This experimental study examines whether the content of information and the timing of its dissemination affects firms’ market power. We construct laboratory markets that capture the key features of a price-setting, differentiated goods, duopoly model analyzed by Anderson and Renault (2000). Consumers must typically incur a search cost in order to obtain any information, but a fraction of the co...

the main goal of this study was to investigate the way of affecting of water in production of cucumber. from aspect of econometrics, mutual relationships of production function and expenses have been analyzed in which translog cost function has been used. this function has been estimated using the conditional input demand functions, the shefard theorem, chemical fertilizer, animal fertilizer, l...

(*See endnotes for complete contributor biographies.) Virtually all aspects of economic activity–individual consumption, business investment, and government spending–affect greenhouse gas emissions and, hence, the global climate. An effective climate change policy would change the decision calculus for these activities to promote more ef1⁄2cient generation and use of energy, lower carbon-intens...

Standard lessons from economics tell us that an externality creates inefficiency, and that this inefficiency can be removed by internalizing the externality. This papers considers how successfully these lessons can be extended to intergenerational externalities such as emissions of greenhouse gas. For intergenerational externalities, the standard lessons involve comparisons between states whose...

Consumers sometimes make choices that impose greater external costs on those who do not make the same choice. This paper examines how the selectivity of negative externalities in such situations affects the competitive equilibrium and the desirability of an externality-reducing public policy. Selective negative externalities create network externalities, but outcomes may differ greatly from typ...

An open puzzle for climate-policy analysis is how policies could be made sensitive to climate change impacts spanning over centuries while keeping the shorterterm macroeconomic policies connected to the descriptive facts. We develop a tractable general-equilibrium model for climate-economy interactions with timedeclining pure discounting. The model resolves the puzzle: preferences over longterm...

It is difficult to resolve the global warming free-rider externality problem by negotiating n different quantity targets. By contrast, negotiating a single internationally binding minimum carbon price (the proceeds from which are domestically retained) counters self-interest by incentivizing agents to internalize the externality. The model of this article indicates an exact sense in which each ...
