An approach recently developed by Fama and French (2000 Fama, EF and French, KR. 2000. Forecasting profitability and earnings. The Journal of Business, 73: 16175.  ) is applied to the study of whether UK company profitability is mean-reverting. A sample of roughly 987 firms per year for a period from 1982–2000 is used, drawn from Datastream. In a simple partial adjustment model convergence towards the mean at a rate of about 25% per year is found. The results are very similar in direction to those of Fama and French (2000 Fama, EF and French, KR. 2000. Forecasting profitability and earnings. The Journal of Business, 73: 16175.  ) but the results do not display significant non-linearities. The change in profitability appears to be more strongly influenced by dividends in the UK.  相似文献

This article addresses the differences in margins across exporting and nonexporting firms. We jointly estimate a translog cost function, a variable factor share equation and price-cost margin equations to analyse the effect of persistence in export activity on margins. Results indicate that nonexporters have smaller margins than persistent exporters and firms that entered foreign markets during the nineties. However, larger export ratio is negatively associated with margins for persistent exporters. It suggests that efficiency advantages for exporters are partially compensated by higher competitive pressure in international markets. These results are in accordance with the predictions of Melitz and Ottaviano (2005 Melitz, MJ and Ottaviano, GIP. 2005. Market size trade, and productivity, NBER Working Paper Series No. 11393 (forthcoming in The Review of Economic Studies) [Google Scholar]).  相似文献

This paper introduces service innovation in the proximity-concentration trade-off model of trade and foreign direct investments (FDI) [Helpman, E., M. Melitz, and S. R. Yeaple 2004 Helpman, E., M. Melitz, and S. R. Yeaple. 2004. “Export Versus FDI with Heterogeneous Firms.” American Economic Review 94 (1): 300316. doi: 10.1257/000282804322970814[Crossref], [Web of Science ®] [Google Scholar]. “Export Versus FDI with Heterogeneous Firms.” American Economic Review 94 (1): 300–316]. The idea is that innovation will have two main effects on service firms’ choice between exports and FDI. First, innovative firms will on average have higher productivity levels than non-innovative enterprises. Secondly, innovators will have to pay a higher relational distance cost for undertaking export activities, and they will, therefore, prefer to avoid (or reduce) these costs by choosing an FDI strategy instead. We test the empirical relevance of this idea on a new survey data set for a representative sample of firms in all business service sectors in Norway. The results show that firms are more likely to choose FDI rather than export the greater their productivity level and the higher the relational distance costs they face.  相似文献

Several different approaches have been followed by researchers to test the validity of Purchasing Power Parity (PPP). Since the introduction of the unit-root tests, researchers have applied a battery of these tests to determine whether the real exchange rates are stationary. If the answer is in the affirmative, PPP is validated. While application of the standard augmented Dickey–Fuller test has not provided much support for PPP, a test that incorporates nonlinearity in the rates has. Under both tests, however, the null of nonstationary is tested against the alternative of stationarity. In this article, when we switch the null with the alternative and apply Kwiatkowski et al. (1992 Kwiatkowski, D, Phillips, PCB, Schmidt, P and Shin, Y. 1992. Testing the null hypothesis of stationarity against the alternative of a unit root. Journal of Econometrics, 54: 15978. [Crossref], [Web of Science ®] [Google Scholar]) test, we provide relatively more support for the theory, getting closer and closer towards solving the PPP puzzle.  相似文献

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: 3578. [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: 102953. [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.  相似文献

This paper aims to test whether a given type of process innovation, namely flexible production technologies (FPTs), contributes to increased firm efficiency. Using one-year firm data from the Portuguese manufacturing industry and applying a parametric stochastic frontier approach, individual technical efficiencies are obtained and their determinants simultaneously estimated, using a single-step procedure recently proposed by Battese and Coelli (1995 Battese, G and Coelli, T. 1995. A model for technical inefficiency effects in a stochastic frontier production function and panel data. Empirical Economics, 20: 32532.  ). The results support the hypothesis that technological flexibility, measured through the use of FPTs, is important in explaining differences in efficiency. Furthermore, given the specifications of the stochastic frontier function, the null hypothesis that Portuguese firms are fully technically efficient is rejected.  相似文献

