This paper studies the consumption decisions of agents who face costs of acquiring, absorbing and processing information. These consumers rationally choose to only sporadically update their information and re-compute their optimal consumption plans. In between updating dates, they remain...

The paper considers a two-country model of overlapping generations heterogenous

The paper studies the determinants of income distribution and growth in an overlapping generations economy with heterogenous households. Our framework has the following main features: <OL> <LI>heterogeneity of consumers with respect to wealth and parental human capital; <LI>intergenerational transfers,...</li></li></ol>

The price elasticity of demand for credit has major implications for macroeconomics, finance, and development. We present estimates of this parameter derived from a randomized trial. The experiment was implemented by a consumer microfinance lender in South Africa and identifies demand curves...

This paper introduces a method for solving numerical dynamic stochastic optimization problems that avoids rootfinding operations. The idea is applicable to many microeconomic and macroeconomic problems, including life cycle, buffer-stock, and stochastic growth problems. Software is provided.

This paper presents a new approach to assess the role of price mismeasurement in the productivity slowdown. I invert the firm's investment decision to identify the embodied and disembodied components of productivity growth. With a Cobb-Douglas production function, output price mismeasurement...

We develop a simple analytical framework where the longevity of profit-maximizing firms requires costly resources. We show that a firm's longevity and value are positively related to the firm''s pricing power, cash reserves, honesty, and ratio of equity to debt financing.

The impact of combinations of frictions on investment activity is poorly understood. We develop a model of investment under financial frictions and irreversibility. We show that the possibility of encountering financial constraints in future raises irreversible investment today over that arising...

We build a heterogeneous life-cycle model which captures a large number of salient features of individual labor supply, by education, over the life cycle. The model provides an aggregation theory of individual labor supply, firmly grounded on micro evidence, and is used to study the aggregate...
