On the Relative Optimality of Environmental Policy Instruments: An Application of the Work of Alberto Alesina

We study the issue of optimality of policies devoted to environmental goals, building upon the recent and interesting work by Alesina and Passarelli (2010) and extending their analysis to the more general framework set up by Weitzman (The Review of Economic Studies 41: 477-491, 1974). We illustrate instruments that governments have at their disposal to reduce polluting emissions, and we point out the economic implications that may arise from the overlapping regulation through both instruments in the European context. We review the literature on political determination of environmental regulation. On the basis of existing literature, we show that political factors are more important than economic ones in explaining why particular instruments are implemented for certain problems (Hepburn et al. Climate Policy 6: 137–160, 2006). We recognize Alesina’s contribution which states that environmental policy, and the decision to adopt one tool instead of another, is subject to a complex political process. Governments are subject to pressure from politicians, households, and firms because their decisions imply winners and losers. Then, we focus in detail on the work by Alesina and Passarelli (2010) who consider which policy tool and at what level would be chosen by majority voting to reduce polluting emissions; they find out that even if a tax is in general superior to quantity based mechanisms (quotas and tradable permits), the majority may strategically choose a quantity mode in order to charge the minority a larger share of the cost for polluting emissions reduction. We extend Alesina’s analysis, focusing on the optimality of price-based mechanisms, since it is not always the case that price instruments are more efficient than quantity instruments. To this aim, we explicitly make use of Weitzman results (The Review of Economic Studies 41: 477–491, 1974), which suggest that if costs are highly nonlinear compared to benefits, then price-type regulation is more efficient, while if costs are close to linear, then quantity-type regulation is more efficient. We cast Alesina’s analysis in the European context, analyzing potential voting outcomes, assuming that EU countries can be arranged according to different criteria. We find that depending on the empirical distribution of voting countries, Alesina’s voting procedure leads to interesting different outcomes.     

Production versus distribution-oriented FDI

The business literature has long recognized the importance of multinationals’ distribution networks. The empirical analysis of distribution-oriented FDI has, however, received little attention which is at least partly due to the lack of appropriate data. We present a slightly modified version of Helpman et al. (Am Econ Rev 94(1):300–316, 2004) that explicitly models the possibility for a multinational firm to export through its wholesale trade affiliate. We analyze the multinational firms’ choice between foreign production and foreign distribution. Our empirical analysis uses different discrete choice models and alternative specifications for several sub-samples of multinational firms. Our results show that the choice between distribution and production-oriented FDI is based on the trade-off between fixed and variable costs.     

The Whiter the Better? Racial Composition and Access to School Resources for Black Students

Rigorous courses are an important resource, distributed within schools, that merit attention as a central determinant of student achievement and future outcomes (Cook and Evans, J Labor Econ. 18(4):729–754, 2000; Rose and Betts, Rev Econ Stat. 86(2):497–513, 2004). Yet, black students are less likely to be enrolled in advanced courses in general (ex. Darity et al. 2001; Klopfenstein, Contemp Econ Pol. 23(3):416–28, 2005) and specifically Algebra 1 in middle school (Riley 1997). Debate exists around the potential benefits or drawbacks for black students attending highly integrated schools relative to highly segregated schools. This study examines which school characteristics are associated with large disparities in black student enrollment in Algebra 1 relative to white student enrollment in Algebra 1 in the same middle schools in North Carolina. Of particular interest is the relationship between access and the percentage of white students in a school. The study finds that: (1) black students are underrepresented in Algebra 1 in essentially all schools in North Carolina; (2) the largest disparities occur in schools that are highly integrated while the disparities are reduced in schools that are either large majority white or large majority non-white; (3) schools with a larger share of white teachers are related to larger disparities between black and white students; (4) the marginal effects of racial composition on the relative disparity in enrollment are significantly larger for black females than black males.     

Heterogeneous Productivity and the Gains from Trade and FDI

Nontraded goods account for a major share of GDP in most economies, but have not been incorporated in the welfare analysis of monopolistic-competition models with heterogeneous productivity. This paper extends Helpman, Melitz and Yeaple (American Economic Review 94(1):300–316, 2004) to explore welfare effects in the presence of a nontraded good. We derive new analytical results about how the gains from trade and FDI are determined and affected by key parameters in the case of symmetric countries. The model is calibrated to a country group that includes all major developed countries. The gains from openness (trade and FDI) are found to be substantial (between 3.24 and 6.27 per cent of income) even if nontraded goods represent a major part of the economy. Most of these gains are attributed to trade rather than FDI.     

