How to Sell the Tubes — and Why

John Hibbs described in the last JEA the dangers awaiting London's transport system if it were exposed to further political manipulation. From his analysis of the transport difficulties besetting New York, James Ramsey outlines the measures by which Tom King. Transport Secretary, can use privatisation to help whatever transport administration survives the dismemberment of the GLC.     

Business Cycle Implications of Internal Consumption Habit for New Keynesian Models

We study the implications of internal consumption habit for New Keynesian dynamic stochastic general equilibrium (NKDSGE) models. Bayesian Monte Carlo methods are employed to evaluate NKDSGE model fit. Simulation experiments show that internal consumption habit often improves the ability of NKDSGE models to match the spectra of output and consumption growth. Nonetheless, the fit of NKDSGE models with internal consumption habit is susceptible to the sources of nominal rigidity, to spectra identified by permanent productivity shocks, to the choice of monetary policy rule, and to the frequencies used for evaluation. These vulnerabilities indicate that the specification of NKDSGE models is fragile.     

Law,Stock Markets,and Innovation

We study a broad sample of firms across 32 countries and find that strong shareholder protections and better access to stock market financing lead to substantially higher long‐run rates of R&D investment, particularly in small firms, but are unimportant for fixed capital investment. Credit market development has a modest impact on fixed investment but no impact on R&D. These findings connect law and stock markets with innovative activities key to economic growth, and show that legal rules and financial developments affecting the availability of external equity financing are particularly important for risky, intangible investments not easily financed with debt.     

Mixed Integer Programming Revealed Preference Tests of Utility Maximization and Weak Separability of Consumption,Leisure, and Money

Swofford and Whitney (1987, 1988, 1994) investigated the validity of two key assumptions underlying representative agent models of macroeconomics. These assumptions are utility maximization and weak separability. Using mixed integer programming, we check revealed preference conditions for these assumptions. We find that M1, money defined by Friedman and Schwartz (1963), and a broad aggregate are weakly separable. We find that consumption goods and leisure and nondurables and services are weakly separable. We find that M2, M3, and MZM are not weakly separable. Finally, we find three categories of consumption, durables, nondurables and services, do not form an aggregate.     

Inventory Shocks and the Great Moderation

Why did the volatility of U.S. real GDP decline by more than the volatility of final sales with the Great Moderation in the mid‐1980s? One explanation is that firms shifted their inventory behavior toward a greater emphasis on production smoothing. We investigate the role of inventories in the Great Moderation by estimating an unobserved components model that identifies inventory and sales shocks and their propagation in the aggregate data. Our estimates provide no support for increased production smoothing. Instead, smaller transitory inventory shocks are responsible for the excess volatility reduction in output compared to sales. These shocks behave like informational errors related to production that must be set in advance and their reduction also helps explain the changed forecasting role of inventories since the mid‐1980s. Our findings provide an optimistic prognosis for a continuation of the Great Moderation, despite the dramatic movements in output during the recent economic crisis.     

Non‐legal‐tender paper money: the structure and performance of Maryland's bills of credit, 1767–75

In this article, Maryland's non‐legal‐tender paper money emissions between 1765 and 1775 are reconstructed to determine quantities outstanding and redemption dates, providing a substantial correction to the literature. Over 80 per cent of this paper money's current market value was expected real asset present value and under 20 per cent was liquidity premium. It was primarily a real barter asset and not a fiat currency. The liquidity premium was positively related to the amount of paper money per capita in circulation. This paper money traded below face value due to time‐discounting, rather than depreciation. Past scholars have simply confused depreciation with time‐discounting.     

POLITICAL AND JUDICIAL CHECKS ON CORRUPTION: EVIDENCE FROM AMERICAN STATE GOVERNMENTS

This paper investigates the effects of checks and balances on corruption. Within a presidential system, effective separation of powers is achieved under a divided government, with the executive and legislative branches being controlled by different political parties. When government is unified, no effective separation exists even within a presidential system, but, we argue, can be partially restored by having an accountable judiciary. Our empirical findings show that a divided government and elected, rather than appointed, state supreme court judges are associated with lower corruption and, furthermore, that the effect of an accountable judiciary is stronger under a unified government, where the government cannot control itself.     

COMPARATIVE ADVANTAGE IN JAPAN,KOREA, AND TAIWAN BETWEEN 1980 AND 1999: TESTING FOR CONVERGENCE AND IMPLICATIONS FOR CLOSER ECONOMIC RELATIONS

This paper seeks to explore the basis for a free trade agreement (FTA) between Japan and the Republic of Korea by comparing export patterns of these two countries with that of a nonmember—Taiwan—that is geographically close and is also a major exporter of machinery. After calculating indices of revealed comparative advantage (RCA) for 3‐digit SITC categories, we test for convergence of export patterns between each pairing of partners (Japan‐Korea, Korea‐Taiwan, and Japan‐Taiwan). We find that even though each partner has a statistically significant correlation of RCA indices, export patterns of Korea and Taiwan are converging with that of Japan, while in the case of Taiwan and Korea there is no significant convergence between their export patterns. Finally, we identify sectors where trade diversion is likely to occur and provide an upper‐bound estimate of the potential amount of trade that might be diverted from Taiwan by a Japan‐Korea FTA.     

BOARD STRUCTURE,ANTITAKEOVER PROVISIONS,AND STOCKHOLDER WEALTH

This paper’s regression analyses from a sample of 261 firms that adopted 486 antitakeover provisions (supermajority, classified boards, fair-price, reduction in cumulative voting, anti-greenmail and poison pills) in the 1984–88 period indicate that the negative market reactions to antitakeover provisions vary depending on firms’ board structures. This paper’s empirical evidence indicates that while separating the positions of CEO and chairperson of the board reduces the negative effect, increased outsider representation increases negative market reactions. © 1997 by John Wiley & Sons, Ltd.
