In practice, heterogeneously informed speculators combine private information about multiple stocks with information in prices, taking into account how their trades influence the inferences of other speculators via prices. We show how this speculation causes prices to be more correlated than asset fundamentals, raising price volatility. The covariance structure of asset fundamentals drives that of prices, while the covariance structure of liquidity trade drives that of order flows. We characterize how speculator profits vary with the distributions of information and liquidity trade across assets and speculators, and relate the cross‐asset factor structure of order flows to that of returns.  相似文献

A Theory of Takeovers and Disinvestment   总被引:4,自引:0,他引:4  
We present a real‐options model of takeovers and disinvestment in declining industries. As product demand declines, a first‐best closure level is reached, where overall value is maximized by closing the firm and releasing its capital to investors. Absent takeovers, managers of underleveraged firms always close too late, although golden parachutes may accelerate closure. We analyze the effects of takeovers of under‐leveraged firms. Takeovers by raiders enforce first‐best closure. Hostile takeovers by other firms occur either at the first‐best closure point or too early. Closure in management buyouts and mergers of equals happens inefficiently late.  相似文献

Earlier studies on the stability of monetary unions show that an inflation‐targeting central bank imposes strict budgetary requirements on fiscal policy to obtain a unique stable equilibrium. Failure of only one fiscal authority to meet these requirements already results in nonexistence of equilibrium. Nevertheless, it might prove useful to temporarily depart from such requirements in order to absorb country‐specific shocks. We show that such departures are feasible if fiscal authorities commit to switch to more sustainable fiscal regimes in the future. Debt devaluation and fiscal bailouts may also broaden the range of policy stances under which monetary unions are stable.  相似文献

In this article we study the evolution of marriage seasonality in relation to economic change, particularly connected to changes in labour supply and work intensity of the kind implied by the ‘industrious revolution’. The focus is on southern Sweden in 1685–1894, which was a period of agricultural transformation and early industrialization, when we would expect to see an increase in work intensity. The analysis is based on about 120,000 marriages from 117 different parishes. The analysis shows that the seasonality of marriage changed dramatically over time, from a classic grain production pattern, with a marriage peak in late spring and a marriage trough at harvest time, to a much more even seasonality, although with the appearance of a very strong peak in December. This change affected rural rather than urban areas, and was present regardless of differences in institutional settings, and for almost all occupational groups below the elite. The changed seasonality pattern is consistent with increasing work intensity over the year, leaving only the weeks around Christmas as a low season. In addition to the increase in work intensity, the privatization of marriage and the availability of time and resources were also important factors in the changing seasonality pattern.  相似文献

The purpose of this study is to investigate the governance questions that board members in public service organizations ask as they go about fulfilling their responsibilities for the oversight of executive compensation. We investigate the usage and perceived importance by board members of the 24 questions proposed by the Canadian Institute of Chartered Accountants that directors should ask about executive compensation. The study is based on a usable sample of 47 board members from public service organizations who attended a Canadian director training program. Our results suggest that the recommended executive compensation governance questions are not being asked with the same frequency or considered equally important by board members of public service organizations. Furthermore, the correlation between a question’s usage frequency and its perceived importance was not perfect. However, there appears to be a significantly positive relationship among the number of executive compensation governance questions asked and selected elements of a board’s governance structure.  相似文献

The development of the high‐pressure expansive engine represented a watershed in the evolution of steam power technology, allowing the attainment of major fuel economies. In Britain, Cornish engineers took the lead in the exploration of this specific technological trajectory. Notwithstanding its superior fuel efficiency was immediately widely discussed, the high‐pressure expansive engine did not find widespread application in other steam‐using regions (in particular in Lancashire), where the Watt low‐pressure engine continued to be the favourite option. This article provides a reassessment of the factors accounting for the precocious adoption of the high‐pressure steam engine in Cornwall and for its delayed fortune in the rest of Britain.  相似文献

We introduce a model of monetary policy with downward nominal wage rigidities and show that both the slope and curvature of the Phillips curve depend on the level of inflation and the extent of downward nominal wage rigidities. This is true for the both the long‐run and the short‐run Phillips curve. Comparing simulation results from the model with data on U.S. wage patterns, we show that downward nominal wage rigidities likely have played a role in shaping the dynamics of unemployment and wage growth during the last three recessions and subsequent recoveries.  相似文献

We develop a dynamic agency model in which payout, investment, and financing decisions are made by managers who attempt to maximize the rents they take from the firm, subject to a capital market constraint. Managers smooth payout to smooth their flow of rents. Total payout (dividends plus net repurchases) follows Lintner's (1956) target adjustment model. Payout smooths out transitory shocks to current income and adjusts gradually to changes in permanent income. Smoothing is accomplished by borrowing or lending. Payout is not cut back to finance capital investment. Risk aversion causes managers to underinvest, but habit formation mitigates the degree of underinvestment.  相似文献

This article attempts to clarify our understanding of the everyday use of the word “fair” as we apply it to economic behavior. I first examine the decomposition of fair into its semantic primitives and discuss implications of recent research that indicates that the word is one‐to‐one untranslatable into any other language, that is, the concept of fair is distinctly Anglo. I also make a Wittgensteinian appeal to context and human sociality as an indispensable tether for what we mean by a fair experience and what we know, epistemologically speaking, about fairness. The principal implication of this is that rules that guide fair behavior are not located in an individual's private utility function but instead reside in the connections that the individual has to his cultural environs.  相似文献
