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.     

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.     

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.     

The impact of market regulations on intra-European real exchange rates

We study the contribution of market regulations to the dynamics of the real exchange rate within the European Union. Based on a model proposed by De Gregorio et al. (Rev Int Econ 2(3):284–305, 1994a), we show that both product market regulations in nontradable sectors and employment protection tend to raise the real exchange rate. We then carry out an econometric estimation for European countries for 1985–2006 to quantify the contributions of the pure Balassa–Samuelson effect and those of market regulations on real exchange-rate variations. Based on this evidence and on a counter-factual experiment, we conclude that the relative evolutions of product market regulations and employment protection across countries play a very significant role for real exchange-rate variations within the European Union and especially within the euro area, through their impacts on the relative price of nontradable goods.     

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.     

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.     

Export behavior of German SMEs in the Eurozone

The paper investigates the export behavior of German small and medium-sized enterprises (SMEs) in response to the introduction of Euro and the subsequent fall in trade costs. Based on a testable prediction derived from Helpman et al. (American Economic Review 94:300–316, 2004) and Helpman (Journal of Economic Literature 44:589–630, 2006), the paper argues that the likelihood of SMEs to become an exporter increases after the monetary union. By using an empirical probit estimation technique, it is found that SMEs, and especially medium-sized enterprises, indeed benefit from cost reductions in entering into export markets. What is more, firms operating in furniture, electrical equipment, plastics, medical instruments, machinery and textiles are more likely to benefit from monetary union. These results are robust to using exchange rate volatility as a proxy for the cost reductions due to monetary union.     

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.     

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.     

Restrictive immigration policy in Germany: pains and gains foregone?

Many European countries restrict immigration from new EU member countries. The rationale is to avoid adverse wage and employment effects. We quantify these effects for Germany. Following Borjas (in Q J Econ CXVIII(4):1335–1374, 2003), we estimate a structural model of labor demand, based on elasticities of substitution between workers with different experience levels and education. We allow for unemployment which we model in a price-wage-setting framework. Simulating a counterfactual scenario without restrictions for migration from new EU members countries in Germany, we find moderate negative wage and employment effects for incumbent foreigners, but positive effects for natives. Our results indicate that for the native German population as a whole the immigration restrictions are not welfare enhancing.     

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.     

FX intervention in the Yen-US dollar market: a coordination channel perspective

The coordination channel has recently been established as an additional means by which foreign exchange market intervention may be effective. It is conjectured that strong and persistent misalignments of the exchange rate are caused by a coordination failure among fundamentals-based traders. In such situations official intervention may act as a coordinating signal, encouraging traders to engage in stabilizing speculation. We apply the framework developed in Reitz and Taylor (Eur Econ Rev 52(1), 55?C76 2008) to daily data on the yen-US dollar exchange rate and on Federal Reserve and Japanese Ministry of Finance intervention operations. The results provide further support for the coordination channel of intervention effectiveness.     

Explaining rising regionalism and failing multilateralism: consensus decision-making and expanding WTO membership

The beleaguered progress of the Doha Development Agenda of the World Trade Organisation (WTO) presents something of a puzzle for economic theory: if multilateralism is an effective forum for liberalisation (as it has been in the past), then why have the current round of talks faltered amid the proliferation of preferential trade agreements (PTAs)? This paper builds a ‘hub and spoke’ version of the Maggi (Am Econ Rev 89(1):190–213, 1999) model of trade negotiations to shows that the combination of the WTO single-undertaking and consensus decision-making principles with an expanded and more diverse membership can render multilateralism less desirable for hub countries than bilateralism. It is argued that these principles give spoke countries de facto veto power meaning that their threat point during WTO negotiations is a reversion to PTA negotiations between all parties. Accordingly, spoke countries with relatively less to gain from the WTO can use their veto power to extract gains from those that would benefit substantially. If an expanding WTO membership has increased the number of such countries, then the benefits of multilateralism versus regionalism from the perspective of hub counties may have been diminished to such an extent that they are no longer willing to wait for the conclusion of the Doha round before engaging in PTA negotiations.     

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.     

EU Enlargement and the New Goods Margin in Austrian Trade

Using the methodology developed in Kehoe and Ruhl (J Polit Econ 121(2):358–392, 2013), I measure the change in the extensive, or new goods, margin of trade between Austria and the ten new entrants to the European Union in 2004. On average, the new goods account for 56 % of the bilateral trade flow after enlargement. A time series measure shows growth in the new goods margin coincides with the period surrounding the 2004 enlargement, which provides evidence on the importance of the role played by the new goods margin in the growth in trade during a trade liberalization.     

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.     

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)      

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.     

Real Exchange Rates,the Trade Balance and Net Foreign Assets: Long-Run Relationships and Measures of Misalignment

In this paper we estimate equilibrium exchange rates for 23 OECD countries and four less mature economies in a panel data setting. Our empirical analysis demonstrates significant links between the trade balance and net foreign assets, and between real exchange rates and the trade balance, rather than between real exchange rates and net foreign asset, as predicted by the model of Lane and Milessi-Ferretti (2002). Our study indicates that, in terms of the association between real exchange rates and trade balance, there is heterogeneity between the emerging market economies and the OECD countries. Finally, we construct various measures of exchange rate misalignment for all the exchange rates included in our panels.
