Illiquid nominal government bonds are shown to have two opposing effects on welfare. First, the relatively poor choose to top-up money balances for future consumption by purchasing nominal bonds at a discount. The wealth distribution becomes more centered with a smaller consumption deviation from the first best. Second, the higher inflation tax on monetary wealth to finance interest payments makes money less valuable, so that the quantity of output produced in exchange for money decreases. The trade-off between the welfare-enhancing effect on wealth distribution and the distortionary effect on output implies the socially optimal discount rate and liquidity.  相似文献

Endogenous labor supply decisions are introduced in an equilibrium model of limited insurance against idiosyncratic shocks. Unlike in the standard case with exogenous labor (e.g. [Aiyagari, S.R., 1994. Uninsured idiosyncratic risk and aggregate saving. Quarterly Journal of Economics 109, 659-684; Huggett, M., 1997. The one-sector growth model with idiosyncratic shocks: steady states and dynamics. Journal of Monetary Economics 39, 385-403]), labor supply is likely to be lower than under complete markets. This is due to an ex post wealth effect on labor supply (rich productive agents work fewer hours) that runs counter the precautionary savings motive. As a result, equilibrium savings and output may be lower under incomplete markets. It is also found that long-run savings remain finite even when the interest rate equals the inverse of the discount factor.  相似文献

This paper examines the effect of prior investment experience in specific industries on subsequent investment decisions. Using households’ trading records from a large discount broker between 1991 and 1996, I find that prior success in a given industry increases the likelihood of subsequent purchases in the same industry. The effect is stronger for more recent experiences and for less sophisticated or diversified investors, and it is not wealth enhancing. The results suggest investors categorize industries at a highly resolved level, finer than the Fama–French ten-industry classification. Similar effects are also apparent for size- and value-based categories but at smaller magnitudes.  相似文献

Do behavioral biases of executives matter for corporate investment decisions? Using segment‐level capital allocation in multisegment firms (“conglomerates”) as a laboratory, we show that capital expenditure is increasing in the expected skewness of segment returns. Conglomerates invest more in high‐skewness segments than matched stand‐alone firms, and trade at a discount, which indicates overinvestment that is detrimental to shareholder wealth. Using geographical variation in gambling norms, we find that the skewness‐investment relation is particularly pronounced when CEOs are likely to find long shots attractive. Our findings suggest that CEOs allocate capital with a long‐shot bias.  相似文献

The typical financial management text states that management's objective should be to maximize owners’ wealth. The same texts then economic ordering quantity (EOQ) as a method for analyzing inventory problems without typing EOQ back to wealth maximization. This article shows algebraically that EOQ is not entirely consistent with the assumed objective. However, by simulation, EOQ is shown to yield answers that are sufficiently accurate for practical application.  相似文献

This study examines the effect of initiating discount and no discount dividend reinvestment plans on shareholder wealth. The results show a negative response to DRP announcements, which is significantly smaller than that found in studies of new equity offerings. These results are consistent with the Scholes and Wolfson (1989) hypothesis that managers in need of equity capital use DRPs to mitigate the adverse stock price effects of new equity issue announcements. Furthermore, there is a significant difference in the price response of discount and no discount DRPs for industrial firms. This result is supportive of the signaling potential of discount DRPs. Supportive evidence is also found in the analysis of firm characteristics for industrial firms.  相似文献

This paper compares the optimal lending decisions of financial intermediaries that differ in their risk exposure. All intermediaries are assumed to face a loan demand described by a random applicant arrival process with each applicant offering a unique risk-adjusted rate of return; loan demand is therefore uncertain in both quantity and quality. The intermediaries differ in terms of their risk exposure because of disparate funding practices. Intermediaries functioning as brokers minimize their exposure by borrowing funds only as demand is realized, whereas those behaving as asset-transformers borrow in advance of realizing loan demand, thereby maintaining a loanable funds inventory and sustaining the related exposure. The optimal sequential lending policy is shown to involve setting a credit standard that becomes stricter with the length of the intermediary's planning horizon and the volume of loans outstanding. Most importantly, it is shown that brokers adopt stricter credit standards than asset-transformers and therby reduce their volume of lending.  相似文献

