Measuring embodied technical change in the US local telephone industry

This study attempts to measure the rate of embodied technical change by using a short-run variable cost function that contains arguments for labour and capital quality. In this short-run variable cost model, the expansion of the amount of physical capital increases variable costs due to more maintenance outlays, and then it leads to improvements in capital quality. When a measure of competition is included as a proxy for organizational efficiency, improvements in labour and capital quality explain more than two-thirds of productivity growth. The degree of returns to scale and the shadow cost of capital input in the embodiment cost model are presented as well. The study is based on pooled time-series and cross-section data of eight US local exchange carriers.     

How responsive are trade flows between Malaysia and China to the exchange rate? Evidence from industry data

This paper investigates the impact of currency depreciation on bilateral trade between Malaysia and China, especially how a real depreciation of ringgit against the yuan on each industry’s inpayments and outpayments affect the trade balance. We employ disaggregated quarterly data on import and export for 52 industries over the period 1993Q1 to 2012Q4. The results from the bounds testing approach to the cointegration and error-correction model reveal that the real bilateral exchange rate has short and long-run effects on the inpayments and outpayments of the industries. However, the short-run effects shift into the long run in 14 out of 35 industries in the inpayment models and 17 out of 44 industries in the outpayments models. Most of these are small industries producing intermediate goods. According to the ML condition, the depreciation of ringgit against yuan improves Malaysia’s trade balance with China in these industries.     

Characterizing the Vickrey combinatorial auction by induction

This note studies the allocation of heterogeneous commodities to agents whose private values for combinations of these commodities are monotonic by inclusion. This setting can accommodate the presence of complementarity and substitutability among the heterogeneous commodities. By using induction logic, we provide an alternative proof of Holmstrom’s (Econometrica 47:1137–1144, 1979) characterization of the Vickrey combinatorial auction as the unique efficient, strategy-proof, and individually rational allocation rule on a smoothly connected domain of value profiles. Our approach is elementary, not involving smoothness, and intuitive in the sense that familiar properties of the single-item second-price auction provide the first step in our induction on the number of auctioned items. Moreover, our method of proof can be applied to domains which may not be smoothly connected, including nonconvex ones. The authors acknowledge the helpful comments of anonymous referee.

The Impact of Housing Prices on Health in the United States Before,During, and After the Great Recession

We estimate the effects of U.S. Metropolitan Statistical Area housing prices on a variety of health outcomes and health-related behaviors separately for homeowners and tenants. The constructed data set consists of information on individuals from the 2002–2012 Behavioral Risk Factor Surveillance System combined with homeownership data from the March Current Population Survey and housing prices from Freddie Mac. We estimate positive effects on homeowners' mental health when housing prices increase. We also find negative effects on tenants' health and health-related behaviors with increases in housing prices. These estimated contemporaneous effects are concentrated among low-income homeowners and tenants, and the effects for tenants are not persistent in the long run. However, the cumulative effects of an increase in housing prices on obesity become more pronounced for homeowners in the long run, resulting in worse self-reported health.     

The Impact of Information Release on Stock Price Volatility and Trading Volume: The Rights Offering Case

This paper examines whether information released via rights offering announcements induces changes in price volatility and trading volume of underlying stock. The results of this paper provide support for the release of new information via offering announcements and evidence of its effects on price volatility and volume of underlying stock. Specifically, utilization of the announced information by investors is evidenced by greater trading volume following the announcement date than during the pre-announcement period. We interpret this result to mean that informedness dominates consensus. However, stock price volatility decreased from the pre-announcement period to the post-expiration period of rights offerings.     

The early exercise premia of America put options on stocks

Using the put-call parity, this paper finds that early exercise premia of short-lived American put options on stocks account for a significant portion of put prices. This finding holds even for out-of-the-money put options. The magnitude of the early exercise premia of American put options with no dividend is positvely related to the degree of moneyness, time to maturity of the put option, and the volatility. The magnitude of the early exercise premia of American put options with dividend is positvely related to the degree of moneyness and the risk-free interest rates.     

Corporate Tax Aggressiveness and Insider Trading

We examine the association between corporate tax aggressiveness and the profitability of insider trading under the assumption that insider trading profits reflect managerial opportunism. We document that insider purchase profitability, but not sales profitability, is significantly higher on average in more tax aggressive firms. We also find that the positive association between tax aggressiveness and insider purchase profitability is attenuated for firms with more effective monitoring and is accentuated for firms with a more opaque information environment. In addition, we provide empirical evidence that tax aggressiveness is significantly associated with greater insider sales volume in the fiscal year prior to a stock price crash. Finally, we find that the association between tax aggressiveness and insider purchase profitability weakens after the introduction of FIN 48, consistent with the increased transparency of tax positions under the new disclosure requirement reducing insiders' information advantage and hence their ability to profit from insider trading. To the extent that insider trading profits reflect managerial opportunism, our results are consistent with managers exploiting the opacity arising from tax aggressive activities to extract rent from shareholders, particularly those shareholders who sold their shares to the managers. Our findings are particularly important in light of the number of studies relying on the agency view of tax avoidance to develop arguments or to draw inferences.     

Competition policy in Indonesia: Conglomerates versus SMEs1

Since the currency crisis, Indonesia has undergone rapid economic and political changes. However, the IMF‐directed recovery program, such as decentralization, does not seem successful. Despite the improvised legal system, the implementation of the recovery program is very poor. Lack of consensus on the role of conglomerates and the direction of competition policy, has prevented Indonesia from recovery. Anti‐conglomerate sentiment of the post‐Suharto times has given rise to unbalanced competition law and inconsistency among related laws. Treatment of the banking sector including ownership is a critical factor in the recapitalization process. Due to the similarity between Indonesia and Korea, Korean experiences would help Indonesia to establish the principles on competition policy. The separation principle is strongly recommended for Indonesia at the current development stage, and it is urgent to establish a rule‐based, not a discretion‐based, economy. The problems of conglomerates should be resolved through comprehensive competition policies.     

The role of the state in skill formation: evidence from the Republic of Korea, Singapore, and Taiwan

We propose a new interpretation of the role of the state inskill formation, with reference to three East Asian newly industrializedeconomies. Rather than see the state as simply redressing externalities,we interpret the state as matching the supply and demand forskills in a rapidly growing economy. This role can be superiorto a strategy of allowing education and training institutionsto be driven by autonomous processes. The role is most likelyto be observed in developmental states. We examine the politicalmechanisms that have helped to ensure that educational and trainingpolicy formation are subordinated to the imperatives of economicgrowth. While the East Asian model cannot be imported wholesaleto western countries such as Britain in different historicalcircumstances, the example lends credence to the value of thestate taking a strategic approach to education and trainingpolicy.
