Information technology and economic performance in U.S industries

Abstract .  We study the relationship between information technology (IT) and economic performance, to explore whether IT-capital promotes productivity growth. We use a data set similar to that of previous researchers, but employ non-parametric estimation techniques in order to directly estimate the output elasticities of IT for each industry and time period. We find that IT has a positive effect on productivity, which varies among industries and time. Moreover, adjustment costs are important when identifying this effect. Finally, IT-capital growth appears to be raising income in all industries used in our sample, even those that experienced output reduction.     

Political regime type and variation in economic growth rates

Research about the effects of regime type on economic growth rates did not establish any robust differences in average growth rates between democracies and autocracies. Here, it is suggested that we may have asked the wrong question. There still might be a difference in variances. Democracy implies similar constraints on rulers and thereby might lead to quite similar economic performances. Among autocracies, however, constitutional and institutional constraints are likely to be weak and variable. Moreover, personal inclinations of autocrats might matter much more than personality differences between democratic rulers. Data from the 1960–87 period supply some evidence that there is indeed greater variation in growth rates among autocracies than among democracies.     

Emerging from the Hobbesian jungle: Might takes and makes rights

The conflict over scarce resources in the Hobbesian jungle may be avoided if rules of obligation delineating property rights develop along with institutions of governance. One possibility is a “duress contract” as the strongest individual threatens others who agree to enslavement. Thus, “might takes rights.” Alternatively, individuals with similar capacities for violence may enter a “consent contract” establishing rules of obligation and then voluntarily participating in governance. They will not agree to a rights assignment that produces less wealth than they expect through violence, however, so “might makes rights.” A might-takes-and-makes-rights analysis is outlined to explain the continuum of legal institutions and property rights allocations that can evolve between these two extremes of duress and consent. Increasingly finely delineated private property rights tend to evolve under institutions produced by consent contracts, while common pool problems tend to arise near the duress contract end of the spectrum. This paper draws from a larger project on “The Evolution of Law” which has been supported by the Earhart Foundation. Discussions with and comments by Randy Holcombe, Kevin Reffit, and two anonymous referees led to significant improvements in the development and presentation of the arguments, as did discussant comments on a related paper made by Douglas Ginsburg and participants in the Friedrich August von Hayek Symposium on “Competition Among Institutions” in Freiburg, Germany, June 1–4, 1994, sponsored by the International Institute at George Mason University and the Walter Eucken Institute, Freiburg.     

Nonlinear economic growth: Some theory and cross-country evidence

This paper aims to test the existence of different growth regimes, that is of different relationships between growth rate and income level. We propose a simple nonlinear growth model and test its empirical implications by estimating Markov transition matrices and stochastic kernels. We show that growth is indeed nonlinear: a first phase of slow or zero growth is followed by a take-off and, finally, by a phase of deceleration. We discuss the relevance of these results with respect to the issue of convergence and reversibility of development, in the light of models of structural change and technological diffusion.     

U.S. industry-level returns and oil prices

This paper empirically investigates and provides further support for the oil price effect documented in Driesprong et al. (2008) in the U.S. industry-level returns. We find that oil price predictability is concentrated in a relatively small number of industry-level returns, the relevant measure for a study of the oil effect is percentage change in oil spot prices, and changes in oil futures prices have virtually no prediction power for industry-level returns. With percentage changes in oil spot prices as the predictor, approximately one fifth of industry returns are oil-predictable. We detect a two trading weeks delay in reaction to oil price changes which is consistent with the Hong and Stein (1996) underreaction hypothesis. These results are robust to various alternative specifications, and are shown to be unrelated to time-varying risk premia. Moreover, we demonstrate that trading strategies based on the oil effect generate superior gains in comparison with buy-and-hold strategy in the presence of reasonable trading costs.     

Property rights protection and corporate R&D: Evidence from China

Following the recent literature on institutions and economic growth, we examine the effects of property rights protection on corporate R&D. Using a unique 2003 World Bank survey of over 2400 firms in 18 Chinese cities, we obtain the following findings: (1) property rights protection is positively and significantly related to corporate R&D activity (for both process and product R&D); (2) government services and helping hand are conducive to corporate R&D, while informal payments to government officials are not; and (3) government ownership of firms and direct appointment of CEOs are negatively associated with corporate R&D activities. We also find that corporate R&D is positively related to firm size, and access to finance, but negatively related to product market competition and firm age.     

