Credible implementation of climate change policy, consistent with the 2 °C limit, requires a large proportion of current fossil-fuel reserves to remain unused. This issue, named the Carbon Bubble, is usually presented as a required asset write-off, with implications for investors. We embed the Carbon Bubble in a macroeconomic model exhibiting a financial accelerator: if investors are leveraged, then the Carbon Bubble might precipitate a fire-sale of assets across the economy, and generate a large and persistent fall in output and investment, impairing the economy's ability to invest in the zero carbon assets it needs to produce output in the post-climate-transition world. We find a role for macroeconomic policy protecting investors' balance sheets in mitigating the macroeconomic effects of the Carbon Bubble, and enhancing welfare. 相似文献

We model firms' quality disclosure and pricing in the presence of cursed consumers, who fail to be sufficiently skeptical about undisclosed quality. We show that cursed consumers are exploited in duopoly if firms are vertically differentiated, if there are few cursed consumers, and if average product quality is high. Three common consumer protection policies that work under monopoly, that is, mandatory disclosure, third party disclosure and consumer education, may all increase exploitation and decrease welfare. Even where these policies improve welfare, they often lead to a reduction in consumer surplus. Our conclusions hold in extensions with endogenous quality and horizontal differentiation. 相似文献
This paper studies the effects of mobilization for war on the development of fiscal capacity and the values of tax compliance (tax morale). We propose a dynamic setting where governments may invest resources to improve the efficiency of the fiscal apparatus and the citizens' tax morality in order to raise the necessary revenues for the defense against a threat (external or internal), and parents optimally choose to transmit their preferences of tax compliance to children. Despite fiscal capacity and tax morale are initially substitutes, we show how a dynamic complementarity may arise in equilibrium from a more efficient transmission of the values of tax compliance in countries with high fiscal capacity, and this may explain why they tend to move together over time. Under reasonable conditions, we obtain that the effect of a higher threat of war on the steady-state level of the culture of tax compliance is negative when fiscal capacity is relatively low, and positive when the latter is large. We show cross-country evidence based on war frequency, fiscal capacity, and tax morale that is consistent with the results of our theory. 相似文献
Airport runways, radio spectrum, and hospital beds are resources with capacity limits used to provide multiple services with specific capacity requirements in separate markets, which contribute to recover capacity investment costs. A welfare-maximizing and (possibly) budget-constrained firm, whose operating costs significantly increase as total capacity use presses against capacity, chooses prices and capacity. When the equilibrium capacity is reached, second-best Ramsey prices must be adjusted, and mark-ups on marginal costs may be higher for services with higher demand elasticities, if they intensively use capacity. Moreover, for a given output vector, the firm invests more than in first best. Instead, the equilibrium capacity may be first best when there is excess capacity to reduce operating costs and thus improve welfare. Our model can be used as a benchmark to evaluate the efficiency of market mechanisms for resource allocation and pricing, or when market mechanisms are not adopted.

This article examines the influence exerted by the Federal Reserve chair on monetary policy decisions. We construct a voting model where the chair selects the proposal that is initially put to a vote but is subject to an acceptance constraint that incorporates the preferences of the median Federal Open Market Committee (FOMC) member and the probability of counterproposals. The model is estimated by maximum likelihood using real-time data from FOMC meetings. Results for all chairs in our sample show that the chair's proposal is the result of a compromise, reflecting a stable balance of power within the FOMC. 相似文献

We study a multiplayer stochastic differential game, where agents interact through their joint price impact on an asset that they trade to exploit a common trading signal. In this context, we prove that a closed-loop Nash equilibrium exists if the price impact parameter is small enough. Compared to the corresponding open-loop Nash equilibrium, both the agents' optimal trading rates and their performance move towards the central-planner solution, in that excessive trading due to lack of coordination is reduced. However, the size of this effect is modest for plausible parameter values. 相似文献