This paper develops a set of diagnostic tests which can shed light on why a particular model is failing and indicate what steps might be taken to make the model consistent with asset returns. Theoretical bounds on the moments of a stochastic discount factor are derived as a function of the moments of observed asset returns. Particular attention is paid to restrictions on moments other than the variance. These bounds can also be used to measure the information about the distribution of the discount factor contained in the moments of various asset returns. As an application of this methodology, bounds on the discount factor are estimated using size-based portfolios, and the results are used to analyze the small firm effect. Empirical results indicate, for the period 1926–1975, that moments of the returns of small firms contain information about the discount factor that is not contained in the moments of the returns of large firms and/or a proxy of the aggregate wealth portfolio. However, this difference disappears when more recent data is included.  相似文献

The Bright Side of Internal Capital Markets   总被引:7,自引:0,他引:7  
We examine capital expenditure decisions of discount firms in response to Wal-Mart's entry into their markets. Before Wal-Mart's entry, focused incumbents and discount divisions of diversified incumbents are similar in size, geographic dispersion, and firm debt levels. However, discount divisions of diversified firms are significantly more productive. After Wal-Mart's entry, diversified firms are quicker to either "exit" the discount business or "stay and fight." Also, their capital expenditures are more sensitive to the productivity of their discount business. Internal capital markets function well, as transfers are away from the worsening discount divisions. It appears diversified firms make better investment decisions.  相似文献

The paper presents formulation of the debtor-creditor hypothesis of redistribution of wealth in inflation. A portfolio model is used to derive an expression for the change in real rate of return measuring inflation gain or loss. The situation is relevant when the market rates of return fail fully to respond to expectations or when the inflation rate is not fully predictable. Of the wealth transfers from the private sector to the government in inflation, the model only covers the case of inflation tax. The model is employed to consider the controversial issue of inventory gains in inflation. The conclusion is that neither LIFO or FIFO can be regarded as having general validity as inventory accounting method in inflation.  相似文献

Current Wealth,Housing Purchase,and Private Housing Loan Demand in Japan   总被引:3,自引:0,他引:3  
Japanese households accumulate wealth for down payments at a high rate. Therefore, current wealth plays an important role in home acquisition as well as public loans whose direct mortgage lending is a strong support for home purchasers. We estimate the wealth effect on private mortgage debt as well as housing consumption by applying a model where mortgage-debt demand is derived from house-purchase decisions and is determined jointly with housing consumption. We use a simultaneous equation Tobit estimation method. Wealth effects on private mortgage debt, likelihood of borrowing, and housing consumption are not elastic. On the other hand, a change in housing consumption affects the likelihood of borrowing elastically much more than the private mortgage amount of borrowers. Housing and private mortgage markets fluctuate very closely with the number of participants in the mortgage market. Therefore, the number of housing starts is linked strongly to the private mortgage market.  相似文献

The optimal capital growth strategy or Kelly strategy has many desirable properties such as maximizing the asymptotic long-run growth of capital. However, it has considerable short-run risk since the utility is logarithmic, with essentially zero Arrow–Pratt risk aversion. It is common to control risk with a Value-at-Risk (VaR) constraint defined on the end of horizon wealth. A more effective approach is to impose a VaR constraint at each time on the wealth path. In this paper, we provide a method to obtain the maximum growth while staying above an ex-ante discrete time wealth path with high probability, where shortfalls below the path are penalized with a convex function of the shortfall. The effect of the path VaR condition and shortfall penalties is a lower growth rate than the Kelly strategy, but the downside risk is under control. The asset price dynamics are defined by a model with Markov transitions between several market regimes and geometric Brownian motion for prices within a regime. The stochastic investment model is reformulated as a deterministic programme which allows the calculation of the optimal constrained growth wagers at discrete points in time.  相似文献

Advances in technology, as well as regulatory and legislative actions, have led to an increase in the quantity of information available to the public. This paper experimentally examines the effects of information quantity and consistency (or directional agreement) on the judgments and trading behavior of naïve investors, holding constant the quality (or predictive value) of information. In my experiment, investors receive accounting signals and make predictions and trading decisions for 24 separate firms. I find that increasing the quantity and consistency of information leads naïve investors to show greater judgment confidence and trading aggressiveness. Increased quantity reduces investors’ expected wealth in laboratory markets, while the effect of consistency on expected wealth depends on the relationship between the low- and high-quality signals investors receive. Results highlight possible unintended consequences of increased disclosure and suggest directions for future experimental and archival research.  相似文献

