Market access for sale

This paper focuses on the links between foreign lobbying and preferential market access granted by the United States' government to exporters in the rest of the Americas. We first develop a simple framework based on Grossman and Helpman [Grossman, G., Helpman, E., 1994. Protection for sale. American Economic Review 84 (4) 833–850.] to explain how lobbying by foreign firms affects their preferential access to the United States market. We then estimate the model using data on tariff preferences and lobby contributions for the 34 countries in the region. Empirical results suggest that foreign lobbying is an important force behind preferential market access to the United States. The structural estimates indicate that the weight given to foreign lobby contributions in the United States' government objective function is five times higher than the weight granted to tariff revenue forgone due to preferences. Thus, our results indicate that market access is up for sale and foreign lobbies are buying it.     

Strategic policies and growth: an applied model of R&D-driven endogenous growth

We introduce and explore a general equilibrium model with R&D-driven endogenous growth, whose antecedents are the models of Romer (1990) [Romer, P.M., 1990. Endogenous technological change. Journal of Political Economy, 98, S71-102] and Grossman and Helpman (1991) [Grossman, G.M., Helpman E., 1991. Innovation and Growth in the Global Economy, The MIT Press, Cambridge]. Utilizing evidence from recent econometric studies on sources of growth, the model also accounts explicitly for cross-border technological spillovers. The model is specified and calibrated to data from Japan, and is solved to obtain both the transitional and the steady-state equilibria. We explore the effects of selective trade and R&D promotion policies on long-run growth and social welfare. The model results suggest that while a strategic trade policy has little effect on re-allocating resources into domestic R&D activities, it can significantly affect the cross-border spillovers of technological knowledge, which, in turn, stimulates growth. We find that trade liberalization may cause the growth rate to fall and lead to a loss of social welfare in the long-run, although it improves welfare in the short-run. R&D promotion policies stimulate growth by inducing private agents to allocate more resources to domestic R&D, as well as to take greater advantage of global R&D spillovers. Here, we find significantly high growth effects together with sizable gains in social welfare at low incidence to tax payers.     

The export price index with the effect of variety and an empirical analysis

The standard international trade models predict that economic growth induces decreasing export prices. Korea has recorded sustainable economic and export growth, and its export prices have been deteriorating over the last decades. Unlike the standard assumption of one good per country, the new theoretical approach by Krugman [Krugman, P. (1980) ‘Scale Economies, Product Differentiation, and Pattern of Trade’. American Economic Review 70, 950–959, Krugman, P. (1989) ‘Differences in income elasticities and trends in real exchange rates’. European Economic Review, 33, 1055–1085.], and Helpman and Krugman [Helpman, E. and Krugman, P. (1985), Market structure and foreign trade: increasing returns, imperfect competition, and international economy, The MIT Press, Cambridge, MA.] takes into account varieties of goods produced in each country. And many studies suggest that traditional estimates without variety effect have been rather under-stated. Therefore this paper develops a proper modeling for quantifying the impact of export variety on an exact export price index. Throughout the period (1984–2000), the conventional export price index without variety effect leads to under-state Korea's export price by 89.3%. This paper shows that the fall in Korean export prices has been offset by the effect of export variety. This paper emphasizes the effect of export variety on international trade.     

Protection for sale or surge protection?

This paper asks whether the results obtained from using the standard approach to testing the influential Grossman and Helpman “protection for sale” model of political economy might arise from a simpler setting. A model of imports and quotas with protection occurring in response to import surges, but only for organized industries, is simulated and shown to provide parameter estimates consistent with the protection for sale framework. This suggests that the standard approach may be less of a test than previously thought.     

