Factors That Account for the Large Variations in U.S. Export Prices

Using product level U.S. export data from 1989 to 2001, there is evidence that U.S. exporters price discriminate across markets. Variation in the quality of the products is one reason for the observed price differentiation. U.S. exporters also price discriminate based on transaction costs. Finally, U.S. exporters practice pricing-to-market and this pricing strategy is another source of the variations in U.S. export prices. Some of these conclusions though are weakened when export prices toward the center of the price distribution are considered. JEL no. F14     

Population age structure and the size of social security

"This paper uses a general overlapping generations model to analyze social security. Rather than focusing on intertemporal price and income considerations, however, the paper focuses on the effect of contemporaneous (same period) prices and income. The analysis shows that the old-age dependency ratio acts as a shadow price for old-age benefits. With this new shadow price, the equilibrium price and quantity of social security benefits and the level of the payroll tax rate are determined in a demand-supply framework with individual utility maximization. Three explicit demand functions (intergenerational contracts) are analyzed. The model is tested using [U.S.] time series data for the social security Old-Age and Survivors (OASI) program."     

The Impact of Passenger Mix on Reported “Hub Premiums” in the U.S. Airline Industry

This paper analyzes U.S. airline price and passenger data disaggregated at the fare class level for the year 2000. We find that although average prices to and from most airlines' hubs tend to be higher than those throughout the remainder of their systems, much of the difference can be explained by passenger mix (i.e., the proportion of leisure versus business passengers). Our results suggest, therefore, that many of the reported “hub premiums” in the previous literature may be overstated.     

The Impact of Farmland Transfers on Agricultural Investment in China: A Perspective of Transaction Cost Economics

There is growing concern that farmland transfers lead to less agricultural investment, which may adversely affect agricultural productivity growth in China. Prior research has primarily focused on the differences between owned cultivated land and rented plots, but little is known about how farmland transfers between relatives, which are popular in rural China, specifically affect agricultural investment. In this paper, we present a conceptual framework of transaction cost economics to compare different contracting strategies in China's farmland rental markets. As farmland rental markets in China are immature, land transfer between relatives establishes bilateral governance, which has the advantage of addressing the opportunistic activities of both parties and can ultimately increase investment by tenants. Based on data from two waves of household surveys, we empirically examine the impact of bilateral governance on the application of organic fertilizer, an indicator for agricultural investment. Our findings show that apart from economic factors, kinship is important to the functioning of farmland rental markets in rural areas.     

A Multiperiod Model and Experimental Evidence of Independence and “Lowballing”*

Abstract. Auditors, regulators, and academics are interested in the pricing practice of “lowballing” and its relationship to auditor independence. Several analytical models have examined these issues. However, these theories have gone untested primarily due to a lack of field data concerning important environmental variables. In this study, a multiperiod model of lowballing and independence is developed and tested in laboratory markets via the experimental economics methodology. The study contributes to the literature in two respects. First, it represents one of the first studies providing empirical evidence and theory testing of the relationship between lowballing and independence. Second, the model presents a new rationale for low-ball pricing and its relationship to auditor independence. Lowballing and impairment of independence, occurring without exogenous transaction costs, are caused by positing cross-sectional variation in audit cost and quality and an informational advantage that accrues to an incumbent auditor-client pair regarding future variation in these audit dimensions. The model is operationalized in a multiperiod laboratory market consisting of multiple sellers and buyers. Sixteen markets are conducted to test price and reporting predictions of the model. The markets strongly exhibit lowballing behavior, but the exact price predictions are generally not supported. The markets also support reporting predictions, with sellers deviating from truthful reporting (impairing their independence) only when additional future profits are greater than the additional cost of misreporting.

Information‐Processing Costs and Breadth of Ownership

Using the U.S. Securities and Exchange Commission's mandate of eXtensible Business Reporting Language (XBRL) as a natural experiment, this study investigates whether and how the decreased information‐processing costs brought about by XBRL influence firms’ breadth of share ownership. We find that the XBRL mandate is associated with an increase in the total number of a firm's shareholders. This finding is consistent with the notion that XBRL facilitates a more transparent environment and decreases information‐processing costs, thereby attracting more shareholders in general. More interestingly, we find that while XBRL adoption is associated with an increase in share ownership of individual and non‐U.S. foreign institutional investors, it is associated with a decrease in share ownership of U.S. domestic institutional investors. Further evidence shows that this asymmetric shift in share ownership is more pronounced for more complex firms. Our findings, taken together, suggest that the decreased information‐processing costs brought about by XBRL help firms establish a level playing field by reducing the information disadvantages of individual and foreign institutional investors over domestic institutional investors. Our results are robust to potential endogeneity concerns and alternative research designs.     

