Assessing market power in the U.S. commercial banking industry under deregulation

This study attempts to investigate market power in the U.S. commercial banking industry since the U.S. government began to deregulate the banking sector in the early 1990s using the static Bresnahan–Lau model (SBLM) and dynamic Bresnahan–Lau model with error corrections (DBLEC). In particular, panel unit root and panel cointegration techniques are utilized to examine the dynamic model. The empirical results of the SBLM show that the banking industry is highly competitive. The empirical results of DBLEC also suggest that the commercial banking industry is close to being perfectly competitive in the short run. By contrast, the adjustment speeds of the supply and demand sides towards the long-run equilibrium are quite slow in that market, which implies that the U.S. commercial banks enjoy a certain degree of long-run market power.     

Divestiture policy and operating efficiency in U.S. electric power distribution

Divestiture of generation assets by vertically integrated electric utilities has been a key element of restructuring in the U.S. The resulting generation sector has received much attention, but the standalone distribution sector that has been simultaneously created has received very little. This paper addresses the effects of divestiture policy on the operating efficiency of the resulting distribution utilities. Using data envelopment analysis to measure operating efficiency, we examine 73 utilities in the period 1994–2003 and find that the major divestitures that were required by state regulators had large adverse effects on efficiency, whereas utilities that divested at their own initiative had at worst neutral efficiency outcomes. These results raise serious questions about one of the centerpieces of electricity restructuring.     

Sunspots and self-fulfilling beliefs in the U.S. housing market

This paper provides a rational expectations equilibrium framework to organize the following observations about the U.S. housing market from 1975 to 2007: (i) housing occupancy patterns were approximately constant, (ii) rents were stable, and (iii) house prices appreciated considerably in the late 1990s. I develop a model based on search and matching theory and close it by specifying a state of household confidence that is assumed to take one of two sunspot-driven values: normal or exuberant. The model generates a substantial increase in house prices and stable rents as the probability of the exuberant state increases, driven by self-fulfilling beliefs. I explore which aspects of the parameterization are important for generating a large appreciation in house prices in the model.

Competition and price asymmetries in the Greek oil sector: an empirical analysis on gasoline market

This article attempts to investigate the issue of asymmetries in the transmission of shocks to input prices and exchange rate onto the wholesale and retail price of gasoline respectively. For this purpose, we utilise the error-correction methodology in the Greek gasoline market. The sample consists of monthly data covering the period of January 1988 to June 2006. We also try to analyse by using impulse response functions the effect of competition on the dynamic adjustment of gasoline price to which has been paid scant attention in the past. The results favour the common perception that retail gasoline prices respond asymmetrically to cost increases and decreases both in the long and the short-run. At the wholesale segment, there is a symmetric response of the spot prices of gasoline towards the adjustment to the short-run responses of the exchange rate. Lastly, after the deregulation, wholesale prices of gasoline tend to gradually restore equilibrium triggered by a price shock compared to the regulated period.     

Exchange rate pass-through in the U.S. market: A cross-country and cross-product investigation

Foreign exporters in general and Japanese exporters in particular have been observed to price to market in the U.S. Are there significant differences in the pricing behavior among exporters from different countries? Is the Japanese export pricing behavior unique? This paper addresses these questions and finds that while there is obvious variation in exchange rate pass-through among products, which relates significantly to the degree of product differentiation, no single exporter to the United States is unique in their pricing behavior.     

Technological change under residual risk regulation: The case of coke ovens in the U.S. steel industry

An engineering-economic model is used within a dynamic setting to determine the least cost mix of investment and import activities as the U.S. steel industry faces successively tighter controls on coke oven emissions over the next 10 years. In response to Maximum Achievable Control Technology (MACT) standards proposed for 1995, U.S. steel producers would likely export their toxic pollution by importing 6 million tons of coke per year. About 4 million tons of coke oven capacity is retrofit and about 1 million tons of annual coke consumption is replaced by new iron technologies, such as Corex. The Lowest Achievable Emission Rate (LAER) standards proposed for 1998 roughly double the coke oven retirements estimated to occur under MACT. Coke imports also are substantial but are no higher than under MACT because the additional time allows the industry to invest in more coke-saving blast furnaces and in new less toxic coke-making technologies, such as the Jewell process. The LAER standards in conjunction with higher capital costs, however, force coke imports to more than 8 million tons per year and sharply increase imports of semi-finished steel. Such a situation could exacerbate existing disputes on international steel trade.The authors are associate professor, instructor, and graduate student, respectively.

Derivatives holdings and market values of U.S. bank holding companies

We examine the impact of derivatives held by US bank holding companies on their market valuations over the period 2000 to 2010. By using bank-level data with detailed information on the notional amounts of derivative positions according to holding purposes and underlying asset types, our regression analyses provide three main findings. First, derivative instruments held for hedging rather than trading purposes contribute to enhancing market values. Second, the positive effects exhibit nonmonotonic patterns indicating that excessive amounts of derivatives holdings deteriorate market values. Third, interest rate derivatives are the main source of high valuations.     

Aggregate price responses to wage and productivity changes: Evidence from the U.S.

