Studying a principal-agent game in which the agent alone observes the state of the world and reports it, but the moral hazard is not reducible, shows that, if the principal uses all signals, then no solution exists, i.e. there is no contract that elicits truth-telling and motivates the agent to exert effort. When the principal does not use signals on the state of the world that seem irrelevant, a solution exists in which some of the ex post signals on outcome are not used, even though they obey the informativeness condition of Holmstrom (Bell Journal of Economics, 1979, 10, 74–91). 相似文献

In the framework of an incomplete financial market where the stock price dynamics are modeled by a continuous semimartingale (not necessarily Markovian), an explicit second-order expansion formula for the power investor’s value function—seen as a function of the underlying market price of risk process—is provided. This allows us to provide first-order approximations of the optimal primal and dual controls. Two specific calibrated numerical examples illustrating the accuracy of the method are also given. 相似文献

Key service innovation drivers in the tourism sector: empirical evidence and managerial implications 总被引:2,自引:2,他引:0

This study highlights the importance of market orientation and the use of information and communication technologies (ICT) as determinants of service innovation activity for companies in the tourism sector. In doing so, the study provides a means to classify companies as innovative or not. Using a sample of 100 Spanish firms from different branches of the tourism sector, we confirm and extend prior research. In particular, market orientation??especially a customer orientation??is critical for developing new services that lead to competitive advantages. In addition, ICT have a dual, direct, and indirect influence on service innovation. 相似文献

Liquidity risk and arbitrage pricing theory 总被引:2,自引:0,他引:2
Classical theories of financial markets assume an infinitely liquid market and that all traders act as price takers. This theory is a good approximation for highly liquid stocks, although even there it does not apply well for large traders or for modelling transaction costs. We extend the classical approach by formulating a new model that takes into account illiquidities. Our approach hypothesizes a stochastic supply curve for a securitys price as a function of trade size. This leads to a new definition of a self-financing trading strategy, additional restrictions on hedging strategies, and some interesting mathematical issues.Received: 1 November 2003, Mathematics Subject Classification:

Consider the following puzzle: If earnings management is harmful to shareholders, why don’t they design contracts that induce managers to reveal the truth? To answer this question, we model the shareholders–manager relationship as a principal–agent game in which the agent (the manager) alone observes the economic outcome. We show that the limited liability (LL) of the agent, defined as the agent’s feasible minimum payment, might explain the demand for earnings management by the principal. Specifically, when the LL level is high (low), a contract that induces earnings management may be less (more) costly than a truth-revealing contract. This finding offers a new explanation of the demand for earnings management. 相似文献

Static tradeoff theories, which do not explicitly treat the impact of transaction costs, do not explain the policy of asymmetry between frequent small debt transactions and infrequent large equity transactions. Nor do these theories explain why the debt ratio is allowed to wander a considerable distance from its alleged static optimum, or how much of a distance should be tolerated. We offer a class of diffusion models that mimic this behaviour in a stochastic-dynamic framework and are designed to optimize a financing strategy using any static tradeoff theory as input. The models developed reveal the determinants of the size and frequency of equity transactions and the range of values over which leverage variations are tolerated in four generic scenarios. They also yield a new formulation of the cost of capital that recognizes stochastic transaction costs and a penalty for deviation from any static-optimal leverage. Our class of models augments the pecking order theory, provides a flexible quantitative framework for its implementation as a decision tool, and facilitates the formulation of additional hypotheses for its empirical validation. Symmetrically, our results show the importance of dynamic factors in designing and interpreting empirical tests of static tradeoff theories. The results presented have important implications for the role played by static tradeoff theories in a stochastic-dynamic framework. One such implication is that the static-optimal leverage has no direct effect on the firm's leverage policy in this setting. The target leverage for refinancing transactions is different from the static-optimal leverage, and the mean leverage is generally different from both. As a consequence, the latter cannot be used to estimate the former. Another implication is that even when the mean leverage equals the static optimum, mean reversion is not an optimal behaviour and therefore not a legitimate test for the existence of a static tradeoff in a dynamic context. Still another implication is that wide variations in leverage ratios cannot be interpreted as evidence of leverage indifference. It follows that the pecking order theory is consistent with static tradeoff theories and does not require the assumption of leverage indifference. 相似文献

The financial crisis of 2008 was significantly influenced by housing, mortgage markets and mortgage-backed securities (MBS). The Federal Reserve (Fed) conducts temporary open market operations on a daily basis and frequently uses repos on MBS. With this daily interaction with MBS, we examine whether any signal about the impending financial crisis could have been seen in the Fed’s temporary open market operations. We identify four anomalous events in MBS temporary open market operations and examine those events for signals of the financial crisis. We find nothing in the four events that would have provided signals of the financial crisis. Instead, the common feature of the four events is an unusually large supply of MBS made available to the Fed for those day’s temporary open market operations. 相似文献

We analyze how the unique characteristics of real estate investment trusts (REITs) affect IPO lockup agreements from 1980
to 2006. The findings show that, unlike industrial IPOs, lockup periods for REIT IPOs do not cluster at 180 days, tend to
cover longer periods, and vary over time. Our results support the commitment device hypothesis instead of the signaling hypothesis.
That is, REIT managers tend to use lockup agreements to alleviate moral hazard problems and protect post-IPO investors rather
than to send signals to investors. Finally, contrary to previous studies, we find no significant negative abnormal returns
around the unlock date for the whole sample. The lack of aggressive sales by insiders and the fact that REITs are not backed
by venture capitalists can explain our finding. 相似文献

Few scholars would dispute the argument that mergers and acquisitions (M&As) are different in China and the United States,
but we know little about how they differ. This article reports one of the first studies that systematically compares and contrasts
how M&As differ in these two countries. While prior research on M&As tends to emphasize economic and financial explanations
while treating firms as atomistic actors severed from their institutional and network relations, we develop a new theoretical
framework based on relational, behavioral, and institutional perspectives. We not only consider firms as learning actors embedded
in network relations, but also compare and contrast their M&A patterns between China and the United States, two distinctive
institutional contexts. We find that both a firm’s structural hole position and its learning orientation (exploration/exploitation)
in alliances have direct and joint impacts on subsequent M&As. Further, such impacts differ across the two countries, due
to their institutional disparities. 相似文献

The analysis of poverty measures has been receiving increased attention in recent years. This paper contributes to the literature by developing percentile ratio estimators based on the pseudo empirical likelihood method. In practice, variances of poverty measures could be not expressible by simple formulae and consequently other techniques should be used in the variance estimation stage. Assuming percentile ratios, resampling techniques are investigated in this paper. A numerical example based on data from the Spanish Household Panel Survey is taken up to illustrate how suggested procedures can perform better than existing ones. The effect of a model-misspecification on the proposed estimators is also evaluated by using simulated populations. 相似文献
