Within-groups wage inequality and schooling: further evidence for Portugal

This article provides further evidence on the positive impact of schooling on within-groups wage dispersion in Portugal, using data on male workers from the 2001 wave of the European Community Household Panel. The issue of schooling endogeneity is taken into account by using the latest available instrumental-variable technique for quantile regression, i.e. the control-function estimator due to Lee (2007 Lee, S. 2007. Endogeneity in quantile regresssion models: a control function approach. Journal of Econometrics, 141: 1131–58. [Crossref], [Web of Science ®] , [Google Scholar]). The findings are compared with earlier results based on different techniques, i.e. the instrumental-variable estimator due to Arias et al. (2001 Arias, O, Hallock, KF and Sosa-Escudero, W. 2001. Individual heterogeneity in the returns to schooling: instrumental variables quantile regression using twins data. Empirical Economics, 26: 7–40. [Crossref] , [Google Scholar]) and the standard exogeneity-based estimator due to Koenker and Bassett (1978 Koenker, R and Bassett, G. 1978. Regression quantiles. Econometrica, 46: 33–50. [Crossref], [Web of Science ®] , [Google Scholar]).     

Will the skill-premium in the Netherlands rise in the next decades?

While the skill-premium has been rising sharply in the US and the UK for 20 years, the Dutch skill-premium decreased for much of that period and only started to rise in the early 90s. In this article, we investigate whether the Dutch skill-premium will rise in the next decades. To answer this question, we forecast the skill-premium using the Katz and Murphy (1992 Katz, L and Murphy, K. 1992. Changes in relative wages, 1963–1987: supply and demand factors. Quarterly Journal of Economics, 107: 35–78. [Crossref], [Web of Science ®] , [Google Scholar]) and the Krusell et al. (2000 Krusell, P, Ohanian, L, Ríos-Rull, J-V and Violante, G. 2000. Capital-skill complementarity and inequality: a macroeconomic analysis. Econometrica, 68: 1029–53. [Crossref], [Web of Science ®] , [Google Scholar]) models. The Katz and Murphy model (KM) explains demand shifts by skill-biased technological change in unobservable variables captured by a time trend. In contrast, the Krusell et al. model (KORV) explains demand shifts by (observable) changes in the capital stock under a capital-skill complementarity technology. The results show that while the KM model predicts that the skill-premium will have increased by 30% in 2020, based on realistic predictions of the stock of capital, the KORV model predicts that the skill-premium will remain between ?5 and +5% of its 1996 level.     

Salaried employment and earnings in Indonesia: new evidence on the selection bias

This article uses household survey data to estimate the determinants of earnings in Indonesia, a country where nonsalaried work is widespread and earnings data are available for salaried employees only. We deal with the selection bias by estimating a Full-Information Maximum Likelihood (FIML) system of equations, where selection into the labour market is modelled in a multinomial setting. We find that some estimated parameters of the earnings equation differ from a binomial selection procedure by Heckman (1979 Heckman, J. 1979. Sample selection bias as a specification error. Econometrica, 47: 153–61. [Crossref], [Web of Science ®] , [Google Scholar]), in particular for those variables with the strongest impact on the selection into the different labour-market statuses. However, the estimated returns to education are unaffected, even when we deal with the endogeneity of educational attainment following Duflo (2001 Duflo, E. 2001. Schooling and labour market consequences of school construction in Indonesia: evidence from an unusual policy experiment. American Economic Review, 91: 795–813. [Crossref], [Web of Science ®] , [Google Scholar]). Overall, our findings show that the choice of the selection rule affects the estimates of the earnings determinants in the Indonesian labour market.     

Economic class and the distribution of income: a time-series analysis of the UK economy, 1955–2010

This paper contributes to our understanding of the determinants and dynamics of surplus-value using quarterly UK data, 1955–2010, and the Johansen (1988 Johansen, S. 1988. Statistical analysis of cointegrated vectors. Journal of Economic Dynamic and Control, 12: 231–54. [Crossref], [Web of Science ®] , [Google Scholar], 1991 Johansen, S. 1991. Estimation and hypothesis of cointegration vectors in Gaussian vector autoregressive models. Econometrica, 59: 1551–80. [Crossref], [Web of Science ®] , [Google Scholar]) cointegration and vector error correction model (VECM). A model is introduced to define this Marxian concept, before we explain distribution, paying attention to three forces that are traditionally seen as drivers of power in this struggle: (i) working class militancy; (ii) the size of the ‘reserve army’ of the unemployed; and (iii) political party. Our results demonstrate the ongoing relevance of Marxian economics in providing an alternative, robust and significant explanation of distribution in the post-war UK economy.     