Are Investors Misled by “Pro Forma” Earnings?*

This paper uses stock market data to investigate the popular claim that investors are misled by the “pro forma” earnings numbers conspicuously featured in the press releases of some U.S. firms. We first document the frequency and magnitude of pro forma earnings in press releases issued during June through August 2000, and describe the 433 firms that engaged in this financial disclosure strategy. Our test period predates public expressions of concern by trade associations and regulators that pro forma earnings may mislead investors and the subsequent issuance of guidelines and rules on the disclosure of pro forma earnings numbers. We use two complementary approaches to determine whether the share prices that investors assign to pro forma firms are systematically higher than the prices assigned to other firms. Our market‐multiples tests for differences in price levels find some evidence suggesting that pro forma firms may be priced higher than firms that do not use the disclosure strategy. This apparent overpricing is not, however, related to the pro forma earnings numbers themselves. Our narrow‐window stock returns tests reveal no evidence of a stock return premium for pro forma firms at the quarterly earnings announcement date. Collectively, the results cast doubt on the notion that investors are, on average, misled by pro forma earnings disclosures despite the widespread concern expressed in the financial press and by regulators.     

Understanding the Cyclical Nature of Financial Intermediation Costs

Intermediation costs (i.e., all noninterest bank expenses) are counter‐cyclical and their changes have significant effects at the country‐level; however, the literature is silent on what drives their cyclicality. Previous studies have examined costs using cross‐sectional or low frequency data and thus cannot capture dynamic macroeconomic effects across time. We fill this gap by examining U.S. intermediation costs using a quarterly, bank‐level dataset from 1993 through 2012. This data set allows for the separation of microeconomic and macroeconomic factors affecting the cyclicality of costs. The analysis shows that house prices are the main driving source of this counter‐cyclicality. Because housing is used as collateral, a price decline leads banks to increase their operating costs for monitoring, screening and litigation costs which cause a credit crunch in the economy.     

An empirical analysis of the unit labor cost-product price relation in the U.S. economy

This article tests for cointegration between unit labor costs and the level of product prices in four sectors of the U.S. economy: the aggregate business sector, the nonfinancial corporate sector, durable manufacturing, and nondurable manufacturing. A finding of cointegration for most specifications supports the existence of long-run labor market equilibrium for producers and suggests estimation of error-correction models to examine the dynamic relationships. In every sector except nondurable manufacturing, error-correction model estimates indicate there is a mutual feedback relationship between unit labor costs and prices. Controlling for deviations from full employment, oil price shocks, and the Nixon wage and price controls, the results also provide evidence of significant nominal wage indexation in U.S. labor markets. Throughout the economy there appears to exist both effective neoclassical wage and price adjustment mechanisms to maintain labor market equilibrium and short-run rigidities which may contribute to deviations from full employment outcomes.     

Deposit drains on “interest-paying” banks before financial crises

This paper conducts an econometric test of Diamond and Dybvig’s [Diamond, D., Dybvig, P., 1983. Bank runs, deposit insurance, and liquidity. Journal of Political Economy 91, 401–420] theory of bank runs as interpreted by Chari [Chari, V.V., 1989. Banking without deposit insurance or banks panics: lessons from a model of the U.S. national banking system. Federal Reserve Bank of Minneapolis Quarterly Review 13, 3–19] and Calomiris and Gorton [Calomiris, C., Gorton, G., 1991. Origins of banking panics: models, facts, and bank regulation. In: Hubbard, R.G. (Ed.), Financial Markets and Financial Crises. NBER and Univ. Chicago press, Chicago, pp. 109–173]. We test whether or not seasonal deposit drains on New York banks coincide with the bank panics of 1873 and 1893 in the United States. We use individual bank level data to illuminate the reason for withdrawals. The evidence reveals that the panic of 1873 could have included a seasonal interior drain. A seasonal interpretation of Diamond and Dybvig’s model cannot be applied to the bank panic of 1893.     

Rural to urban land conversion in China — How large is the over-conversion and what are its welfare implications?

