The Effects of Occupational Injuries After Returns to Work: Work Absences and Losses of On-the-Job Productivity

We extend the research on postinjury employment by estimating productivity losses for workers with permanent partial disabilities (PPDs) in the first three years after injury. Our method distinguishes between productivity losses attributed to spells of work absence versus reduced earnings during spells of employment. The method is applied to data for 800 Ontario workers with PPDs. The results document large productivity losses persisting at least three years after injury, with different loss patterns for workers returning to stable versus unstable employment. Human capital investments or job accommodations can reduce productivity losses, but the significant determinants of losses differ for the stable versus unstable employment groups.     

Estimating the effectiveness of extension information systems using farm trials and subjective probabilities

A method of combining survey data and Dairy Herd Improvement Association (DHIA) records to achieve low cost farm trials is presented. Farm trials and surveys of current practices and production responses are useful to identify yield gaps between expectations predicted from experimental findings and actual field results. Different management schemes can be ranked using subjective probabilities and stochastic dominance to enhance successful implementation of research findings and to increase the feedback between researchers, extension workers, and producers. A survey of current masitis control practices and expected milk yield response is the example. Combining survey results with DHIA records allowed estimating the relationship between somatic cell counts (SCC) and milk yield. Eliciting beliefs about the relationship between SCC and milk yield showed that producers agreed with predictions from the statistical model. Subjective probabilities about SCC and mastitis control practices showed that our sample of experts and producers consistently ranked the different practices but extension agents had no consensus about the the most or least effective ones.     

Organisation vs. culture: Japanese automotive transplants in the US

It has long been argued that the Japanese production organization is culture-bound and therefore not transferable to other countries. This article examines seven major Japanese automobile assembly plants and over 270 Japanese automotive parts suppliers in the US. The successful transfer of Japanese work and production organization in these ‘transplants’ suggests that Japanese production practices are organizational forms which can be uncoupled from Japanese culture and transferred to other countries.     

Towards a complete real-time electricity market design

The general design for the real-time electricity market presented in this paper optimizes and prices both real and reactive power simultaneously in an AC setting, where all assets—generation, load and transmission—are allowed to bid and are financially settled at the locational price times energy consumed or produced. The result is that transmission lines are compensated for both capacity and admittance, providing incentives for efficient operation of transmission-related assets such as FACTS devices, if price-taking behavior is assumed. Losses are incorporated into the design and become an operating cost for transmission. The market design is shown to be revenue neutral and, under some assumptions, nonconfiscatory.      

Information–driven trading at the Prague Stock Exchange: Evidence from Intra–Day Data

Many observers argue that informed and insider trading is widespread in the emerging financial markets of transition countries, yet rigorous treatment of this issue has been virtually non–existent. The current paper estimates the extent of informed trading on the Prague Stock Exchange (PSE) using intra–day transaction data. Our estimates confirm that the average share of informed trading is equal to 0.32, which is high relative to developed markets and varies considerably among stocks. Using the Easley et al. (1996) approach on the very best segment of the PSE we obtained a high average probability of informed trading. Since data used in this study cover the period after the major attempts to improve market regulations, our results indicate that the PSE needs further strengthening to recover credibility and to become a real source of corporate financing. JEL classification: G14, G15.     

Are recent segment disclosures of Japanese firms useful?: Views of Japanese financial analysts

Since 1990, the Japanese Ministry of Finance (MOF) has required Japanese firms to disclose segment data in annual financial statements. Using a survey instrument, we examine whether Japanese analysts find these segment disclosures to be useful. Our study finds that analysts perceive that segment data aid them in forecasting consolidated sales and net income. However, results also show that analysts are concerned that Japanese firms do not define segments meaningfully and consistently and are arbitrary in the allocation of common costs. Further, the analysts do not believe that the usefulness of segment data improves when it is audited. These results have implications for investors in Japanese stocks and accounting policy bodies, such as the US Securities and Exchange Commission (SEC).     

Trade Creation,Replacement, and Destruction in Regional Trade Agreements: Micro‐level Evidence for the UK*

Empirical questions surrounding the effect of regional trade agreements on international trade have typically been answered with reference to macro‐level gravity equations. Prominent within this has been whether they create or divert trade. In this paper, motivated by the recent development of theories of export‐platform FDI, we use micro‐level data to explore the part of trade diversion that follows from FDI. Using information on acquisition FDI in the UK manufacturing sector between 1988 and 1998 we find evidence of trade creation, replacement, and destruction from FDI external and internal to the EU.     

Moral Hazard,portfolio allocation,and asset returns for thrift institutions

This article examines the earnings performance of nontraditional assets allowed to thrifts since the early 1980s. It uses the statistical cost accounting methodology developed by Hester and Zoellner to estimate average returns on thrift portfolio investments for the years ending June 30, 1987 and June 30, 1988. Results show that average returns on land loans, service corporation investment, real estate investment, and commercial loans were significantly lower than returns on more traditional assets. The results are far more pronounced at capital deficient institutions, lending support to the hypothesis that they used nontraditional investments as a means of exploiting the deposit insurance system. Returns on nontraditional assets are significantly affected by geographic factors, even for well capitalized institutions. The article concludes with an evaluation of the reimposition of portfolio restrictions on thrifts by the Financial Institutions Reform, Recovery, and Enforcement Act of 1989.The views expressed in this paper are those of the authors and do not necessarily represent the views or opinions of the Federal Housing Finance Board, the Board of Governors of the Federal Reserve System, or the Federal Deposit Insurance Corporation.

HOUSEHOLD AND ENTERPRISE SAVING AND CAPITAL FORMATION IN THE UNITED STATES: A MARKET TRANSACTIONS VIEW

Contrary to conventional macro theory, it is not the consumption function in terms of either the permanent income or the life-cycle theory of saving that has furnished the saving for enterprise capital formation in the United States. Household sector accounts indicate that household gross saving, correctly measured, did not exceed household gross capital formation in the United States over the period since 1947. Furthermore, historical data on enterprise saving and capital formation in the United States, and cross-section tax return data of U.S. corporations indicate that the gross saving for many enterprise sectors has been equal to or greater than their gross capital formation. There are exceptions, however: these same sources indicate that public utilities have borrowed substantially to finance their capital formation. Finally, it is argued that employer pension and insurance reserves held by financial institutions for future benefit payments represent retained income of a nature similar to undistributed profits, and that these constitute a source of saving in the economy.