This paper develops a model that integrates inventory and labor decisions. We extend a model of inventory behavior to include a detailed specification of the role of labor input in the production process, distinguishing between employment, hours and effort per worker. We estimate jointly the Euler equations for inventories and employment, a labor compensation schedule, and an hours requirement function with the cross-equation restrictions imposed. The econometric results shed light on several important topics, including the shape of the marginal cost of output, the role of labor hoarding as an explanation of pro-cyclical productivity, and the persistence of inventory stocks.  相似文献

We examine the effect of discount rate changes on stock market returns, volatility, and trading volume using intraday data. Equity returns generally respond negatively and significantly to the unexpected announcements; however, the effect of expected changes on equity returns is insignificant. Furthermore, our results indicate that equity prices respond to announcements within the trading period/hour after the information release. An indication of a return reversal is too small to cover the full transaction costs. Unexpected discount rate changes also contribute to higher market volatility although the volatility is short-lived. Similarly, unexpected changes in discount rates induce larger trading volume while expected changes do not. Abnormal trading volume occurs only in period t. Our results also support the notion that unexpected changes in the discount rates impact market returns irrespective of the Federal Reserve operating procedures.  相似文献

The large, persistent fluctuations in international trade that cannot be explained in standard models by changes in expenditures and relative prices are often attributed to trade wedges. We show that these trade wedges can reflect the decisions of importers to change their inventory holdings. We find that a two-country model of international business cycles with an inventory management decision can generate trade flows and wedges consistent with the data. Moreover, matching trade flows alters the international transmission of business cycles. Specifically, real net exports become countercyclical and consumption is less correlated across countries than in standard models. We also show that ignoring inventories as a source of trade wedges substantially overstates the role of trade wedges in business cycle fluctuations.  相似文献

We find that diversified firms in New Zealand are associated with a value discount of 19–42 per cent relative to single‐segment (undiversified) firms. Although several competing explanations have been offered in the literature, we find that the strength of corporate governance explains between 15–21 per cent of this discount. Specifically, board size, busyness of directors, CEO ownership and whether or not compensation of directors includes equity‐based components collectively explain a large part of the reported discount. Our results from companies trading in New Zealand complement recent findings in the US by not only confirming the existence of a diversification discount but also emphasizing the role of poor governance in destroying shareholder wealth by pursuing a value‐destroying corporate strategy. All our results hold after controlling for potential endogeneity in the decision to diversify and the choice of corporate governance structure by employing two‐way fixed‐effects and dynamic‐panel generalized method of moments regression techniques.  相似文献

Although the insurance industry has a significant economic role, few theoretical studies link insurance with the overlapping generations economy. This study suggests a new overlapping generations model that includes insurance in the agents' economic decisions under the uncertainty of financial losses. In this insurance model, we derive risk-averse workers' optimal insurance purchases and consumption based on the insurance-adjusted valuations, which are the present value of the income streams minus insurance premiums paid in the future. The theoretical equilibrium model predicts capital returns, wealth, labor supply, etc. Our findings show that higher workforce and technological progress increase private insurance demand and reduce the capital-output ratio, and higher losses as a fraction of output increase social insurance demand and reduce the capital-output ratio via numerical comparative statics.  相似文献

This study uses the discrete-time option pricing model for the evaluation of the firm's inventory decision under demand uncertainty. The paper establishes the following optimal inventory decision implications: the optimal order quantity is positively related to the product selling price, product salvage value, interest rate, and the size of the outstanding orders; and negatively related to the product cost. The effect of demand uncertainty on the optimal order quantity is shown to be ambiguous. This study also shows that the maximum present value of profit from the contingent claims approach can be substantially different from that of the modified standard newsboy problem.  相似文献

The introduction of an endogenous labor decision represents a challenge for models that seek to jointly explain asset pricing and business cycle facts. This paper shows that several improvements can be made if a standard real business cycle model is augmented with a novel preference specification that increases the stochastic discount factor volatility and simultaneously reduces the wealth elasticity of labor supply.  相似文献