Political instability: Effects on financial development, roots in the severity of economic inequality

We here bring forward strong evidence that political instability impedes financial development, with its variation a primary determinant of differences in financial development around the world. As such, it needs to be added to the short list of major determinants of financial development. First, structural conditions first postulated by Engerman and Sokoloff (2002) as generating long-term inequality are shown here to have strong empirical support as exogenous determinants of political instability. Second, that exogenously-determined political instability in turn holds back financial development, even when we control for factors prominent in the last decade’s cross-country studies of financial development. The findings indicate that inequality-perpetuating conditions that result in political instability and weak democracy are fundamental roadblocks for international organizations like the World Bank that seek to promote financial development. The evidence here includes country fixed effect regressions and an instrumental model inspired by Engerman and Sokoloff’s (2002) work, which to our knowledge has not yet been used in finance and which is consistent with current tests as valid instruments. Four conventional measures of national political instability – Alesina and Perotti’s (1996) well-known index of instability, a subsequent index derived from Banks’ (2005) work, and two indices of managerial perceptions of nation-by-nation political instability – persistently predict a wide range of national financial development outcomes. Political instability’s significance is time consistent in cross-sectional regressions back to the 1960s, the period when the key data becomes available, robust in both country fixed effects and instrumental variable regressions, and consistent across multiple measures of instability and of financial development. Overall, the results indicate the existence of an important channel running from structural inequality to political instability, principally in nondemocratic settings, and then to financial backwardness. The robust significance of that channel extends existing work demonstrating the importance of political economy explanations for financial development and financial backwardness. It should help to better understand which policies will work for financial development, because political instability has causes, cures, and effects quite distinct from those of many of the key institutions most studied in the past decade as explaining financial backwardness.     

Unbundling democracy: Political rights and civil liberties

Much recent political economy and political science literature views democracy in terms of political rights. This view, often referred to as electoral democracy, is particularly pronounced in the empirical literature. We reincorporate the role of civil liberties, which are at the core of modern democracy, in two ways. We identify four fundamental sources of potential differences in the evolution of political rights and civil liberties. We present systematic, robust and varied empirical evidence on the direct impact of two of these potential sources of differences using cross-national panel data and accounting for the modernization hypothesis. We obtain two noteworthy empirical results: civil liberties exhibit greater persistence than political rights in affecting subsequent outcomes; and, our main result, civil liberties are complementary to political rights when affecting subsequent outcomes, while the reverse is not the case. Consequently, one must incorporate civil liberties as a determinant of electoral democracy. More generally, both dimensions must be considered to understand the setbacks recently experienced by many democracies, despite their holding of free and fair elections.     

A century of economic growth in Latin America

This paper makes a contribution to the study of economic growth in developing countries by analyzing the six largest Latin American economies over 105 years within a two-equation framework. Confirming previous findings, physical and human capital prove to be key determinants of GDP per head growth. However, a more controversial result is an overall negative conditional correlation between trade openness and GDP per head growth — though openness has a positive link via investment. The evidence also shows that macroeconomic instability has been a drag on long-term growth in the region.

The role of importers and exporters in the determination of the U.S. tariff preferences granted to Latin America

This paper investigates the role played by domestic importers and foreign exporters in improving preferential access to the domestic market. To this end, the framework used in this paper extends the protection for sale analysis to explicitly model the role of domestic importers and foreign exporters in the determination of preferential trade treatment. The predictions of the model are tested using data on preferential trade between the United States and Latin American countries. The results suggest that Latin American exporters and US importers' lobbying efforts have a significant and important role in determining the extent of preferential access granted by the United States. More interestingly, these findings also show that U.S. importers capture a very substantial share of the rents generated by tariff preferences. These results therefore shed a pessimistic view on preferential trade schemes as a reliable source of gains for developing countries.     

Experiencing change and the evolution of adaptive skills: Implications for economic growth

We distinguish learning in a static environment from that in a dynamic environment to show the existence of an important interaction between the development of new technologies and human capital accumulation. Because technological progress creates a more dynamic environment, it complements education in the production of human capital by enhancing adaptive skills. Higher levels of adaptability and human capital in turn determine the profitability of new inventions and the incentive to invest in new R&D. Differences in the history of technological progress produce different levels of adaptability and our results suggest why countries that have comparable levels of education and per capita incomes may differ significantly in their growth performance.     

