Studies of transactions surrounding stock split ex-dates often conclude that splitting firms either experience a decline or an improvement in their stock's liquidity, based on independent measures of trading costs and trading activity. In contrast, our evidence suggests that splits from outside into what often is deemed to be the optimal stock price range of $10.00 to $39.99 are nonevents for market makers: The spread-setting behavior of the market does not change after a split. Our analysis accounts for the interdependencies between bid-ask spreads and market microstructure effects and distinguishes between optimal and all other splitting firms.  相似文献

One role of accounting is to discipline softer (more manipulable) sources of information. We use a principal-agent model of hidden actions and hidden information to study this role. In our model, there is both a verifiable signal (a publicly observed output) and an unverifiable signal (a productivity parameter privately observed by the agent). In a one-period setting, the optimal contract does not make use of the agents report on the private signal. However, when the output is tracked over two periods, the agents communication can be valuable. This reversal of results suggests uncovering the disciplining role of accounting may require a long-term perspective.JEL Classification: D82, M41  相似文献

This paper examines the intraday bid-ask bounce in Deutschemark and Japanese yen futures prices. The intraday Markovian bid-ask bounce process, which leads to a desirable equilibrium condition of reaching a bid or an ask transaction type with equal chances, is identified. A second-order Markov chain transition matrix model is used to derive a generalized estimator of bid-ask spreads in the foreign exchange futures market. It incorporates the conditional probabilities of a subsequent transaction being the same type as the current transaction's () and that of the next transaction being the same as the current type but different from the previous type (). The specification is {-Cov(P t ,P t+1 )/[(1–)(–)]}1/2. The empirical results show that the average implied bid-ask spread is about $10, which is less than one tick's value of $12.50. It is also found that spreads are higher at the beginning and end of the trading day than the rest of the day, reflecting the uncertainty due to information flows and overnight inventory carrying costs, respectively.  相似文献

In the presence of transaction cost, the perfect timing strategy which holds stocks in a period with positive excess return and holds cash in a period with negative excess return is not necessarily perfect. Using the optimal growth criterion, this paper derives the truly perfect timing strategy which can achieve the maximum long term growth. It is found that such a perfect timing strategy can achieve a much higher annual return than the perfect timing strategy under reasonable transaction cost. Also, it can achieve a return of over 80% when a review period is as short as a day and when transaction cost is low. Using the truly perfect timing strategy as a benchmark, the likely gains from imperfect timing can be more accurately assessed. For a less frequent review schedule, a market timer needs a very high correct prediction probability in order to be at par with the buy-and-hold strategy. However, the needed correct prediction probability is much less when the review schedule is more frequent. Also, the correct prediction probability needed to be at par with the buy-and-hold strategy increases with the transaction cost.  相似文献

We use a unique data set to study how U.K. banks deal with financially distressed small and medium-sized companies under a contractualist bankruptcy system. Unlike in the U.S., these procedures limit the discretion of courts to strict enforcement of debt contracts, without any dilution of creditors claims. We show that lenders and borrowers select a debt structure that avoids some of the market failures often attributed to a contractualist system. Collateral and liquidation rights are highly concentrated in the hands of the main bank, giving it a dominant position in restructuring or liquidating a defaulting firm. There is little litigation, and no evidence of co-ordination failures or creditors runs. However, there is some evidence that the banks dominance makes it lazy in monitoring, relying heavily on the value of its collateral in timing the bankruptcy decision.  相似文献

Summary. Experiments were conducted on an asset with the structure of an option. The information of any individual is limited, as if only the direction of movement of the option value known for a single period without information of the value from when movement was initiated. However, if all information of all insiders were pooled, the value of the option would be known with certainty. The results are the following: (1) Information becomes aggregated in the prices as if fully informative rational expectations operated; and (2) The mechanism through which information gets into the market is captured by a path dependent process that we term The Fundamental Coordination Principle of Information Transfer in Competitive Markets. The early contracts tend to be initiated by insiders who tender limit orders. The emergence of bubbles and mirages in the markets are coincident with failures and circumstances that prevent the operation of the Fundamental Principle.The financial support of the national science foundation and the Caltech Laboratory for Experimental Economics and Political Science are gratefully acknowledged.