Estimating persistence in Canadian unemployment: evidence from a Bayesian ARFIMA

The degree of persistence in aggregate Canadian unemployment is estimated within a Bayesian ARFIMA class of models. The results conclude that unemployment exhibits persistence in the short and intermediate run. The evidence of persistence is stronger than previously reported by Koustas and Veloce (1996 Koustas, Z and Veloce, W. 1996. Unemployment hysteresis in Canada: an approach based on long-memory time series models. Applied Economics, 28: 823–31. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). This persistence cast a vital implication regarding disinflation policies, Based on the unemployment rate, these policies will prove very costly in terms of lost output and – if implemented – they considerably lengthen recessions.     

Estimation of SEs for heteroscedastic and cross-sectionally correlated data

This study develops SE estimators for heteroscedastic and cross-sectionally correlated data. The new estimators are a cross-sectional version of the White and Domowitz (1984 White, H and Domowitz, I. 1984. Nonlinear regression with dependent observations. Econometrica, 52: 143–61. [Crossref], [Web of Science ®] , [Google Scholar]) and Newey and West (1987 Newey, W and West, K. 1987. A simple positive semi-definite, heteroscedasticity and autocorrelation consistent covariance matrix. Econometrica, 55: 703–8. [Crossref], [Web of Science ®] , [Google Scholar]) estimators, and therefore, consistent in the presence of heteroscedasticity and cross correlation of unknown form. Unlike the estimators in the literature, these estimators can control for cross correlation even for single-period cross-sectional data.     

Institutions and growth: evidence from estimation methods robust to weak instruments

This article focuses on the empirical approach proposed by Hall and Jones (1999 Hall, RE and Jones, CI(HJ99). 1999. Why do some countries produce so much more output per worker than others?. The Quarterly Journal of Economics, 114: 83–116. [Crossref], [Web of Science ®] , [Google Scholar]) to estimate the effect of what they call ‘social infrastructure’ on productivity across countries. We consider the issue of weak identification in their linear instrumental variables model. The evidence obtained from partially robust estimators, such as the k-class and jackknife estimators, is interpreted on the basis of Monte Carlo studies. Our findings suggest that using certain k-class estimators allows exclusive reliance on the linguistic variables to instrument for institutional quality despite their low correlation with the endogenous regressor in question.     

Explaining the Delayed Effect of Monetary Policy: The Role of Inventories and Factor-hoarding

This paper proposes a new model accounting for the delayed effect of monetary policy shocks on output. The key feature of the model is to distinguish a variety of margins (i.e., inventory adjustments, hours per worker, efforts and employments) on which firms adjust output in response to macroeconomic shock. When these multiple margins are properly introduced to an otherwise standard modern monetary business cycles model, the interplay between inventory adjustments and the one-period lag in adjusting employment can produce the hump-shaped response of output to monetary shock. Given the weak evidence on habit formation at household level found in Dynan (2000) Dynan, K. (2000). Habit formation in consumer preferences: evidence from panel data. American Economic Review, 90 (3), 391–406. doi: 10.1257/aer.90.3.391[Crossref], [Web of Science ®] , [Google Scholar] and Flavin and Nakagawa (2008) Flavin, M., &; Nakagawa, S. (2008). A model of housing in the presence of adjustment costs: a structural interpretation of habit persistence. American Economic Review, 98, 474–495. doi: 10.1257/aer.98.1.474[Crossref], [Web of Science ®] , [Google Scholar], therefore, this paper provides an alternative explanation for the delayed effect of monetary policy without relying on the habit formation.     

Insurance and rural welfare: what can panel data tell us?