This papei examines the dynamic responses of prices to wage and productivity changes and distinguishes between short-run and long-run effects. The long-run solution of the dynamic specification is consistent with the hypothesis of markup pricing over unit labour costs. The restrictions implied by this long-run behaviour are not rejected.by U.S. data. In addition, the evidence supports the view that the short-run wage effects are significantly stronger than productivity effects.     

Trade-mediated biotechnology transfer and its effective absorption: an application to the U.S. forestry sector

In this paper, we analyze the consequences of biotechnology innovations in the United States forest sector (logging) by modeling technology transfer embodied in trade flows and its absorption. A seven-region, seven-traded-commodity version of a dynamic computable general equilibrium model is used to achieve this task. A 0.63% Hicks-neutral biotechnological progress in the source region (U.S.) has differential impacts on the productivity of the log-using sectors in the domestic as well as in the recipient regions. Since recipient regions' ability to utilize biotechnology innovations depends on their absorptive capacity (AC) and structural similarity (SS), we construct the AC and SS indices based on multiplicity of factors such as human capital endowments, skill content and social appropriateness of the new innovations. The model results show that biotechnological innovations in the U.S. forest sector result in a significant increase in timber production. Following the productivity improvements and its embodied spillover, wood products and pulp and paper sectors in the U.S. register higher productivity growth. The role of AC and SS in capturing technical change is shown to be evident. In the face of growing regulations on timber production from public forests, increasing productivity through biotechnology may be the most effective way to meet the consumer demand for forest products.     

Effects of technical innovation on market value of the U.S. semiconductor industry

This article discusses the effects of technical innovation on the market value (MV) of the American semiconductor industry from the perspective of investors in the securities market. The study quantifies the technical innovations of the semiconductor industry and uses the proportional change of Average Process Technology (APT) as a proxy variable to measure the industrial capability of technical innovations and to act as one of the explanatory variables of a regression model for discussing the connection between technical innovation and MV. The results indicate that: 1) the degree of technical innovation and the proportional change in productivity of the semiconductor industry are the major factors that affect proportional change in the MV of the U.S. semiconductor industry; 2) regardless of the size of a company's MV or the companies' classification in terms of products and services (the Equipment & Material Sector, the Board Line Sector, the IC & Chip Sector and the Fabless & Specialist Sector), the degree of technical innovation shows a significant positive effect on MV.     

A gender analysis of U.S. labor market policies for the working poor

Current anti-poverty policy proposals focus on welfare reform to the exclusion of reforming the low-wage labor market. In contrast, we compare two policy proposals aimed at low-wage labor markets: a national comparable worth policy and an increase in the minimum wage. With both policies we pay specific attention to their impact by gender. Our findings suggest that while both would reduce poverty among working women, the impact of a comparable worth policy on female poverty would be greater under most scenarios presented. It is estimated that an increase of 96 cents per hour in the national minimum wage would be necessary to equal the poverty reduction effect for women workers of a comparable worth policy which excludes small employers. Both policies decrease the incidence of povertylevel wages less among men, since roughly 60 percent of minimum wage workers are women. Additionally, not only would a national comparable worth policy improve the economic status of low-waged women workers, it would also narrow the gap between male and female poverty. While an increase in the minimum wage would also reduce this gap, comparable worth would virtually eliminate it.     

Cointegration relationships and hedonic pricing of differentiated commodities: an application to price dynamics in the US dairy sector

This study investigates the implications of hedonic pricing for price dynamics of differentiated commodities. A conceptual model of hedonic pricing is developed under a Leontief technology, showing how commodity prices reflect the underlying value of their components. Implications for the existence of cointegration relationships among commodity prices are derived. An application to the pricing and dynamics of selected US dairy commodities is presented. It provides evidence on the role of component valuation in the dynamics of dairy commodity prices in the short run as well as in the long run. Distinguishing between market regime and government regime (when the government price support is active), the analysis finds significant differences in dairy price dynamics between the two regimes.     

Emerging market sovereign spreads,global financial conditions and U.S. macroeconomic news

We investigate the impact of global financial conditions, U.S. macroeconomic news and domestic fundamentals on the evolution of EMBI spreads for a panel of 18 emerging market (EM) countries using daily data. To this end, we consider not only the conventional panel cointegration procedures but also the recent common correlated effects method to tackle cross-section dependence that may stem from common global shocks such as contagion. The results suggest that the long-run evolution of EMBI spreads depends on global financial conditions, crises contagion and domestic fundamentals proxied by sovereign ratings. The results from panel equilibrium correction models suggest that EMBI spreads respond substantially also to U.S. macroeconomic news and changes in the Federal Reserve's target interest rates. The magnitude and the sign of the effect of the U.S. news, however, crucially depend on the state of the U.S. economy, such as the presence of inflation dominance.     

Efficiency and market share in the Hungarian corporate sector

This paper investigates the link between competition and efficiency for the Hungarian corporate sector during various phases of the transition process. We employ frontier production functions to explore differences among groups of firms, and to identify the typical adjustment process of each group separately throughout the transition period until 1997. The estimated production functions indicate a gradual improvement in efficiency and a shift from decreasing to increasing returns to scale due to the growing share of small firms. Market share can be explained by domestic and foreign competition and by the efficiency of the firm. JEL classification: C23, D21, D24.
