Uniqueness of stationary equilibria in a one-dimensional model of bargaining

We prove uniqueness of stationary equilibria in a one-dimensional model of bargaining with quadratic utilities, for an arbitrary common discount factor. For general concave utilities, we prove existence and uniqueness of a “minimal” stationary equilibrium and of a “maximal” stationary equilibrium. We provide an example of multiple stationary equilibria with concave (nonquadratic) utilities.     

The business cycle with nominal contracts

Summary In this paper we study the quantitative implications of nominal wage contracts for business cycle fluctuations. We address this issue using a model economy based on the neoclassical growth model supplemented by the assumption that cash is needed to purchase goods. We consider a variation of the standard recursive competitive equilibrium concept that is intended to capture the important features of wage contracting. We use this equilibrium construct to address three issues. First, we consider whether monetary shocks, propagated by nominal contracts, constitute a viable alternative to technology shocks as a source of aggregate fluctuations. Our results suggest that, while monetary shocks and nominal rigidities succeed in causing output volatility of the required magnitude, the resulting data have properties that are inconsistent with several key features of U.S. data. Second, we consider how the behavior of the economy varies with contract length. We find that the volatility induced by both monetary and technology shocks increases sharply with contract length. Finally we consider how much rigidity would be necessary to match the volatility of U.S. output. We find that only a very small amount of rigidity would be necessary to cause output volatility of the magnitude observed.We have received helpful comments from David Chapman, Paul Gomme, Jeremy Greenwood, Gary Hansen, Michael Keane, Tim Kehoe, Lee Ohanian, Edward Prescott, and Warren Weber.

农民工返乡创业发展规律、制约瓶颈与对策思考——基于湖北省15县67名返乡创业者的纪实调查

返乡创业是农民工对输出地与输入地的投资成本与效益比较后的理性选择。农民工返乡创业主要以中小企业或个体的多行业经营分布为主。农民工返乡“创业潮”形成的两个阶段在兴办企业的资金来源、产业结构和销售渠道等方面差异较大。由于农民工自身素质和条件以及外在环境制约着民工的创业发展,因此应从农民工自身素质的提高和创业环境的优化两方面着手促进农民工返乡创业。

Performance deviations and acquisition premiums: The impact of CEO celebrity on managerial risk‐taking

Research summary: This article draws on identity control theory and a study of acquisition premiums to explore how CEO celebrity status and financial performance relative to aspirations affect firm risk behavior. The study finds that celebrity CEOs tend to pay smaller premiums for target firms, but these tendencies change when prior firm performance deviates from the industry average returns, thereby leading these CEOs to pay higher premiums. The study also finds that the premiums tend to be even larger when celebrity CEOs have more recently attained celebrity status. Taken together, these findings contribute to identity control theory and CEO celebrity literatures by suggesting that celebrity status is a double‐edged sword and that the internalization of celebrity status by CEOs strongly influences the decision‐making of CEOs. Managerial summary: The purpose of this article is to examine how CEO celebrity status and financial performance relative to aspirations affect the size of acquisition premiums. The study finds that celebrity CEOs tend to pay smaller premiums for target firms. However, when celebrity CEOs' prior firm performance is either better or worse than the industry average, these CEOs pay higher premiums. This situation is exacerbated when the CEO has only recently been crowned a celebrity. In effect, these CEOs feel great pressure to match the inflated performance expectations that come with celebrity status. These findings suggest that being a celebrity is a double‐edged sword. The implication here is that CEOs who have recently been crowned a celebrity should be aware of these pressures and cope accordingly. Copyright © 2015 John Wiley & Sons, Ltd.