Assessing the scope for insurance in rural communities usually requires a structural model of household behaviour under risk. One of the few empirical applications of such models is the study by Rosenzweig and Wolpin (1993 Rosenzweig, MR and Wolpin, K. 1993. Credit market constraints, consumption smoothing, and the accumulation of durable production assets in low-income countries: investment in bullocks in India. Journal of Political Economy, 101: 223–44. [Crossref], [Web of Science ®] , [Google Scholar]) who conclude that Indian farmers in the ICRISAT villages would not benefit from the introduction of formal weather insurance. In this article we investigate how models such as theirs can be estimated from panel data on production and assets. We show that if assets can take only a limited number of values the coefficients of the model cannot be estimated with reasonable precision. We also show that this can affect the conclusion that insurance would not be welfare improving.     

Anchoring-Adjusted Capital Asset Pricing Model

What happens when the capital asset pricing model is adjusted for the anchoring and adjustment heuristic of Tversky and Kahneman [1974 Tversky, A., and D. Kahneman. “Judgment Under Uncertainty: Heuristics and Biases.” Science, 185, (1974), pp. 1124–1131.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]]? The surprising finding is that adjusting the capital asset pricing model for anchoring provides a plausible unified framework for understanding almost all of the key asset pricing anomalies. The anomalies captured in the theoretical framework include the well-known size and value effects, high alpha of low beta stocks, accruals, low volatility anomaly, momentum effect, stock splits, and reverse stock splits. The market equity premium is also larger with anchoring. This suggests that the anchoring-adjusted capital asset pricing model may provide the needed unifying structure to behavioral finance.     

Export-led growth: are the results robust across methodologies and/or data sets? A case study of Latin America

We examine the export-led growth (ELG) hypothesis from a different perspective asking if the choice of data and/or methodology drives the results. We apply the Granger causality test modified by the corresponding error correction model using real export data from two common sources: the International Monetary Fund and the United Nations Commodity Trade Statistics. Additionally, to determine if the level of deflation could be a factor, we deflate the data at a disaggregated level and by a single export unit price index. Outcomes are compared to those obtained through the Granger causality procedure developed by Toda and Yamamoto (1995 Toda, H and Yamamoto, T. 1995. Statistical inference in vector autoregressions with possibly integrated process. Journal of Econometrics, 66: 225–50. [Crossref], [Web of Science ®] , [Google Scholar]) and Dolado and Lütkepohl (1996 Dolado, JJ and Lütkepohl, H. 1996. Making wald tests work for cointegrated VAR systems. Econometric Reviews, 15: 369–86. [Taylor &; Francis Online] , [Google Scholar]). We use sixteen Latin American countries to test our hypotheses. The analysis reveals inconsistencies in the results both by selection of data and methodology suggesting much of the debate regarding ELG, at least for Latin America, is fuelled by data and/or methodology choice, putting into question previous studies.     

Consumer decision making,E-commerce and perceived risks

This article studies how adoption and usage behaviour of the Internet and online shopping, respectively influence the preference to use electronic commerce to purchase different types of products. We empirically model the preference for electronic commerce when consumers have to buy different types of products and thus face different types of risks (Cox and Rich, 1964 Cox, D and Rich, S. 1964. Perceived risk and consumer decision making-the case of telephone survey. Journal of Marketing Research, 1: 32–9. [Crossref], [Web of Science ®] , [Google Scholar]). Unlike previous research, we find that consumers who have previously shopped online, display stronger preferences to buy products on the Internet irrespective of the perceived level of product-specific risks of online shopping. This article provides an interesting and novel insight into how both adoption and usage of electronic commerce impact on the attitude and risk perception of buying less predictable (more risky) products on the Internet.     

The Interest Rate Brake on Maturity Transformation

Must banks match asset and liability maturities, as William Barnett and Walter E. Block (2009 Barnett, William and Walter E. Block. “Time Deposits, Dimensions and Fraud.” Journal of Business Ethics 88, 4 (2009): 711–716.[Crossref], [Web of Science ®] , [Google Scholar], 2011 Barnett, William and Walter E. Block. “Rejoinder to Bagus and Howden on Borrowing Short and Lending Long.” Journal of Business Ethics 100, 2 (2011): 229–238.[Crossref], [Web of Science ®] , [Google Scholar]), as well as Ivan Jankovic (2011) Jankovic, Ivan. “Economic Calculation, Maturity Mismatching and the Credit Cycle.” New Perspectives on Political Economy 7, 1 (2011): 105–124. [Google Scholar], surmise? While we agree with these authors that issuances of fiduciary media breed financial instability, we disagree that maturity transformation represents such a case. Maturity transformation — otherwise known as borrowing short-term and lending long-term — guided by several base legal principles, does not result in the issuance of fiduciary media. Most notable among these principles is that any credit issued must be funded by borrowing of a positive duration, i.e., not via a demand deposit. We demonstrate that two factors instigate larger degrees of maturity transformation than would otherwise be the case, breeding potential instability: a continual increase in the credit supply and the provision of a lender of last resort. We also show that the interest rate is a natural stabilizing brake on the over-issuance of longer-dated credit against short-term financing.     