Cointegration tests of purchasing power parity

Im et al. (Unpublished working paper, 2008) develop cointegration tests using stationary instrumental variables. Their tests avoid the need to simulate critical values for the cointegration estimations, especially problematic in the presence of a nuisance parameter. Likewise, bootstrapping errors is unnecessary. Using an updated version of the Taylor (Rev Econ Stat 84(1):139–150, 2002) data set, the Im et al. (Unpublished working paper, 2008) approach is applied to two well-known, single equation cointegration methods to test for purchasing power parity. The estimations with instruments provide evidence of purchasing power parity (PPP) for more than half of the countries studied; but the empirical results, hence conclusions regarding PPP sometimes differ with the choice of instrument.     

For Colored Girls? Factors that Influence Teacher Recommendations into Advanced Courses for Black Girls

Given the lack of attention to Black girls’ participation in STEM related courses, it remains unclear why this group participates at lower rates in STEM courses later in their academic careers (Hyde et al. 2008; Tocci and Engelhard 1991; Catsambis 1994). The purpose of this paper is to examine the extent to which teachers influence Black girls’ opportunities along the math pipeline. The aim is to determine the role of Black girls’ cognitive and non-cognitive behaviors on teachers’ decisions to place them in advanced courses. Using nationally representative survey data, the findings indicate that Black girls’ confidence in their ability to master skills taught math reduced the odds teacher recommendations to advanced courses. Additionally, teachers’ expectations of the educational attainment of Black girls were related to the recommendation process. Overall, the findings suggest that subjective beliefs held by students and teachers critically influence Black girls’ persistence along the math pipeline.     

The Dollar-Pound Exchange Rate During the First Nine Months of World War II

Between August 25, 1939 and June 7, 1940, there was a free market for British pounds in New York. German success at the outset of World War II caused the value of free sterling to fall relative to the official exchange rate. This imposed an externality that made it more difficult for Britain to finance the war. Eventually, the externality became large enough that Britain chose to take extreme measures to abolish it, even at the expense of tarnishing the reputation of London’s financial markets. We collected daily data to investigate how the market reacted to war news and to policy changes. Using methods developed by Bai and Perron (Econometrica 66:47–78, 1998; Journal of Applied Econometrics 18:1–22, 2003), we find 17 breaks in the exchange rate. Fourteen are associated with military events and three are associated with policy changes. The episode illustrates how markets can fail to serve the public interest during times of war.     

Third-Degree Price Discrimination: Apology not Necessary _ Comment

In this comment, we note that the analysis in Lopez and Molina (2010) is subject to a number of mistakes and various unjustifiable assumptions.     

An Empirical Analysis of the Austrian Business Cycle Theory

The Austrian economists Ludwig von Mises and Friedrich A. Hayek developed a unique theory of the business cycle. In their view, an unsustainable boom ensues when the rate of interest prevailing in the market falls below the natural rate. The boom is characterized not only by an increase in aggregate production but also by a distortion of the structure of production. Similarly, the recession that follows is characterized by a decline in aggregate production as the structure of production is repaired. Hence, the Austrian account of macroeconomic fluctuation stresses the misallocation and reallocation of resources in addition to the overproduction and underproduction of more conventional business cycle theories. In a recent article, Lester and Wolff (Review of Austrian Economics 26(4):433–461, 2013) attempt to consider the empirical relevance of the Austrian view. We argue that the authors’ use of the federal funds rate as an indicator of monetary policy is inappropriate in that it fails to distinguish a low market interest rate from a market interest rate that is low relative to the natural rate. Using an estimate of the natural rate provided by Selgin et al. (2011), we attempt to improve upon their analysis.     

The Non-Monetary Side of the Global Disinflation

The dramatic decline in inflation across the world over the last 20 years has been largely credited to improved monetary policy. The universal nature of the phenomenon, however, indicates that globalization, which occurred simultaneously, also played a role. We build a model based on Melitz (2003) in which falling transport cost lead to greater openness, higher productivity and lower inflation. Following a decline in transport cost openness increases and firm selection eliminates the least productive domestic firms. The consequent increase in average productivity leads to falling relative prices for goods. A cash-in-advance constraint allows analyzing how falling relative prices can lead to lower inflation. Using a data set of macroeconomic variables for 123 countries from all world regions, we disentangle the influences of monetary policy and globalization by showing that openness-induced productivity growth leads to a significant decline in inflation world-wide. The results can be further confirmed in a calibration exercise.     