Evaluating growth cycle synchronisation in the EU

This paper provides an insight into the level of economic and monetary integration in Europe by analysing the degree of growth cycle synchronisation between seven European countries over the past thirty years. Two univariate trend-cycle decomposition methodologies, the Beveridge–Nelson (BN) decomposition and Harvey and Trimbur [Harvey, A.C. & Trimbur, T.M. (2003) “General Model-Based Filters for Extracting Cycles and Trends in Economic Time Series”, The Review of Economics and Statistics, 85(2), 244–255.]'s unobserved component model, together with a multivariate extension of the BN decomposition incorporating trend and cycle restrictions, are used to identify the trend and cyclical components from real GDP for each of the seven countries. The cycles extracted from the two univariate approaches vary significantly in both cycle period and amplitude. The average correlation calculated from the BN cycles are also smaller than the corresponding correlation estimated using cycles extracted from the unobserved component model. This confirms the argument in Canova [Canova, F. (1998) “Detrending and Business Cycle Facts”, Journal of Monetary Economics, 41(3), 475–512.] that the use of different trend-cycle decomposition methodologies may influence the results obtained. The results produced from the multivariate model indicate the presence of common features in the data. This may reflect the coordinated and common monetary and fiscal policies that these countries have shared over the sample period. However, the finding of codependent and heterogeneous growth cycles raises concerns about the operation of the European Monetary Union (EMU), as it implies that members may face significant stabilisation costs.     

An Analysis of Income Distribution between the North and the South: the Grossman–Helpman and Lai Results Re‐examined*

This paper studies the effects of labor supply on relative wages in a dynamic North–South model of trade. Lai (1995 )—a generalization of the Grossman and Helpman (1991a,b , ch. 11) models—showed that the relative wage of skilled (unskilled) labor in a region is positively (negatively) related to the supply of skilled (unskilled) labor in that region. These surprising results depend crucially on the specification of the functional form of the Southern imitation activity. We will show that these results (except for the relative wage of unskilled labor in Lai) are reversed in the case where the productivity of imitation depends only on the number of products the North manufactures.     

ENDOGENOUS CYCLICAL GROWTH WITH A SIGMOIDAL DIFFUSION OF INNOVATIONS

The model we propose in this paper is an extension of the one described in Freeman et al. [Freeman, S., Hong, D. and Peled, D. (1999) Endogenous Cycles and Growth with Indivisible Technological Developments. Review of Economics Dynamics, 2, 403–432]. In our model, we incorporate the process of diffusion of major innovations and analyze macroeconomic effects on consumption, capital and aggregate output. Following Bresnahan and Trajtenberg [Bresnahan, T. and Trajtenberg, M. (1995) General Purpose Technologies: Engines of Growth?. Journal of Econometrics, 65, 83–108.], Helpman [Helpman, E. (ed.) (1998) General Purpose Technologies and Economic Growth. MIT Press] and Lipsey et al. [Lipsey, R.G., Carlaw, K. and Bekar, C. (2005) Economic Transformations: General Purpose Technologies and Long Term Economic Growth. Oxford University Press.] we assimilate major innovations with the emergence of certain GPTs, and we suggest that the diffusion process for these technologies, at a large scale, might follow an S-shaped pattern. The proposed model presents optimum stationary solutions which are cyclical and have a wave dynamic within each cycle. The cycles are characterized by certain co-movements in consumption, R&D investment, capital accumulation and output. Consideration of the innovation diffusion process highlights new aspects of endogenous cycles and long-run growth.     

Information transmission and inefficient lobbying

In a seminal paper, Grossman and Helpman (1994) introduced a framework to understand how lobbying influences the choice of import/export tariffs. In this paper we extend their analysis and assume that lobbies have private information to analyze the effects of information transmission in a Grossman and Helpman lobby game. Information transmission leads to two agency costs. One refers to the cost of signaling and the other to the cost of screening the lobby's competitiveness. The signaling cost reduces distortions resulting from the screening cost. On the other hand, distortions from the screening cost enhance the signaling cost. The two combined effects generate more distortions in the political game than each effect separately. Tariff protection and lobbies' rents are lower than those found in Grossman and Helpman's truthful equilibrium. Therefore, information transmission may improve welfare through the reduction of rent-seeking activities.     

