We study how learning affects an uninformed monopolist's supply and investment decisions under multiplicative uncertainty in demand. The monopolist is uninformed because it does not know one of the parameters defining the distribution of the random demand. Observing prices reveals this...

We explore the role of firm-size asymmetry in a dynamic oligopoly where the consumption of specific capital is required in order to produce output. We find that when larger firms have a cost advantage due to their size, asymmetry leads to a decline in the supply of all firms, less capital...

We study the politico-economic equilibrium of a parametric version of the neoclassical growth model, uncovering the link between economic fundamentals, and (i) the level of government, and also (ii) the composition of government spending between public consumption and public infrastructure....

We introduce learning in a Brock–Mirman environment and study the effect of risk generated by the planner’s econometric activity on optimal consumption and investment. Here, learning introduces two sources of risk about future payoffs: structural uncertainty and uncertainty due to the...

Different family types may have a fixed flow of consumption costs related to subsistence needs. We use a survey approach in order to identify and estimate such a fixed component of spending for different families. Our method involves making direct questions about the linkup between aggregate...

We introduce learning in a Brock-Mirman environment and study the effect of risk generated by the planner's econometric activity on optimal consumption and investment. Here, learning introduces two sources of risk about future payoffs: structural uncertainty and uncertainty from the anticipation...

We build a tractable stylized model of external sovereign debt and endogenous international interest rates. In corrupt economies with rent-seeking groups stealing public resources, a politico-economic equilibrium is characterized by permanent fiscal impatience which leads to excessive issuing of...

Greece is at a decisive moment. It has to choose between defaulting and an economic program of structural reforms, privatization, efficient tax collection, and shrinking of the public sector. Unilateral suspension of debt payments would be an economic catastrophe for Greeks, resulting in deep...

Much analysis in macroeconomics empirically addresses economy-wide incentives behind consumer/investment choices by using insights from the way a single representative household would behave. Heterogeneity at the micro level can jeopardize attempts to back up the representative consumer...

Equivalence Scales are a tool for removing the heterogeneity of household sizes in the measurement of inequality, and affect poverty assessments and poverty lines. We address the disadvantage that poor households may suffer due to their reduced ability to share goods within the household. This...
