A Good Walk Foiled: Monopoly Power and Barriers to Entry into the PGA Tour

In order to explore whether the PGA Tour's 2013 qualifications amendments represent a meritocratic evolution or simply a monopolistic barrier to entry, this study compares the results of the 2014 PGA Tour to those of the Web.com Tour. Upon empirical examination of each tour's earnings, scoring characteristics, and course characteristics, we are able to predict the marginal skill differences between players on the two tours. In doing so, we illustrate that sufficiently talented Web.com Tour golfers are being excluded from participation in the PGA Tour. As such, the changes made by the PGA Tour regarding qualification perhaps run counter to welfare maximization in terms of tour participants and fans of professional golf.

Australian Capital City Real House Prices, 1979–1993

Real house prices have increased by 35 per cent in Australian capital cities during the last 15 years, with Brisbane, Canberra, and Sydney experiencing rises of 48 to 61 per cent and Adelaide, Melbourne and Perth having increases of 20 per cent or less. This article estimates a single model for the six cities to explain the divergent real price behaviour over time and space. It is concluded that the fundamental forces driving real house prices are the growth rate in real wage income (primarily due to employment growth) and the growth in population caused by net overseas migration.     

ECONOMIC INTERACTIONS: CHINA VIS-A-VIS HONG KONG

Hong Kong's role has been integral to China's unprecedented economic growth, but privatization ranks first in importance. Another key factor is Beijing's putting economic reform before political reform. Giving democracy to a society in chaos likely makes matters worse. Hong Kong and China both have profited from their partnership. As China has opened up to allow transformation into a market economy, Hong Kong has provided informational impetus for change, a capitalist model to copy, and middleman functions for China to participate in outside-world goods and financial markets. The collapse of Communism in China and elsewhere has increased the supply of cheap labour perhaps by 2 billion. Manufacturing countries with expensive labour and high cost welfare programmes—such as those in the United States, Canada, and Europe—will have difficulty. Capitalists in these countries will do well by investing abroad but not in their own countries. Though wrong in detail, the factor price equalization theorem—that international movement of goods and international movement of factors of production are equivalent—basically is correct. If China continues moving toward privatisation and joining the international community, it will become fiercely competitive, and prospects will be bright for both China and Hong Kong. However, China's recent drift from capitalism clouds those prospects. Fundamentally, three kinds of rights systems exist: (i) a capitalist system, with well defined private property rights, protected by law, where control of resources is based on ownership; (ii) a hierarchical system, such as Communism, where control of resources is based on one's rank in the hierarchy; (iii) a system of corruption, where control of resources is based on bribes and patronage. China rapidly had been making a transition from the second system to the first but recently seems to have derailed into the third. In any case, Communism's collapse is one of the great events in human history. The hero of that event is Deng Xiaoping—not Gorbachev, nor Thatcher, nor Reagan. Hong Kong, by contributing significantly to China's capitalist movement, has led the Communist world to change.     

International transmission of monthly changes in equity values

Our purpose is to answer two questions pertinent to the international transmission of changes in equity values. First, do lead-lag relationships documented in short-horizon (daily) studies continue to hold in longer time (monthly) horizons? Second, does the lead-lag structure remain stable over time? The questions are answered by examining monthly equity returns for nine countries during the 1980s. We find evidence that is somewhat surprising—significant lead-lag relationships among some countries persist in monthly horizons, particularly during the first half of the 1980s. During the second half, the lead-lag relationships are substantially weaker. During the same period, we find that contemporaneous correlations across countries have largely increased, implying greater influence of worldwide factors in determining equity prices.     

Lower Bound Restrictions on Intensities in Data Envelopment Analysis

We propose an extension to the basic DEA models that guarantees that if an intensity is positive then it must be at least as large as a pre-defined lower bound. This requirement adds an integer programming constraint known within Operations Research as a Fixed-Charge (FC) type of constraint. Accordingly, we term the new model DEA_FC. The proposed model lies between the DEA models that allow units to be scaled arbitrarily low, and the Free Disposal Hull model that allows no scaling. We analyze 18 datasets from the literature to demonstrate that sufficiently low intensities—those for which the scaled Decision-Making Unit (DMU) has inputs and outputs that lie below the minimum values observed—are pervasive, and that the new model ensures fairer comparisons without sacrificing the required discriminating power. We explain why the low-intensity phenomenon exists. In sharp contrast to standard DEA models we demonstrate via examples that an inefficient DMU may play a pivotal role in determining the technology. We also propose a goal programming model that determines how deviations from the lower bounds affect efficiency, which we term the trade-off between the deviation gap and the efficiency gap.     

Trading cost expectations: Evidence from S&P 500 index replacement stock announcements

This paper tests the effect on stock value of an expected change in future trading costs. The capitalized value of a reduction in trading costs is hypothesized to increase the stock value, a trading cost effect. Improved liquidity reduces trading costs. Inclusion as an S&P 500 Index replacement stock is an event hypothesized to increase liquidity. We use 114 observations between January 1, 1983 and October 12, 1989 of stocks added to the Index as replacements for stocks removed. The abnormal return of each stock is regressed against the ratio of the bidask spread to the price of the stock, the change in trading volume of the stock, and the open interest in the Index futures contracts at the close of the month prior to the replacement announcement. We find that the positive abnormal returns for replacement stocks are related to increased daily trading volume after inclusion in the Index. Further, the trading cost effect is proportional to percentage bid-ask spreads prior to inclusion. The trading cost effect increases as trading in derivatives of the Index increases. The volume and stock price changes after replacement are not transitory, indicating an improvement in liquidity. Three alternate hypotheses suggested in prior research to explain the abnormal returns for replacement stocks are tested. Testing each of the three models previously considered: price pressure, inelastic demand curves, and information, we find that none can be accepted with statistical confidence. The abnormal returns of Index replacement stocks are consistent with rational pricing of an anticipated reduction in future transaction costs. This anticipated reduction is capitalized in the value of the stock at the time of the replacement announcement. These results are consistent with a trading cost effect.     

Corporate hedging and input price risk

Input price variability is an important source of risk for corporations that process raw commodities. Models of optimal input hedging are developed in this paper based on the maximization of managerial expected utility. The relationship between hedging strategies and output decisions is examined to assess the impact of the ability to set output prices on futures market participation. As a firm's ability to set output prices diminishes in the short run, input futures positions increase although the optimal hedge ratio may either increase or decrease. For a perfectly competitive firm, however, shifts in output price caused by input price changes provide a natural cash market hedge of input price risk and reduce the firm's optimal input futures position.

Jointly Optimal Taxes and Enforcement Policies in Response to Tax Evasion

Assuming the government cannot fully observe either individual types or incomes and jointly picks optimal taxes and audit policies against evasion can significantly alter standard results from optimal income taxation and tax‐evasion models, which treat these separately. We consider this when individuals differ in their risk preferences and incomes. Given the resulting complexity, supplementing analytic results with numerical analysis helps explain the structure of the resulting policies and how they change when the distribution of income or the revenue requirements of the government change. We do this analysis with and without audit errors and with incomes exogenous or affected by occupational choice.