The persistence of Taiwan's output fluctuations: an empirical study using innovation regime-switching model

In this article we examine the persistence nature of Taiwan's aggregate output fluctuations by using the ‘innovation regime-switching’ (IRS) model in which the effect of an innovation may be permanent or transitory, depending on an unobservable state variable that follows a first order Markov chain. By applying the IRS model to Taiwan's real GDP data, we find that during the 1961 to 2000 period 61% (39%) of the real output shocks are likely to have permanent (transitory) effects. Moreover, the innovations in the officially identified expansion (contraction) are more likely to have a permanent (transitory) effect. These results are similar to those found in many studies of US real output fluctuations, e.g. Beaudry and Koop (1993 Beaudry, P and Koop, G. 1993. Do recessions permanently change output?. Journal of Monetary Economics, 31: 149–63. [Crossref], [Web of Science ®] , [Google Scholar]), Kim and Nelson (1999 Kim, C-J and Nelson, CR. 1999. Friedman's plucking model of business fluctuations: tests and estimates of permanent and transitory components. Journal of Money, Credit and Banking, 31: 317–34.  [Google Scholar]) and Kuan et al. (2005 Kuan, C-M, Huang, Y-L and Tsay, RS. 2005. An unobserved component model with switching permanent and transitory innovations. Journal of Business and Economic Statistics, 23: 443–54. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). However, we also find that Taiwan's output dynamics have changed drastically ever since year 2000. In particular, the shocks to real GDP have become more likely to have only transitory effect, even during the period of post-2001:IV expansion.     

Unit roots and purchasing power parity: another kick at the can

Lopez et al. (2005 Lopez, C, Murray, C and Papell, D. 2005. State of the art unit root tests and purchasing power parity. Journal of Money, Credit and Banking, 37: 361–9. [Crossref], [Web of Science ®] , [Google Scholar]) demonstrated that single-equation unit-root tests cannot provide conclusive evidence of whether real exchange rates are stationary because inference depends critically on the lag-lengths used to construct the test statistics, a result reinforced by a recent work by Sweeney (2006 Sweeney, D. 2006. Mean reversion in nominal G-10 exchange rates. Journal of Financial and Quantitative Analysis, 41: 685–708. [Crossref], [Web of Science ®] , [Google Scholar]). The purpose of this article is to revisit the issue, first demonstrating the necessary conditions under which this approach of testing for Purchasing Power Parity (PPP) is appropriate.     

Comparisons of robust tests for shifts in trend with an application to trend deviations of real exchange rates in the long run

We study the finite sample properties of tests for structural changes in the trend function of a time series that do not require knowledge of the degree of persistence in the noise component. The tests of interest are the quasi-Feasible Generalized Least Squares (FGLS) procedure by Perron and Yabu (2009b Perron, P and Yabu, T. 2009b. Testing for shifts in trend with an integrated or stationary noise component. Journal of Business and Economic Statistics, 27: 369–96. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) and the weighted average of the regression t-statistics by Harvey et al. (2009 Harvey, DI, Leybourne, SJ and Taylor, AMR. 2009. Simple, robust, and powerful tests of the breaking trend hypothesis. Econometric Theory, 25: 995–1029. [Crossref], [Web of Science ®] , [Google Scholar]), both of which have the same limit distribution whether the noise component is stationary or has a unit-root. We analyse the finite sample size and power properties of these tests under a variety of Data-Generating Processes (DGPs). The results show that the Perron–Yabu test has greater power overall. With respect to the size, the Harvey–Leybourne–Taylor test exhibits larger size distortions unless a moving-average component is present. Using the Perron and Yabu procedure to test for structural changes in the trend function of long-run real exchange rates with respect to the US dollar indicates that for 17 out of 19 countries, the series have experienced a shift in trend since the late nineteenth century.     