On the Policy Implications of Endogenous Technological Progress

One of the most well-known empirical regularities in the R&D-productivity literature is the existence of substantial under-investment in R&D. This strongly suggests that government should actively promote research activities. However, the so-called 'quality-ladders' models of endogenous technological progress are inconsistent with this observation. In an extreme case, Grossman and Helpman (1991, Ch.4) suggest that R&D should always be taxed irrespective of the size of quality improvement. This paper attempts to reconcile these empirical and theoretical findings by showing that the normative results of Grossman and Helpman are not robust.     

Inequality does cause underdevelopment: Insights from a new instrument

Consistent with the provocative hypothesis of Engerman and Sokoloff [Engermann, Stanley and Kenneth Sokoloff (1997), “Factor Endowments, Institutions, and Differential Paths of Growth Among New World Economies: A View from Economic Historians of the United States,” in Stephen Haber, ed. How Latin America Fell Behind, Stanford CA: Stanford University Press., Sokoloff, Kenneth L. and Stanley L. Engerman (2000), Institutions, Factor Endowments, and Paths of Development in the New World, Journal of Economic Perspectives v14, n3, 217–32.], this paper confirms with cross-country data that agricultural endowments predict inequality and inequality predicts development. The use of agricultural endowments –specifically the abundance of land suitable for growing wheat relative to that suitable for growing sugarcane – as an instrument for inequality is this paper's approach to problems of measurement and endogeneity of inequality. The paper finds inequality also affects other development outcomes – institutions and schooling –which the literature has emphasized as mechanisms by which higher inequality lowers per capita income. It tests the inequality hypothesis for development, institutional quality and schooling against other recent hypotheses in the literature. While finding some evidence consistent with other development fundamentals, the paper finds high inequality to independently be a large and statistically significant barrier to prosperity, good quality institutions, and high schooling.     

Intergenerational Politics, Fiscal Policy and Productivity

A political–economic theory of fiscal policy is presented in which tax policy preferences are derived from a conflict of interest between individuals of different ages. Policy formation is fully rational in that an individual's beliefs regarding future policies are consistent with state-contingent policy outcomes. The overlapping generations friction that prevents the young from transacting with future members of society implies that young policymakers strategically manipulate the policy preferences of the yet unborn to lower their own expected old-age tax burden. A comparison of the original equilibrium to one induced by the “constitutional commitment” of fiscal policy isolates the strategic component of tax rates and demonstrates that aggregate labor productivity is biased as a result of the conflict.Journal of Economic LiteratureClassification Numbers: E62, H30, O40.     

Revisions to US labor market data and the public’s perception of the economy

Using the monthly “Employment Situation” reports for 1994–2013, this paper studies the revisions to US employment data. The paper shows that the first press release underestimates net job creation in expansions and overestimates it in downturns. The “errors” in reporting the data on the labor market can distort the public’s perception about the stance of the labor market and have some political consequences. This is well reflected by the finding that the job approval rating of President Obama, the index of consumer confidence, and the economic conditions index of Gallup have all been responding to the initial news on the US labor market as they were published in the Employment Situation reports.     

Extending Nash's Axioms to Nonconvex Problems

Nash's axioms are extended to a domain of nonconvex problems to characterise in a simple way the Extended Nash Bargaining Solution proposed by Conley and Wilkie (1996,Games Econ. Behav.13, 26–38). Independence of irrelevant alternatives is weakened on the new domain to take into account the possibility that the solution of the convexified problem constitutes a “relevant” alternative.Journal of Economic LiteratureClassification Number: C71, C78.     

Comment on “The endogenous aggregate elasticity of substitution for a small open economy”

This note applies the approach of Miyagiwa and Papageorgiou [Miyagiwa, K. and Papageorgiou, C., 2007. Endogenous aggregate elasticity of substitution. Journal of Economic Dynamics and Control 31, 2899–2919] to provide simple frameworks for endogenizing the aggregate elasticity of substitution between capital and labor for a growing small open economy.     

