In the field of economics, perhaps the most important break with the past - one that leaves open huge areas for future work - lies in the economics of information. It is now recognized that information is imperfect, obtaining information can be costly, there are important asymmetries of information, and the extent of information asymmetries is affected by actions of firms and individuals.
In this article, the authors focus on impacts of tax rates and, in particular, tax progressivity on the decision to become an 'entrepreneur.' While a proportional tax with a full loss offset will not affect the entry decision for a risk-neutral individual, a progressive schedule with imperfect loss offsets can discourage entry. The authors find substantial evidence for this effect on entrepreneurship using variation in tax schedules faced by households in the Panel Study on Income Dynamics (PSID) over the period from 1979 to 1992.
Previous theories of financial market rationing focussed on a single market, either the credit or the equity market. An interesting question is whether credit and equity rationing are mutually compatible, and how they interact. We consider a model with two-dimensional asymmetric information, where entrepreneurs have private information about both the expected returns and the risk of their projects. We show that credit and equity rationing may occur individually or simultaneously.
In a dynamic model of moral hazard, competition can undermine prudent bank behavior. While capital-requirement regulation can induce prudent behavior, the policy yields Pareto-inefficient outcomes. Capital requirements reduce gambling incentives by putting bank equity at risk. However, they also have a perverse effect of harming banks' franchise values, thus encouraging gambling. Pareto-efficient outcomes can be achieved by adding deposit-rate controls as a regulatory instrument, since they facilitate prudent investment by increasing franchise values.
This paper reviews briefly the arguments for capital market liberalization, and identifies their theoretical and empirical weaknesses. This provides the foundations for the argument for intervention in short-term capital flows. The paper concludes with a brief discussion of the various ways in which such interventions may be implemented.
The author argues that the Washington consensus is too narrow in its objectives - in its focus on GDP - and in what it sees as the instruments of development, the improvement of resource allocation, through trade liberalization, privatization and stabilization, that development needs to be seen as a transformation of society, a change in mindsets, and that workers and workers' institutions have to be at the center of the development process.
This century has been marked by two great economic experiments. The outcome of the first set, the socialist experiment that began, in its more extreme form, in the Soviet Union in 1917, is now clear. The second experiment is the movement back from a socialist economy to a market economy. Ten years after the beginning of the transition in Eastern Europe and the Former Soviet Union: How do we assess what has happened? What are the lessons to be learned?
One possible explanation for bidding firms earning positive abnormal returns in diversifying acquisitions in the 1960s is that internal capital markets were expected to overcome the information deficiencies of the less-developed capital markets. Examining 392 bidder firms during the 1960s, we find the highest bidder returns when financially "unconstrained" buyers acquire "constrained" targets. This result holds while controlling for merger terms and for different proxies used to classify firms facing costly external financing.
Previous research has shown that wages in industries characterized by higher rates of technological change are higher. In addition, there is evidence that skill-biased technological change is responsible for the dramatic increase in the earnings of more educated workers relative to less educated workers that took place during the 1980s.

The author argues that trade liberalization must be balanced in agenda, process and outcomes, including not only sectors in which developed countries have a comparative advantage, like financial services, but also those in which developing countries have a special interest, like agriculture and construction services. Account must be taken of the marked disadvantage that developing countries have in participating meaningfully in negotiations.
Both managerial ownership and performance are endogenously determined by exogenous (and only partly observed) changes in the firm's contracting environment. We extend the cross-sectional results of Demsetz and Lehn (1985), (Journal of Political Economy, 93, 1155?1177) and use panel data to show that managerial ownership is explained by key variables in the contracting environment in ways consistent with the predictions of principal-agent models. A large fraction of the cross-sectional variation in managerial ownership is explained by unobserved firm heterogeneity.
Recent research on business investment decisions suggests that real investment in plant and equipment is quite sensitive to changes in the user cost of capital, pointing to the possibility that long-run changes in tax policy may have a significant impact on an economy's capital stock. Indeed, many countries have at times adopted investment tax incentives to stimulate investment. The prevalence of investment incentives suggests that local policy-makers believe these are effective in increasing investment at a reasonable cost in terms of lost revenue.
Examines the correlation between investments and proxies for changes in net worth or internal funds and the importance of this correlation for firms likely to face information related capital-market imperfections. Developments and challenges in empirical research; Analytical underpinnings of models of capital market imperfections; Model's application to investment activities.
The effects of tax reform on corporate financial decisions help determine whether reform will increase capital formation and simplify the tax system. This paper describes the effects of fundamental tax reform on corporate tax planning and summarizes economists' knowledge of the magnitude of these effects. We analyze both income tax reform, consisting of integrating the corporate and personal income taxes, and moving to a broad-based consumption tax. As prototypes of reform, we use the U.S.
Since technological change influences the rate at which human capital obsolesces and also increases the uncertainty associated with human capital investments, training may increase or decrease at higher rates of technological change. Using the National Longitudinal Survey of Youth, we find that production workers in manufacturing industries with higher rates of technological change are more likely to receive formal company training.