The Entrepreneur: Real and Imagined

Ludwig von Mises, Friedrich Hayek, and Murray Rothbard were the main architects of the distinctly Austrian theory of production as it exists today. All three conceived the entrepreneurial function in the actual market economy as presupposing the ownership of property, specifically capital. Yet, many, if not most, contemporary Austrian economists conceive the entrepreneur as a pure decision-maker possessing superior “alertness” but owning no resources. This pure entrepreneur earns profits by “discovering” and seizing objectively existing but previously unperceived opportunities to arbitrage price discrepancies between a bundle of complementary inputs and the output it yields. That this is the essence of “the” Austrian theory of the entrepreneur and profit is accepted as a matter of course by those among the broader economics profession who are sympathetic to the Austrian approach. It is the goal of this paper to demonstrate that there is in the Austrian tradition traceable back to Carl Menger, a very definite and prominent strand of thought that conceives property ownership as central to the tasks that the entrepreneur characteristically performs in the real-world market economy. The managerial function . . . can never evolve into a substitute for entrepreneurship. The fallacy to the contrary is due to the error confusing the category of entrepreneurship as it is defined in the imaginary construction of functional distribution with conditions in a living and operating market economy. The function of the entrepreneur cannot be separated from the direction of the employment of factors of production for the accomplishment of definite tasks. The entrepreneur controls the factors of production; it is this control that brings him either entrepreneurial profit or loss. (Mises 1998, p. 302) Mr. Keynes obviously arrives at this view by an artificial separation of the function of the entrepreneurs as owners of capital and their function as entrepreneurs in the narrow sense. But these two functions cannot be absolutely separated even in theory, because the essential function of the entrepreneurs, that of assuming risks, necessarily implies the ownership of capital. Moreover, any new chance to make entrepreneurs’ profits is identical with a change in the opportunities to invest capital, and will always be reflected in the earnings (and value) of capital invested. (Hayek 1931, p. 277; emphasis in original) It is clear, therefore, that the process of equalization of rate of return throughout the economy, one that results in a uniform rate of interest, is the very same process that brings about the abolition of profits and losses in the ERE. . . . [I]f the . . . entrepreneur owns no assets, then how in the world does he earn profits? Profits, after all, are simply the other side of the coin of an increase in the value of one’s capital; losses are the reflection of a loss in capital assets. (Rothbard 2004, pp. 513–14; 1997, 2:247; emphasis in original)      

Reconsidering learning by exporting

Self-selection and learning by exporting are the main explanations for the higher productivity of exporting firms. But, whereas evidence on self-selection is largely undisputed, results on learning by exporting are mixed and far from conclusive. However, recent research by De Loecker (J Int Econ 73(1):69–98, 2007) has shown that the conclusions from previous learning by exporting studies may have been driven by strong assumptions about the evolution of productivity and the role of export status. Relaxing these assumptions turns out to be critical to find evidence of learning by exporting in a representative sample of Spanish manufacturing firms. Our results indicate that the yearly average gains in productivity are around 3 % for at least 4 years.     

The exporter productivity premium along the productivity distribution: evidence from quantile regression with nonadditive firm fixed effects

A vast literature on the international activities of heterogeneous firms finds the existence of a positive exporter productivity premium. On average, exporting firms are more productive than firms that sell on the national market only. The Melitz (Econometrica 71:1695–1725, 2003) model, however, has implications for not only mean differences but also differences in the distribution of productivity. Furthermore, exporting firms may be different from non-exporting firms for reasons that are not included in the Melitz model. We believe that conditioning on firm fixed effects and studying the distribution of productivity are both necessary for empirical tests of the Melitz model. This paper is the first to employ a new quantile estimation technique for panel data introduced in Powell (Did the economic stimulus payments of 2008 reduce labor supply? Evidence from quantile panel data estimation. RAND Corporation Publications Department, Santa Monica, 2014). We find that the premium is positive at all productivity levels, but highest at the lowest quantiles. These results support theoretical models which suggest that there is a division in productivity between exporters and non-exporters.     

The gains from variety in the European Union

Over the last decade, European Union members have experienced a steady increase in imports. This increase was accompanied by a strong growth in the number of imported goods and trading partners, suggesting positive welfare gains for consumers via an extended set of consumption possibilities, as pointed out in the ??New Trade Theory??. In this paper, we apply the methodology developed by Feenstra (Am Econ Rev 84(1):157?C177, 1994) and Broda and Weinstein (Q J Econ 121(2):541?C585, 2006) to structurally estimate the gains from imported variety for the 27 countries of the European Union using highly disaggregated trade data at the CN-8 level from Eurostat for the period from 1999 to 2008. Our results show that, within the European Union, especially ??newer?? and smaller member states exhibit high gains from newly imported varieties. Furthermore, we find that the majority of the gains from variety for consumers stems from intra-European Union trade.     