Innovation,Imitation, and Intellectual Property Rights with International Capital Movement

This paper extends the established Helpman (1993 ) model by introducing international capital movement, and obtains new results concerning the welfare implications of tightening intellectual property rights (IPR) in the South. First, if separated capital markets in the North and the South are integrated, enforcement of IPR would have more desirable welfare effects in both regions. Second, when international capital movement is allowed, the North always gains from the tightening of IPR if the imitation rate is sufficiently high. This implies that the North's demand on the South to tighten IPR becomes stronger as the integration of international capital markets progresses.     

The Political Economy of Strategic Trade Policies*

This paper applies Grossman and Helpman's (1994 ) common agency model to investigate the formation of strategic export subsidy and strategic import tariff under both Cournot competition and Bertrand competition. The results of this paper indicate that even with political pressure, the Grossman–Helpman politically‐determined export policy is identical to the rent‐shifting export policy, which is export subsidy (export tax) in Cournot (Bertrand) competition. The politically‐determined import tariff will be higher than the optimal level. This paper highlights the possibility that lobbying can restore the level of trade intervention to a more efficient one in the absence of the benevolent dictator.     

Wages,selectivity, and vacancies: Evaluating the short-term and long-term impact of the minimum wage on unemployment

Using a circular matching model (Marimon R, Zilibotti F. Unemployment vs. mismatch of talents: Reconsidering unemployment benefits. Economic Journal 1999;109; 266–291), where the wage setting is similar to Weiss (Weiss A. Job queues and layoffs in labor markets with flexible wages. Journal of Political Economy 1980; 88; 526–538), we reexamine Card and Krueger's (Card, D., Krueger, A. Myth and Measurement, the New Economics of the Minimum Wage. Princeton University Press; 1995) intuition on the impact of the minimum wage on unemployment. In the short term, a rise in the minimum wage increases the employment level by making firms less selective. In the long term, numerical simulations show that, despite the reduction of job creation, introducing a minimum wage may lower unemployment as soon as workers and jobs are sufficiently differentiated. However, beyond some limit, the wage increase raises unemployment whatever the degree of differentiation is.     

How well does a small structural model with sticky prices and wages fit postwar U.S. data?

In this paper, we ask whether a small structural model with sticky prices and wages, embedding various modelling devices designed to increase the degree of strategic complementarity between price-setters, can fit postwar U.S. data. To answer this question, we resort to a two-step empirical evaluation of our model. In a first step, we estimate the model by minimizing the distance between theoretical autocovariances of key macroeconomic variables and their VAR-based empirical counterparts. In a second step, we resort to Watson's [Watson, M.W., 1993. Measures of fit for calibrated models. Journal of Political Economy 101, 1011–1041.] procedure [Measures of fit for calibrated models. Journal of Political Economy 101 (6), 1011.1041] to quantify the model's goodness-of-fit. Our main result is that the combination of sticky prices and sticky wages is central in order to obtain a good empirical fit. Our analysis also reveals that a model with only sticky wages does not perform well according to Watson's criterion [Watson, M.W., 1993. Measures of fit for calibrated models. Journal of Political Economy 101, 1011–1041.].     

Utility Representation of an Incomplete Preference Relation

We consider the problem of representing a (possibly) incomplete preference relation by means of a vector-valued utility function. Continuous and semicontinuous representation results are reported in the case of preference relations that are, in a sense, not “too incomplete.” These results generalize some of the classical utility representation theorems of the theory of individual choice and paves the way towards developing a consumer theory that realistically allows individuals to exhibit some “indecisiveness” on occasion.

Household survey data for research on well-being and behavior in Central Asia

This paper summarizes the micro-level survey evidence from Central Asia generated and analyzed in the period 1991–2012. We provide an exhaustive overview over all accessible individual and household-level surveys undertaken in Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan – and of all academic papers published using these datasets. We argue that Central Asia is a fascinating region for the study of comparative economics given its dual experience of transition and development. However, the region is also understudied, in part due to lack of data, and especially due to a lack of panel data. We identify knowledge gaps derived from this lack of longitudinal surveys and suggest worthwhile areas for future research. Finally, we also present a new and novel individual-level panel dataset called “Life in Kyrgyzstan”.