The paper investigates market share instability in the context of Brazilian industry for the 1986–1998 period. The paper proposes the use of panel data unit root tests to access market share instability for a sample of industrial firms from different sectors and therefore generalizes related time series unit root tests proposed by Gallet and List (2001 Gallet, CA and List, JA. 2001. Market share instability: an application of unit root tests for the cigarette industry. Journal of Economics and Business, 53: 47380.  ). The results mostly indicate that one cannot reject the hypothesis of market share instability and therefore there exist some degree of market rivalry in the Brazilian case.  相似文献

Although cigarette manufacturers were aware of the addictive properties of nicotine as early as 1962, the information did not become available to the US public until 1979 when the Surgeon General disclosed it (US Department of Health, Education, and Welfare, 1979 US Department of Health, Education, and Welfare 1979 Smoking and Health: A Report of the Surgeon General, Public Health Services, Office of Smoking and Health Washington ). This study simulates the impact this information would have had on the demand for cigarettes had it been released in 1962. The simulations build on past work by Fenn et al. (2001 Fenn, A, Antonovitz, F and Schroeter, J. 2001. Cigarettes and addiction information: new evidence in support of the rational addiction model. Economics Letters, 72: 345.  ) who found evidence that the release of addiction information resulted in a structural shift in demand in 1979. In the present study, the econometric results from Fenn et al. (2001 Fenn, A, Antonovitz, F and Schroeter, J. 2001. Cigarettes and addiction information: new evidence in support of the rational addiction model. Economics Letters, 72: 345.  ) are used to compute simulated time paths for state-level per capita consumption under the hypothetical scenario involving the earlier release of the addiction information. Using these simulated consumption paths; the projected reductions in cigarette sales revenue are calculated. These dollar figures provide a benchmark against which to judge the compensation amounts that the industry must pay because of recent tobacco lawsuit settlements.  相似文献

This article develops an econometric model in order to study country risk behaviour for six emerging economies (Argentina, Mexico, Russia, Thailand, Korea and Indonesia), by expanding the country beta risk model of Harvey and Zhou (1993 Harvey, CR and Zhou, G. 1993. International asset pricing with alternative distributional specifications. Journal of Empirical Finance, 1: 10731. [Crossref] [Google Scholar]), Erb et al . (1996a, b) and Gangemi et al . (2000). Towards this end, we have analysed the impact of macroeconomic variables, especially monetary policy, upon country risk, by way of a time-varying parameter approach. The results indicate an unstable effect of monetary policy upon country risk in periods of crisis. However, this effect is stable in other periods, and the Favero–Giavazzi effect is not verified for all economies, with an opposite effect being observed in many cases.  相似文献

Economic theory is paying increasing attention to a non-observed economy (NOE) and its causes. Recently, a couple of works (Rosser et al., 2000 Rosser, J. B., Rosser, M. V. and Ahmed, E. 2000. Income inequality and the informal economy in transitions economies. Journal of Comparative Economics, 28(1): 156171.  [Google Scholar], 2003 Rosser, J. B., Rosser, M. V. and Ahmed, E. 2003. Multiple unofficial economy equilibria and income distribution dynamics in systemic transition. Journal of Post Keynesian Economics, 25(3): 425447. [Web of Science ®] [Google Scholar]) have claimed that there is a positive relationship between income inequality and the size of NOE. This supposed relationship is not so clear and deserves in-depth analysis. There is a crucial aspect that has been completely avoided in these studies: income inequality is mainly measured using ‘regular’ incomes and this fact could lead to some bias. The existence of a certain size of NOE implies some income evasion that can affect the inequality indexes used in the study of the relationship between NOE and inequality. Including the regional share of NOE in a wage equation, I find that, in the specific case of the Italian private sector employees, the income evasion attached to NOE tends to reduce inequality measured by regular wages statistics.  相似文献