How does taste and quality impact on import prices?

Understanding the dynamics of import prices is an important but challenging issue that affects our assessment of welfare. We propose an exact import price index by extending the analysis of Broda and Weinstein (Q J Econ 121(2):541–585, 2006), who include growth in product variety in their calculations of import prices. While still relying on Armington’s (Int Monet Fund Staff Pap 16(1):159–178, 1969) definition of variety, we relax two assumptions, allowing the set of products and unobserved taste and quality parameter to vary. Our modified import price index shows that gains from variety in European G7 countries, although positive, are small compared with gains from taste and quality. Using food and tobacco products as a benchmark with unchanged taste and quality, we find significant gains from shifts in consumer preferences and improving quality for Germany, France, Italy and the UK between 1995 and 2012. By comparing results based on different benchmark groups we further flag the importance of consumer taste in international trade.     

Alchian and Allen Revisited: Law Enforcement and the Price of Weed

Alchian and Allen (1964) theorized that the imposition of a fixed fee or a unit cost in a market with multiple quality grades of the good would encourage consumption of the higher quality grades. Using newly available data on marijuana prices by state, we empirically test the hypothesis that the price of higher quality marijuana will be higher in states with more strict enforcement of marijuana possession laws. Consistent with the Alchian-Allen theorem, the relative price of both medium- and high-quality marijuana are found to be greater in states with stricter law enforcement, suggesting an increase in demand for such varieties.     

Does foreign direct investment cause long run economic growth? Evidence from the Latin American and the Caribbean countries

The empirical evidence about the temporal precedence between foreign direct investment (FDI) and economic growth in open developing economies is mixed. In this research effort, we explored the FDI-growth nexus for 16 developing countries of Latin American and the Caribbean countries during the last three decades, a period in which many of these countries introduced various economic and financial reforms. As a departure from many previous studies, the current analysis uses the Granger noncausality test procedure recently developed by Toda and Yamamoto (J Econ 66:225–250, 1995), and Dolado and Lutkepohl (Econ Rev 15:369–386, 1996)–TYDL. Our results suggest that the null hypothesis that ‘FDI does not Granger cause economic growth’ is rejected for all countries except Dominican Republic, Trinidad and Tobago, and Jamaica. There is also evidence of unidirectional causality from growth to FDI for all countries except Bolivia, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, and Jamaica. We found bidirectional causality for Argentina, Brazil, Mexico, Peru and Venezuela.     

Testing for parameter stability in DSGE models. The cases of France,Germany, Italy,and Spain

We estimate a New Keynesian DSGE model on French, German, Italian, and Spanish data. The main aim of this paper is to check for the respective sets of parameters that are stable over time, making use of the ESS procedure (“Estimate of Set of Stable parameters”) developed by Inoue and Rossi (Rev Econ Stat 93(4):1186–1204, 2011). This new econometric technique allows to address the stability properties of each single parameter in a DSGE model separately. In the case of France, Germany, and Italy our results point to structural breaks after the beginning of the second stage of EMU in the mid-nineties, while the estimates for Spain show a significant break just before the start of the third stage in 1998. Specifically, there are significant changes in monetary policy behavior for France, Italy, and Spain, while monetary policy in Germany seems to be stable over time.     

The Political and Economic Dimension of Monetary Unions

This paper investigates the relationship between the political and economic aspects of monetary unions. After illustrating the recent change in approach to the theory of optimum currency areas (section 2), the paper analyzes the momentous implications of union members maintaining political sovereignty (section 3) for the notion of currency area optimality and the viability of monetary unions (section 4).     

Elasticity of substitution and anti-dumping decisions

Motivated by a monopolistic competition model with market segmentation and international price discrimination, this paper analyzes whether there is an inverse relation between the elasticity of substitution and final ad valorem anti-dumping duties across products. We test this for 19 countries using data on anti-dumping from the Global Antidumping Database and US data at the 6-digit HS product level for the elasticity of substitution from Broda and Weinstein (Q J Econ 121(2):541–585, 2006). The results in our empirical investigation support a negative relation between the elasticity of substitution and the final ad valorem anti-dumping duties.