It is argued that, with respect to efficiency gains, the distinction between reform toward a broad-based income tax and reform toward a broad-based consumption tax is relatively minor. This is not to say that there are not important efficiency and distributional consequences of moving from the current tax system to a broad-based consumption tax. Most such consequences can be traced to reform of the income tax.
As a tax base, 'consumption' is sometimes argued to be less fair than 'income' because the benefits of not taxing capital income accrue to high-income households. We argue that, despite the common perception that consumption taxation eliminates all taxes on capital income, consumption and income taxes actually treat similarly much of what is commonly called capital income. Indeed, relative to an income tax, a consumption tax exempts only the tax on the opportunity cost of capital. In contrast to a pure income tax, a consumption tax replaces capital depreciation with capital expensing.
We use firm-level panel data to explore the extent to which fixed investment responds to tax reforms in 14 OECD countries. Previous studies have often found that investment does not respond to changes in the marginal cost of investment. We identify some of the factors responsible for this finding, and employ an estimation procedure that sidesteps the most important of them. In so doing, we find evidence of statistically and economically significant investment responses to tax changes in 12 of the 14 countries.
This article suggests that the introduction of bank branching restrictions and federal deposit insurance in the United States likely was motivated by political considerations. Specifically, we argue that these restrictions were instituted for the benefit of the small unit banks that were unable to compete effectively with large, multiunit banks. We analyze this "political hypothesis" in two steps.
Case studies of a number of specific drugs have shown that these drugs reduced the demand for hospital care and, in some cases, led to decreases in mortality. For example, according to the Boston Consulting Group Inc., operations for peptic ulcers decreased from 97,000 in 1977, when H2 antagonists were introduced, to 19,000 in 1987; this is estimated to have saved $224 million in annual medical costs. The recent Scandinavian Simvastatin Survival Study indicated that giving the drug simvastatin to heart patients reduced their hospital admissions by a third during five years of treatment.
The U.S. Social Security system is in need of reform. Its trustees forecast that, absent changes, contributions will fall below benefits in 2012, and the system's trust fund will be exhausted in 2030. Many have discussed achieving system solvency by raising taxes and cutting benefits, but recently a more fundamental reform has been proposed, namely, privatization of some or all aspects of Social Security. This article identifies key economic issues that must be addressed in the debate over a privatized system in the U.S.
Examines the effectiveness of incentives to promote household saving in the United States. Individual retirement accounts; 401(k) plans; Cost-benefit approach to saving incentives; Welfare-theoretic approach to saving incentives.
Theoretical work on financing costs under asymmetric information has linked shifts in firms' internal funds and investment spending, holding constant investment opportunities. An impediment to convincing tests of these models is the lack of firm-level data on the relative cost of internal and external funds. We use a tax experiment, the surtax on undistributed profits in the 1930s, to identify firms' relative cost of internal and external funds by calculating surtax margins.
This paper examines CEO pay in the banking industry and the effect of deregulating the market for corporate control. Using panel data on 147 banks over the 1980s, we find higher levels of pay in competitive corporate control markets, i.e., those in which interstate banking is permitted. We also find a stronger pay-performance relation in deregulated interstate banking markets. Finally, CEO turnover increases substantially after deregulation.
The article presents a study using the Euler equation for capital accumulation by individual business firms. First, authors' use an estimation strategy based on the Euler equation representation of firms' investment decisions. This strategy reflects reservations with standard investment models based on the q theory with adjustment costs. In particular, there are well-known problems in measuring marginal q, as well as concerns that observed stock market valuations may not accord with the predictions of the efficient markets hypothesis.
Micro data studies of household saving often find a significant group in the population with virtually no wealth, raising concerns about heterogeneity in motives for saving. In particular, this heterogeneity has been interpreted as evidence against the life cycle model of saving. This paper argues that a life cycle model can replicate observed patterns in household wealth accumulation after accounting explicitly for precautionary saving and asset-based, means-tested social insurance.

A unique dataset collected from the personnel records of a large company is used to study the relationship between on-the-job training and worker productivity. The analysis shows how information contained in a company database is useful for eliminating heterogeneity bias in the estimation of training's impact on wages and job performance.
This paper examines predictions of a life-cycle simulation model—in which individuals face uncertainty regarding their length of life, earnings, and out-of-pocket medical expenditures, and imperfect insurance and lending markets—for individual and aggregate wealth accumulation. Relative to life-cycle or buffer-stock alternatives, our augmented life-cycle model better matches a variety of features of U.S.

In this paper, the author outlines what he believes to be causes of why many people do not save. Much of the research examining levels of consumption, saving, and wealth, as well as their responsiveness to policy, has been done using a life-cycle model with the simplifying assumption of perfect certainty. More recently, a line of inquiry has examined the effects of uncertainty on saving, generally in the context of highly stylized models. This research has shown that, in these models, uninsured earnings uncertainty can alter optimal saving behavior in a variety of important ways.

The article focuses on investment behavior using tax reforms as natural experiments. Economists and policymakers have long been interested in measuring the effects of changes in the returns to and costs of business fixed investment. That interest reflects both theoretical and practical concerns which have stimulated a large body of empirical research using aggregate and micro-level data. This literature has reached few unambiguous conclusions.
