We consider a general equilibrium model with a production externality (e.g. pollution), where the regulator does not observe firm productivity shocks. We examine quantity (permit) regulation and price (tax) regulation. The quantity of permits issued by the regulator are independent of the productivity shock, since shocks are unobserved. Price regulation implies use of the regulated input is an ...

In this paper we study an alternating-offers bargaining model in which the set of possible utility pairs evolves through time in a non-stationary, but smooth manner. In general there exists a multiplicity of subgame perfect equilibria. However, we show that in the limit as the time interval between two consecutive offers becomes arbitrarily small, there exists a unique subgame perfect equilibri...

This article analyzes an asymmetric rent-seeking contest with free riding where valuation on the prize (rent) and effectiveness of rent-seeking effort may differ among agents and the victory of an agent may not exclude some agents other than the winner of the contest to consume the prize of the contest. After proving the unique existence of pure-strategy Nash equilibrium, this article examines ...

Rotten Kids with Bad Intentions We examine a "Rotten Kid" model (Becker 1974) where a player with social preferences interacts with an egoistic player. We assume that social preferences are intention-based rather than outcome-based. In a very general multi-stage setting we show that any equilibrium must involve mutually unkind behavior of both players, endogenously generating negative emotions ...

Transactions at non-equilibrium prices are “false trades”. Under standard assumptions, markets without false trading produce Pareto-efficient outputs. This paper demonstrates graphically the complications created when false trades occur, showing that quantities produced deviate from Pareto-efficient quantities except under unique conditions. In a general equilibrium framework, this spills over ...

In an integrated dynamic general equilibrium model of the economy and the ecosystem humans and other species compete for land and prey biomass. Each submodel exhibits a price-driven competitive allocation mechanism, and the endogenously determined habitat is either openly accessible or privately owned. In both scenarios specific corrective taxes or subsidies are needed to internalize ecosystem ...

We look at privatization in a general equilibrium model of a small, tariff-distorted, open economy. There is a differentiated good produced by both private and public sector enterprises. A reduction in government production in order to cut losses from such production raises the returns to capital and increases the tariff revenue, which are welfare improving. However, privatization also leads to...

Most studies that emphasize and encourage the shift towards a less regulated and financially open system rest on the premise of a prosperous growth prospect. Accordingly, interests have focused on growth models as a framework to understand and to analyze the effects of economic freedom. In this paper, we investigate the short-run characteristics of economic freedom. Using a stochastic general e...

Economic theory points out that immigration of even low-skilled immigrants may improve public finances in Western welfare states, and it is some times suggested that fiscal sustainability problems in Western countries caused by ageing populations could be solved by increasing immigration. We examine consequences of various immigration scenarios using the large-scale computable general equilibri...
