Theoretically and experimentally, we generalize the analysis of acquiring a company (Samuelson and Bazerman 1985) by allowing for competition of both, buyers and sellers. Näıvety of both is related to the idea that higher prices exclude worse qualities. While competition of näıve buyers increases prices, competition of näıve sellers promotes efficiency enhancing trade. Our predictions are teste...

In the present paper, the issue of the existence of optimal barter steady states is addressed in a stationary overlapping generations model with many commodities and many different long-lived consumers. A general characterization of the individual endowments leading to an optimal barter steady state is obtained. The result, which is a generalization of Benveniste and Cass (1986), is obtained as...

Howard (1992) argues that the Nash bargaining solution is not Nash implementable, as it does not satisfy Maskin monotonicity. His arguments can be extended to other bargaining solutions as well. However, by defining a social choice correspondence that is based on the solution rather than on its realizations, one can overcome this shortcoming. We even show that such correspondences satisfy a str...

This article analyzes concerns about market power and inequality in a model with multiple sectors, heterogeneous abilities, endogenous labor supply, nonlinear income taxation. Proportional markups no profit dissipation have effect on the economy, policy that reduces nonproportional markup raises (lowers) welfare when it is higher (lower) than weighted average of other markups. With proportional...

در این پژوهش سعی می‌­شود مدلی برای شبیه‌­سازی چرخه عمر صنعت برق با استفاده از شبیه‌سازی عامل­بنیان ارائه شود، مدل، 5 عامل استخراج شد و شبیه­‌سازی به کمک نرم‌افزار Anylogic صورت پذیرفت. بهینه‌­سازی مدل چهار سناریو نظر خبرگان شد. سناریوی نخست، جذابیت نیروگاه گازی سیکل ترکیبی کاهش یافت بر دو دیگر افزوده نتیجه افزایش تولید آبی است که توجه کمبود منابع کشور به‌صرفه نیست. دوم ورود یک فناوری جدید میزان...

We study the problem of allocating objects when monetary transfers are possible. We are interested in mechanisms that allocate the objects in an e cient way and induce the agents to report their true preferences. Within the class of such mechanisms, rst we characterize egalitarian-equivalent mechanisms. Then, we add a bounded-de cit condition and characterize the corresponding class. Finally, w...

In this note we analyze whether a federal transfer system can be designed to increase welfare when state governments create political budget cycles. The results show how the federal government can counteract the welfare costs of these cycles, without hindering politicians from signaling their type, by announcing a transfer scheme to subsidize expenditures that voters do not consider when voting...

We show that for generic economies, every equilibrium admits Pareto improving monetary policy, even with multiple commodities per state. The main assumption is that asset incompleteness be intermediate, in that household heterogeneity does not exceed the number of assets present and absent. We argue this as a special case of the general framework in Turner (2003b) for proving the generic existe...
