differences and standard errors, can be derived and compared. With panel data becoming more frequently used to make such comparisons, traditional methods which treat income distributions from different years independently and estimate them on a univariate basis, fail to capture the dependence inherent in a sample taken from a panel study. Consequently, parameter estimates are likely to be less efficient, and the standard errors for between-year differences in various inequality and poverty measures will be incorrect. This paper addresses the issue of sample dependence by suggesting a number of bivariate distributions, with Singh–Maddala or Dagum marginals, for a partially dependent sample of household income for two years. Specifically, the distributions considered are the bivariate Singh–Maddala distribution, proposed by Takahasi (1965), and bivariate distributions belonging to the copula class of multivariate distributions, which are an increasingly popular approach to modelling joint distributions. Each bivariate income distribution is estimated via full information maximum likelihood using data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey for 2001 and 2005. Parameter estimates for each bivariate income distribution are used to obtain values for mean income and modal income, the Gini inequality coefficient and the headcount ratio poverty measure, along with their differences, enabling the assessment of changes in such measures over time. In addition, the standard errors of each summary measure and their differences, which are of particular interest in this analysis, are calculated using the delta method.     

The New Deal and Modern Memory

The “Great Recession,” which began at year‐end 2007, was precipitated by plunging real estate values, followed by borrower defaults and financial crisis for the public and private institutions that supplied loanable funds to the mortgage market. With economic growth not yet returned to trend, three years on more than 9% of the American labor force remains unemployed. Current macroeconomic events, perhaps inevitably, have been compared to those of the Great Depression of 1929–1933, both in terms of severity and of the efficacy of the public policies adopted ostensibly to restore prosperity. In this article, I review the literature on the New Deal, paying particular attention to modern scholarship emphasizing the role of presidential politics and antibusiness political rhetoric in deepening and prolonging the Great Depression. The parallels between then and now suggest that the two economic contractions had similar causes and elicited equally counterproductive policy responses.
