Keeping it Fresh : Strategic Product Redesigns and Welfare

Blonigen, Bruce A. - 2013

Product redesigns happen across virtually all types of products. While there is substantial evidence that new varieties of goods increase welfare, there is little evidence on the effect of product redesigns. We develop a model of redesign and exit decisions in a dynamic oligopoly model (a la...

Entry, Pricing and Product Design in an Initially Monopolized Market

Davis, Steven J. - 2001

We analyze entry, pricing and product design in a model with differentiated products. Under plausible conditions, entry into an initially monopolized market leads to higher prices for some, possibly all, consumers. Entry can induce a misallocation of goods to consumers, segment the market in a...

Quality Ladders in the Theory of Growth

Grossman, Gene M. - 1989

We develop a model of repeated product improvements in a continuum of sectors. Each product follows a stochastic progression up a quality ladder. Progress is not uniform across sectors, so an equilibrium distribution of qualities evolves over time. But the rate of aggregate growth is constant....

The Method of Endogenous Gridpoints for Solving Dynamic Stochastic Optimization Problems

Carroll, Christopher D. - 2005

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

Optimal Monetary and Fiscal Policy : A Linear Quadratic Approach

Benigno, Pierpaolo - 2003

We propose an integrated treatment of the problems of optimal monetary and fiscal policy, for an economy in which prices are sticky and the only available sources of government revenue are distorting taxes. Our linear-quadratic approach allows us to nest both conventional analyses of optimal...

Vaccine Approvals and Mandates Under Uncertainty : Some Simple Analytics

Manski, Charles F. - 2014

Social interactions make communicable disease a core concern of public health policy. A prevalent problem is scarcity of empirical evidence that are informative about how interventions affect population behavior and illness. Randomized trials, which have been important to evaluation of...

Algorithms for Solving Dynamic Models with Occasionally Binding Constraints

Christiano, Lawrence J. - 1997

We describe and compare several algorithms for approximating the solution to a model in" which inequality constraints occasionally bind. Their performance is evaluated and compared" using various parameterizations of the one sector growth model with irreversible investment. We" develop...

A Model of the Optimal Complexity of Rules

Kaplow, Louis - 1992

. Greater complexity thus allows better control of behavior. But individuals may need to incur costs ex ante to determine how … models the effects of complexity on individuals' decisions to acquire information, choices about whether to act, and reports … of their actions to an enforcement authority. It considers how optimal sanctions depend on the complexity of rules and …
