OLS estimation of an impulse-indicator coefficient is inconsistent, but its variance can be consistently estimated. Although the ratio of the inconsistent estimator to its standard error has a tdistribution, that test is inconsistent: one solution is to form an index of indicators. We provide Monte Carlo evidence that including a plethora of indicators need not distort model selection, permitti...

this paper evaluates the real exchange rate fluctuations and uncertainties resulting from it, in the iranian economy. for this purpose, at first indirect effect of real exchange rate uncertainties on economic growth through foreign investment, private investment and exports are expressed, then the real exchange rate uncertainties and its relationship with economic growth and final pattern of in...

We study the impact of group-based cognitive behavioral therapy (CBT ) for individuals selected from general population poor households in rural Ghana (N = 7,227). Results one to three months after program show strong impacts on mental and perceived physical health, socioemotional skills, economic self-perceptions. These effects hold regardless baseline distress. argue that this is because CBT ...

The long-term trends of urbanization suggest: not only have more cities formed, but the leading metropolises have grown larger, with a number of peripheral subcenters developing over time. Conventional models of urban growth are limited, in that commuting cost and congestion eventually result in decreasing returns in a monocentric city as population becomes very large. We construct a general-eq...

In this paper, we study adaptive nonparametric regression estimation in the presence of conditional heteroskedastic error terms. We demonstrate that both the conditional mean and conditional variance functions in a nonparametric regression model can be estimated adaptively based on the local profile likelihood principle. Both the one-step Newton-Raphson estimator and the local profile likelihoo...

This paper estimates the impact of first nationwide e-commerce expansion program on rural households. To do so, we combine a randomized control trial with new survey and administrative microdata. In contrast to existing case studies, find little evidence for income gains producers workers. Instead, are driven by reduction in cost living minority households that tend be younger, richer, more rem...

Bergstrom showed that a necessary condition for a Pareto optimum with non-paternalistic altruism is classification as a selfish Pareto optimum. This paper shows that Bergstrom’s result does not generalize to the benefit-cost analysis of generic changes in public goods. There may exist good projects that will be rejected by a selfish-benefit cost test, a selfish test error. Selfish test error is...

How do workers make wage comparisons? Both an experimental study and an analysis of 16,000 British employees are reported. Satisfaction and well-being levels are shown to depend on more than simple relative pay. They depend upon the ordinal rank of an individual’s wage within a comparison group. ‘Rank’ itself thus seems to matter to human beings. Moreover, consistent with psychological theory, ...

Traditional tools of welfare economics identify the envy-related welfare loss from conspicuous consumption only under very strong assumptions. Measured income and life satisfaction offers an alternative for estimating such consumption externalities. The approach is developed in the context of luxury car consumption (Ferraris and Porsches) in Switzerland. Results from household panel data and fi...

Does Relative Income Matter for the Very Poor? Evidence from Rural Ethiopia We studied whether relative income has an impact on subjective well-being among extremely poor people. Contrary to the findings in developed countries, where relative income has shown a significant and negative impact on subjective well-being, we cannot reject the hypothesis that relative income has no impact on subject...
