We address the long standing question of whether production factors are paid their marginalproducts. We propose a new approach that circumvents the need to specify productionfunctions and to compare marginal products to factor payments. Our approach is based on asimple equation that directly...

This paper presents a novel method for estimating the likely welfare effects of competition reforms for both current and new consumers. Using household budget survey data for 2015/16 for Ethiopia and assuming a reform scenario that dilutes the market share of the state-owned monopoly to 45...

Firms in developing countries often avoid paying taxes by making informal payments to tax officials. These bribes may raise the cost of operating a business, and the price charged to consumers. To decrease these costs, we designed a feedback incentive scheme for business tax inspectors that...

In a model with heterogeneous workers and both intensive and extensive margins of employment, we consider two systems of redistribution: a universal basic income, and a categorical unemployment benefit. Well-being depends on own-consumption relative to average employed workers' consumption, and...

We compare two systems of income redistribution: unemployment benefits (UB) and basic income (BI). First, for a simple utility function, with both intensive and extensive margins, the unemployed are likely better off with pure BI than pure UB, regardless of labour supply elasticity and wage...

We address the long standing question of whether production factors are paid their marginal products. We propose a new approach that circumvents the need to specify production functions and to compare marginal products to factor payments. Our approach is based on a simple equation that directly...

Previous research shows that firms shroud high add-on prices in competitive markets with naive consumers leading to inefficiency. We analyze the effects of regulatory intervention via educating naive consumers on equilibrium prices and welfare. Our model allows firms to shroud, unshroud, or...

The increasing use of demand-side management as a tool to reliably meet electricity demand at peak time has stimulated interest among researchers, consumers and producer organizations, managers, regulators and policymakers, This research reviews the growing literature on models used to study...

Evidence on behavior of experts in credence goods markets raises an important causality issue: Do "fair prices" induce "good behavior", or do "good experts" post "fair prices"? To answer this question we propose and test a model with three seller types: "the good" choose fair prices and behave...

Many information structures generate correlated rather than mutually independent signals, the news media being a prime example. This paper shows experimentally that in such contexts many people neglect these correlations in the updating process and treat correlated information as independent. In...