Political credibility and economic growth in less developed countries

While the mainstream of economic development theory focuses on the efficiency of policy measures, the role of the credibility of these measures is rarely analyzed. In this paper we argue that in less developed countries the problem of establishing the credibility of policy measures is at least as important as the problem of choosing the efficient policy solution. We claim that many of the difficulties less developed countries face can be understood in terms of lack of effective control on the discretionary power of governments, which ultimately leads to policies that are not credible. The private sector anticipates large swings in policies and reacts by withholding its resources. Symptoms of these credibility problems in less developed countries include the size of the informal sector, capital flight, and the reluctance of investors to commit capital. All of these reactions contribute to the slow economic growth in these countries. This paper concludes that establishing strategies for the control of state discretionary power is a crucial precondition for overcoming these problems and generating long term economic growth.     

Fertility choice and economic growth: Empirical evidence from the U.S.

This paper provides empirical evidence to support the proposition of Barro and Becker [1989] that fertility depends positively on the world's long-term real interest rates and negatively on real wages in an economy linked to an international capital market. The empirical evidence suggests that there is no long-run relationship among fertility choice, real wages, long-term real interest rates, and output growth in the U.S. over the period 1960–95. However, when estimating a VAR model and employing the variance decomposition analysis and the impulse response functions, the empirical results support the endogeneity of fertility choice and the proposition that real wages, long-term real interest rates, and output growth is related to changes in fertility choice. The empirical results have important policy implications and provide an explanation for the decline of fertility in Western countries mainly in the last three decades.The views expressed in this paper are those of the authors and not those of the Bank of Greece.     

The economic consequences of substituting carbon payments for crop subsidies in U.S. agriculture

There is a growing body of literature on the costs of sequestering carbon. However, no studies have examined the interplay between farm commodity programs and carbon sequestration programs. This study investigates two dimensions of the interaction between farm commodity programs and afforestation programs, using a price-endogenous sector model of agriculture in the United States. First, this study compares the fiscal and welfare costs of achieving specific carbon targets through afforestation, with and without current farm programs. Second, it examines the welfare, fiscal, and carbon consequences of replacing existing farm subsidies, wholly or in part, with payments for carbon. Two approaches, Hicksian and Marshallian, are investigated. In the first, the sector model is used to quantify the carbon consequences and fiscal costs associated with various combinations of farm commodity and carbon sequestration programs that leave consumers and producers in the U.S. agricultural sector no worse off than under existing farm programs. The second approach focuses on the carbon and welfare consequences of various farm commodity and carbon sequestration programs that hold total program fiscal costs constant at current levels. Althouth the methodology and data are applied to the United States, the issues addressed are common in a number of developed nations, particularly within the European Union (EU). Adapting existing sector models in these nations to perform similar analyses would provide policy makers with more precise information about the nature of the trade-offs involved with second-best policies for replacing farm commodity subsidies with tree planting subsidies.The research reported in this paper was partially funded by the United States Environmental Protection Agency under contract number 68W90077.

The U.S. allowance trading system for sulfur dioxide: An update on market experience

In 1990, the U.S. Congress passed legislation that amended the Clean Air Act to create a new program to mitigate the effects of acid deposition in the U.S. through emission reductions of sulfur dioxide (SO₂) and nitrogen oxides (NO_x) at electric utility plants across the country. The SO₂ reductions, totalling a 40% reduction nationally from 1980 levels or a 10 million ton reduction annually, are achieved largely through an emission trading system, the largest program of its kind designed to date. This trading system has the potential to save up to half of the compliance costs associated with more traditional source-by-source emission limit programs.This paper briefly discusses background on the acid rain issue in the United States, and the principal features of the program, including: a permanent cap on utility emissions of SO₂ beginning in 2010, decision to grant up-front allocation of emission credits to reduce individual approvals of trades, the use of continuous emission monitors and automatic penalties to ensure compliance, and integration of the Acid Rain program requirements with other Clean Air Act programs. The paper also discusses the development of the allowance trading market to date, including the types of compliance options chosen and quantity and type of emissions trading being conducted.The U.S. Government right to retain a non-exclusive, royalty free licence in and to any copyright is acknowledged.     

The extent of the market and stages of agricultural specialization

Abstract This paper provides empirical evidence of an U‐shaped causal relationship between the extent of the market (size of the relevant urban market) and the pattern of crop specialization in a village economy. We use the recent two‐stage estimator developed by Lewbel (2012) and exploit heteroscedasticity for identification. The results suggest that the portfolio of crops in a village economy becomes more diversified initially as the extent of the market increases. However, after the market size reaches a threshold, the production structure starts to specialize again. This evidence on the stages of agricultural diversification is consistent with the stages of diversification identified in the recent literature for the economy as a whole and also for the manufacturing sector.