Optimal Loan Interest Rate Contract Design   总被引:1,自引:0,他引:1  
This paper analyzes optimal loan interest rate contracts under conditions of risky, symmetric information for one-period (static) and multi-period (dynamic) models. The optimal loan interest rate depends upon the volatility of, and co-variation among the market interest rate, borrower collateral, and borrower income, as well as the time horizon and the risk preferences of lenders and borrowers. For a risk-averse borrower with stochastic collateral, variable interest rate contracts are, in general, Pareto optimal. For plausible assumptions, the optimal loan interest rate for the multi-period model often exhibits muted responses to changes in market interest rates, making fixed rate loans a reasonable approximation for the optimal loan. Hence, in the absence of optimal contracts, long-term (short-term) borrowers tend to prefer fixed rate (variable) contracts.  相似文献

Summary. Having been crafted to welcome a new scientific journal, this paper looks forward but requires no special prerequisite. The argument builds on a technical wrinkle (used earlier but explained here fully for the first time), namely, the authors grid-bound variant of Brownian motion B(t). While B(t) itself is additive, this variant is a multiplicative recursive process the author calls a cartoon. Reliance on this and related cartoons allows a new perspicuous exposition of the various fractal/multifractal models for the variation of financial prices. These illustrations do not claim to represent reality in its full detail, but suffice to imitate and bring out its principal features, namely, long tailedness, long dependence, and clustering. The goal is to convince the reader that the fractals/multifractals are not an exotic technical nightmare that could be avoided. In fact, the authors models arose successively as proper, natural, and even unavoidable generalization of the Brownian motion model of price variation. Considered within the context of those generalizations, the original Brownian comes out as very special and narrowly constricted, while the fractal/multifractal models come out as nearly as simple and parsimonious as the Brownian. The cartoons are stylized recursive variants of the authors fractal/multifractal models, which are even more versatile and realistic.This revised version was published online in January 2005 with corrections to the Cover date.  相似文献

Balance Sheets, the Transfer Problem, and Financial Crises   总被引:7,自引:0,他引:7  
In a world of high capital mobility, the threat of speculative attack becomes a central issue of macroeconomicpolicy. While first-generation and second-generation models of speculative attacks both have considerablerelevance to particular financial crises of the 1990s, a third-generation model is needed to make sense of thenumber and nature of the emerging market crises of 1997-98. Most of the recent attempts to produce such amodel have argued that the core of the problem lies in the banking system. This paper sketches another candidatefor third-generation crisis modeling—one that emphasizes two facts that have been omitted from formal modelsto date: the role of companies' balance sheets in determining their ability to invest, and that of capital flows inaffecting the real exchange rate.  相似文献

Unit root, co-integration, and Granger Causality are used to test specification of a generalized time series model of mortgage choice. Unit root tests determine that both the fixed-adjustable spread (FAsp) and the proportion of ARM originations (AP) are first difference stationary. The cointegrating vector between FAsp and AP was found to be weak, raising questions regarding their long-term relationship. Causality tests determined that ARM originations Granger causes the fixed-adjustable mortgage spread (APFAsp) rather than FAspAP. This result suggests that mortgage originators adjust the current FAsp spread based on last periods allocation. The coefficient vector for this specification was unstable and became increasingly negative during the 1980s.  相似文献

The paper analyzes the role of agency driven takeover activity. The analysis shows that takeovers can play an important role in reducing agency costs even though the gains from the corporate restructuring that follows the takeovers are zero, which counters existing models of agency driven takeover activity. The model can therefore form the basis for deriving empirical predictions which discriminate between the agency paradigm and the corporate restructuring paradigm of takeover activity. Negative post-merger performance (Agrawal et al., 1992), which is inconsistent with corporate restructuring is consistent with this model, and that takeover targets' investment levels are below or at the average (Servaes 1994), which is inconsistent with the free cash flow theory is also consistent with this model.  相似文献

The effects on real estate development of shore-protection efforts that lower erosion rates and storm hazards are both controversial and difficult to detect. A simple theoretical model indicates that shore protection is likely to tilt development from areas a few hundred feet inland toward beachfront property. A modified repeat-sale house price index is used to measure price appreciation rates to the waters edge. We are able to formulate an extremely sensitive empirical test for a tilt in rates of house-price appreciation implied by a tilt in development. Surprisingly, we find no significant evidence that shore-protection efforts have produced additional beachfront development in the Florida counties studied. The method used in this article is quite general and could be used in a number of applications where an environmental effect impacts real estate differentially over space.  相似文献

Residual Income and Value-Creation: The Missing Link   总被引:2,自引:0,他引:2  
This paper extends the residual income literature to provide a framework for the use of residual income in performance measurement, applicable in value-based management. It shows that, under a simple initializing assumption, an accounting-free measure of excess value created over a multi-period interval can be written entirely in terms of (i) within-interval realized residual incomes and (ii) end-of-interval expected future residual incomes, both appropriately adjusted for the time value of money. It also shows that, when the simple initializing assumption is relaxed, excess value created can be expressed in terms of excess residual incomes, measured by comparison with expectations as at the beginning of the multiperiod interval.  相似文献