The current system of converting farmland to urban land use in China can be characterized as a hybrid system that combines government controls with market-based transfers. In this paper we argue that this hybrid governance structure causes an over-conversion of farmland from the rural to the urban sector, as compared to a competitive market situation, and a welfare reallocation that discriminates against farmland owners. We develop a partial equilibrium model that can be used to examine the impact of the current hybrid governance structure on the over-conversion of farmland and to analyze the welfare changes for different groups of actors and the resulting net social welfare loss. Using a dataset with detailed information on farmland acquisitions and urban land transactions in Yingtan City in Jiangxi Province, we illustrate how this framework can be applied. Our results indicate an over-conversion of 33.5% of the total converted farmland in this city between 1999 and 2003. The welfare of farmland owners affected by the conversion decreased by 1.38 billion RMB, while the net social welfare loss equaled more than 270 million RMB during the same period. The local government obtained 380 million RMB of revenues by re-selling farmland as urban land through competitive conveyance mechanisms between 2002 and 2005, while the manufacturing sector gained an estimated 280 million RMB from buying land use rights at relatively low prices. We conclude that the current policy of increasing urban land conveyance through competitive mechanisms does not address two major underlying causes of over-conversion, and that protection of farmland would be better served by replacing the current hybrid rural to urban land market structure by a competitive land market.     

What happens to land price when a rural construction land market legally opens in China? A spatiotemporal analysis of Nanhai district from 2010 to 2015

Urban and rural construction land markets in China, the two formerly separated markets, are beginning to be unified in some pilot areas. So far, but little is known about the associated land market development patterns and what factors influence land market price. In order to examine the impact of urban developers' access to legal rural construction land market on land price, we analyzed the spatiotemporal heterogeneity of price trends for the rural-urban land market in Nanhai district, Guangdong Province, between 2010 and 2015. We collected 2285 land transaction data during that span and mapped price contour lines for the rural-urban development land market in the whole district by using spatial interpolation techniques. Four hedonic price models, on rural and urban construction land respectively, were developed to measure the marginal effects of land attributes on price. Results from the analysis suggest that, temporally, the prices of rural-urban development land grew rapidly between 2010 and 2015. Spatially, prices spread along a gradient from east to west, and the prices in North Nanhai district were significantly higher than those in the south. The hedonic models also suggest that land use type, lot size, and various spatial characteristics impact rural and urban land prices. Overall, this research presented here contributes our understanding of the complex nature of establishing a unified land market in China.     

PPP: <Emphasis Type="Italic">Delusion</Emphasis> or <Emphasis Type="Italic">Reality</Emphasis>? Evidence from a Nonlinear Analysis

In this paper we analyze the validity of the purchasing power parity (PPP) in a nonlinear framework using data for 18 bilateral US dollar exchange rates. Following Enders and Ludlow (2002), we use unit root and cointegration tests that do not assume a specific nonlinear adjustment. We find evidence of non-linear mean reversion in deviations from the PPP equilibrium in 11 out of 18 currencies. Additionally, to disentangle the respective contribution of exchange rate and prices to the adjustment toward the long run equilibrium, we estimate a Vector Error Correction Model. According to our empirical analysis, there exists a nonlinear mechanism to correct for deviation from the PPP equilibrium that comes mainly from the exchange rates. This is consistent with theoretical arguments on international goods markets under transaction costs as well as with an emerging strand of empirical literature. These results highlight the importance of neglecting the possibility of nonlinearity in the debate about the PPP and provide empirical evidence that supports the scenario of the PPP hypothesis as a reality.     

The relative importance of liquidity and other constraints inhibiting the growth of small‐scale farming in KwaZulu‐Natal

A logit model is used to examine the extent of liquidity constraints relative to other constraints inhibiting small‐scale farming in KwaZulu‐Natal. These other constraints include poor access to land, labour and information, and high transaction costs. Data for the analysis were sourced from two rural districts in the former KwaZulu. The results suggest that liquidity is important, while imperfect land markets, information costs and high transaction costs are also significant inhibiting factors. Investments in literacy and language skills, vocational training, and business and financial management skills may improve income opportunities for rural people and hence enhance their ability to invest, save and borrow. Better roads, telecommunications and legal institutions are also required to realise the full benefit of investment in extension and credit services.     

MODELLING INFLATION IN SOUTH AFRICA: A MULTIVARIATE COINTEGRATION ANALYSIS

We employ an expectations augmented Phillips curve framework to investigate the link between inflation, unit labour costs, the output gap, the real exchange rate and inflation expectations. Using multivariate cointegration techniques, we find evidence consistent with mark‐up behaviour of output prices over unit labour costs. Most importantly, we find that the mark‐up in the South African economy is much higher than in the U.S. For South Africa we find a markup of about 30 per cent: three times as high as the 10 per cent markup found for the U.S.     