The Kyoto Protocol,market power,and enforcement

The Kyoto Protocol aims to limit aggregate carbon emissions by participating countries to 1990 emissions levels in aggregate. It also allows for the creation of a permit market in which countries will be able to buy and sell the right to emit carbon dioxide. This paper investigates how market power, held by the countries of the former Soviet Union, and enforcement of the carbon emission limits might affect the abatement and the cost of compliance with the Kyoto Protocol. To do so, it uses a modified version of the van Egteren–Weber (1996 Van Egteren, H and Weber, M. 1996. Marketable permits, market power, and cheating. Journal of Environmental Economics and Management, 30: 161–74. [Crossref], [Web of Science ®] , [Google Scholar]) model to investigate a permit market in the presence of both market power and enforcement difficulties. It then simulates the model, finding that if meeting abatement targets is the goal, regulating the supply side of the market and convex fine schedules are the most effective tools.     

Two Sides of the Same Coin: Re-examining Nepotism and Discrimination in a Segmented Society

Abstract

We report the results from a series of trust games designed to distinguish racial discrimination from racial nepotism, played with a sample of high school students in Cape Town, South Africa. In contrast to the original work in this regard by Fershtman et al. (2005 Fershtman, C., Gneezy, U. and Verboven, F. 2005. “Discrimination and Nepotism: the efficiency of the anonymity rule,”. Journal of Legal Studies, 34: 371–396. [Crossref], [Web of Science ®] , [Google Scholar]), we find considerably greater heterogeneity in the way that proposers respond to the revealed racial identity of their partner, with nepotism being a dominant behavior. However, while some proposers exhibit a nepotistic bias in their offers that favors in-group members on average, others exhibit a nepotistic strategy that favors out-group members. A consequence of this nepotism is that both efficiency and equity are reduced on average.     

Immiserizing Growth and the Metzler Paradox in the Ricardian Model

Conditions for the occurrence of immiserizing growth and the Metzler paradox are analysed in the Ricardian model when consumers in the foreign country have Leontief preferences while consumers in the home country have Cobb-Douglas preferences. By using specific functional forms, the conditions for the occurrence of the two paradoxes are defined in terms of the exogenous parameters of the model rather than endogenous variables such as the foreign import demand elasticity in the conditions of Bhagwati (1958) Bhagwati, J. N. 1958. Immiserizing growth: a geometrical note. Review of Economic Studies, 25: 201–205. [Crossref], [Web of Science ®] , [Google Scholar] and Metzler (1949a Metzler, L. A. 1949a. Tariffs, the terms of trade and the distribution of national income. Journal of Political Economy, 57: 1–29. [Crossref], [Web of Science ®] , [Google Scholar], b Metzler, L. A. 1949b. Tariffs, international demand, and domestic prices. Journal of Political Economy, 57: 345–351. [Crossref], [Web of Science ®] , [Google Scholar]). It is shown that the simultaneous occurrence of both paradoxical results is possible for some parameter values.     

Linear and nonlinear Granger-causality between short-term and long-term interest rates during business cycles

This paper is about the causal relationship between short-term and long-term interest rates in the US and Canada. To that end, we apply a linear Granger causality test introduced by Toda and Yamamoto (1995 Toda, H. Y., and T. Yamamoto. 1995. “Statistical Inference in Vector Autoregressions with Possibly Integrated Processes.” Journal of Econometrics 66 (1–2): 225–250. doi:10.1016/0304-4076(94)01616-8.[Crossref], [Web of Science ®] , [Google Scholar]) and the nonlinear Granger causality test of Diks and Panchenko (2006 Diks, C., and V. Panchenko. 2006. “A New Statistic and Practical Guidelines for Nonparametric Granger Causality Testing.” Journal of Economic Dynamics and Control 30 (9–10): 1647–1669. doi:10.1016/j.jedc.2005.08.008.[Crossref], [Web of Science ®] , [Google Scholar]). By combining linear causality effects with the nonlinear ones, it is seen that the most common Granger causality direction between short-term and long-term interest rates is a bidirectional one. We also find that nonlinear Granger causality can be found where no linear causality had been uncovered. Moreover, our findings show that during recent business cycles, the federal funds rate (in the US) and the overnight rate (in Canada) still Granger-cause long-term interest rates significantly.