We provide an economic analysis of forum selection in international business contracts. International business contracts or multi-state transactions within federally structured countries might be subject to more than one sovereign adjudication system. In case of conflict between the transacting parties, the appropriate tribunal must be identified. We examine the question of business firms' optimal choice of the forums to adjudicate future business disputes. We extend the investment model approach to litigation by applying a portfolio theory type analysis. We show that firms that prefer higher expected income and lower income volatility are better off diversifying the forums under which they litigate business disputes. This stands in contrast to real-world business practice that consistently shows a clear preference to selecting the home court and legal system to settle international business disputes. In a fraction of the cases, both parties gain by selecting a certain forum, because of specialization for example, and it becomes optimal to ignore diversification. In most cases, however, the relevant factors that affect forum selection are zero sum and priced ex ante, court bias, for example. Once priced, there is no incentive to disregard diversification. We hypothesize that, in addition to specialization, factors such as managerial moral hazard explain the real-world behavior of firms: managers are less likely to be blamed, ex post, for choosing the home court. We suggest that, as international barriers decline and international trade grows, firms will diversify the forums in which they adjudicate international business disputes.  相似文献

Lee, Shleifer, and Thaler (1991) argue that the irrational noise trader model of DeLong, Shleifer, Summers, and Waldmann (1990) ... is consistent with the published evidence on closed-end fund prices. ... However, Lee, Shleifer, and Thaler provide no indication of how much of the variability of a closed-end fund's discounts and premiums is due to such investor sentiment. Using the signal extraction technique of French and Roll (1986) to measure noise, this article estimates that on average only 7 percent of the variance of a standardized measure of weekly changes in discounts and premiums can be attributed to noise-trading activity. Investor sentiment, therefore, seems to account for very little of a closed-end fund's discount and premium variability over time.  相似文献

In this paper we consider a continuous time model for the security price with the time-dependent volatility. It is shown that the non-normality and non-linear dependency of the short-term return, the major characteristics observed on many financial assets, can be incorporated into our model. In order to evaluate the option price formula on the model we propose a nonparametric predictor for the volatility function without reference to a specific functional form. We examine the so-called continuous record asymptotics and show that the proposed predictor is asymptotically minimax for a wide class of the volatility functions. One of the most important results is that the application of the Black-Scholes method can be justified by plugging the proposed predictor in the standard Black-Scholes formula even if the volatility changes over time.  相似文献

Getting the Unemployed Back to Work: The Role of Targeted Wage Subsidies   总被引:2,自引:1,他引:1  
This paper examines alternative approaches to wage subsidy programmes. It does this in the context of a recent active labour market reform for the young unemployed in Britain. This New Deal reform and the characteristics of the target group are examined in detail. We discuss theoretical considerations, the existing empirical evidence and propose two strategies for evaluation. The first suggests an ex-post trend adjusted difference in difference estimator. The second, relates to a model based ex-ante evaluation. We present the conditions for each to provide a reliable evaluation and fit some of the crucial parameters using data from the British Labour Force Survey. We stress that the success of this type of labour market programmes hinge on dynamic aspects of the youth labour market, in particular the pay-off to experience and training.  相似文献

A representative individual lives for two periods; works when young and depends on savings and a government operated social security system when old—the returns on both sources of income, when old, are random. Due to administrative problems the returns to savings are observed with some measurement error. Two alternative consumption tax systems are considered; the Registered Asset Treatment (RAT) and the Non-Registered Asset Treatment (NRAT). The advantage of the RAT is that it can perform a social insurance role while the disadvantage is that it imposes measurement error risk. Correlation between the random return on saving and its measurement error can provide a risk-hedging role that can be further strengthened by the RAT version. The NRAT version neither provides social insurance nor imposes measurement error risk. Both tax systems hedge against the uncertainties in the social security system. The taxpayer engages in precautionary saving in response to future uncertainty.  相似文献

In this paper, the concept of absolutely riskier than is introduced to generalize Gollier's (Journal of Economic Theory, 66, 522–535) necessary and sufficient conditions for the comparative statics of a change in risk for risk averters. The restrictive assumption that the payoff function is monotonic in the risk is relaxed. The policymaker's choice problem, the newsboy problem, and a farmer's example are used to illustrate how easily the monotonicity assumption is violated. Finally, some important properties of the concept of absolutely riskier than, such as its relation with the concept of second-order stochastic dominance, are illustrated using the farmer's example.  相似文献

Dual VATs and Cross-Border Trade: Two Problems, One Solution?   总被引:1,自引:0,他引:1  
In recent years, two distinct but related questions have been raised with respect to value-added taxes (VATs). Concern has been expressed over whether it is desirable or even possible for both national and subnational governments in federal countries such as India, Argentina, and Russia to impose VATs. One reason for thinking that such subnational VATs are unlikely to be workable on a destination basis is the problem of cross-border trade. Of course, this same problem also arises within the European Union, where there is no EU VAT. Drawing upon Canadian experience, we argue that not only is it possible to have two-tier or dual VATs on a destination basis in a single country but that the existence of dual VATs may help deal with some of the problems of cross-border trade.  相似文献