Transaction costs and crop marketing in the communal areas of Impendle and Swayimana,KwaZulu-Natal

High transaction costs are detrimental to the efficient operation or existence of markets for inputs and outputs. The cost of information and the costs associated with the search for trade partners, the distance to formal markets and contract enforcement are likely to influence the marketing of food crops. This study hypothesises that the level of income generated from food-crop sales by small-scale farmers in the Impendle and Swayimana districts of KwaZuluNatal is influenced by transaction costs and certain household and farm characteristics. Regression analysis shows that the depth of marketing methods is significantly influenced by transaction cost proxies, such as cooperation with large commercial farmers and ownership of means of transport. Results from a block-recursive regression analysis show that the level of crop income generated is determined by the depth of marketing methods, the size of allocated arable land and off-farm income. Households with lower transaction costs, sizeable allocated land and off-farm income can be expected to generate higher income from food crops. Investment in public goods such as roads, telecommunications and an efficient legal system (to uphold commercial contracts), as well as farmer support services (input supply, extension, marketing information and research), would probably raise farm and non-farm income by reducing transaction costs. This would increase the effective demand for locally produced goods and services, thus contributing to rural employment and livelihoods within rural communal areas.     

Efficiency and equity gains in the rental market for arable land: observations from a communal area of KwaZulu-Natal,South Africa

Between 1993 and 1996, Thomson made a concerted effort to stimulate a rental market for arable land in the Upper Tugela Catchment region of the former KwaZulu homeland, South Africa. The number of transactions increased with associated gains in equity and efficiency. This study revisits the market and examines its performance in the year 2000. It was found that the number of rental transactions and lessees had declined, but that the area of land transacted had increased sharply. This apparent anomaly can be explained by an increase in fixed transaction costs that prevented prospective participants from entering the market, and a decrease in variable transaction costs that encouraged lessees to trade larger areas. Lessees are consolidating land from several different lessors, with gains in equity and efficiency still evident. Government extension staff could play a key role in sustaining and broadening access to rental markets for cropland in communal areas by reducing fixed transaction costs as Thomson did.     

The “news view” of economic fluctuations: Evidence from aggregate Japanese data and sectoral US data

This paper uses aggregate Japanese data and sectoral US data to explore the properties of the joint behavior of stock prices and total factor productivity (TFP) with the aim of highlighting data patterns that are useful for evaluating business cycle theories. The approach used follows that presented in [Beaudry, P., Portier, F., 2004. News, stock prices and economic fluctuations. Working paper 10548. NBER]. The main findings are that (i) in both Japan and the US, innovations in stock prices that are contemporaneously orthogonal to TFP precede most of the long-run movements in total factor productivity and (ii) such stock prices innovations do not affect US sectoral TFPs contemporaneously, but do precede TFP increases in those sectors that are driving US TFP growth, namely durable goods, and among them equipment sectors.

Oil and gold price dynamics in a multivariate cointegration framework

This study delivers further insights into oil and gold price dynamics and their relation to U.S. prices and the dollar exchange rate. Previous studies have frequently analyzed this issue regarding the price either of gold or of oil; however, the role of both quantities has not been analyzed simultaneously in a broader context. To tackle this caveat, we use monthly data for the nominal effective dollar exchange rate, oil, gold and U.S. prices from 1976:01 to 2011:11. We carefully analyze the long-run as well as the short-run dynamics and the long-run impact in terms of shocks, applying a cointegrated VAR model. The main conclusion we reach is that although gold and oil are both important commodities, their economic impact in terms of their shocks differs significantly. In the long-run, both quantities seem to be positively related and shocks to the gold price drive the system. In addition, the gold-oil spread is positively related to U.S. consumer prices, which implies a stronger relationship of consumer prices to the former.     

Relating Product Prices to Long‐Run Marginal Cost: Evidence from Solar Photovoltaic Modules

A basic tenet of microeconomics is that for a competitive industry in equilibrium the market price of a product will be equal to its marginal cost. This paper develops a model framework and a corresponding empirical inference procedure for estimating long‐run marginal cost in industries where production costs decline over time. In the context of the solar photovoltaic (PV) module industry, we rely primarily on firm‐level financial accounting data to estimate the long‐run marginal cost of PV modules for the years 2008–2013. During those years, the industry experienced both unprecedented price declines and significant expansions of manufacturing capacity. We compare the trajectory of average sales prices with the estimated long‐run marginal costs in order to quantify the extent to which actual price declines were attributable to reductions in production costs. The trajectory of estimated product costs is then extrapolated to forecast an equilibrium trend line for future PV module prices.