In their seminal work, Im et al. (1997 Im, KS, Pesaran, MH and Shin, Y. 1997. Testing for unit roots in heterogeneous panels. 1997. Working paper, Department of Applied Economics, University of Cambridge. Mimeographed [Google Scholar], 2003 Im, KS, Pesaran, MH and Shin, Y. 2003. Testing for unit roots in heterogeneous panels. Journal of Econometrics, 115: 5374. [Crossref], [Web of Science ®] [Google Scholar]) suggested that time series for several cross-sectional units could be used to increase the power of the Dickey--Fuller unit root test. They argued that when cross-sectional correlation is a problem that can be modelled by a time-specific factor, demeaning across the cross-sectional units can solve the problem. In this study, this proposition is proven valid, but it is also shown that previously supplied standardizing moments are inappropriate when the number of cross-sections are small, causing size to differ from the significance level. To correct this size distortion, the current paper supplies response surface parameters that can be used to obtain moments that are valid when a time-specific factor suffices for modelling cross-sectional correlation in the heterogeneous panel data unit root framework. The correct size of the panel data unit root test comes at the cost of a somewhat lower power against a stationary alternative.  相似文献

This study concentrates on four computerized political markets in Germany between 1990 and 1998. While this new method for the prediction of election events worked quite well in the USA it did not perform as well in Germany. Searching for the causes of this distinction it is shown that, in contrast to the findings of Forsythe et al. (1992 Forsythe, R, Nelson, F, Neumann, GR and Wright, J. 1992. Anatomy of an experimental political stock market. American Economic Review, 82: 114261.  ), (i) extraordinary profits were achieved less by people who took advantage of other people's anomalies than by those people who acquired an advantage from the existence of asymmetric information, (ii) the marginal trader hypothesis does not hold when applied to German markets, and that (iii) traders relied on public opinion polls. It is argued that these distinctions are caused by the differences in the German and the US voting systems. Additionally, it is shown that to a certain extent (iv) election markets were able to predict the contemporary mood of the electorate without the help of public opinion polls, (v) first of all the informed traders used public opinion polls as a source of information, and (vi) prices themselves became a source of information on which expectations were based.  相似文献

The development of accounting, auditing and capital markets in China were an integral component of China's economic reforms; auditing was regarded as being critically important to achieving the desired policy objective of delivering a market economy (Yang and Yang, 1998 Yang, J. W. and Yang, J. 1998. The Handbook of Chinese Accounting (in Chinese), Hong Kong: Oxford University Press.  [Google Scholar]). This article examines the quasi-qualification hypothesis and tests whether investors valued the introduction of Special Treatment (ST) status for firms in 1998. Our empirical analysis fails to find significant support for the quasi-qualification hypothesis. In contrast, it appears that the issuance of ST status was valued by investors; the issuance of ST status led investors to discriminate between firms.  相似文献

The central aim of this paper is to investigate whether shocks to Fiji's tourism industry have a permanent effect or a transitory effect on tourist expenditure in Fiji. To accomplish this aim the Zivot and Andrews (1992 Zivot, E and Andrews, D. 1992. Further evidence of the great crash, the oil-price shock and the unit-root hypothesis. Journal of Business and Economic Statistics, 10: 25170.  ) one break test and the Lumsdaine and Papell (1997 Lumsdaine, R and Papell, D. 1997. Multiple trend breaks and the unit root hypothesis. Review of Economics and Statistics, 79: 21218.  ) two break tests are used. The one break and two break tests reveal 1987 – the year of the military coups in Fiji – as the year of the break. Moreover, it is possible to reject the unit root null leading to the conclusion that shocks to Fiji's tourism industry have a transitory effect on tourist expenditure in Fiji.  相似文献

Many applied economists face problems in selecting an appropriate technique to estimate short and long-run relationships with the time series methods. This article reviews three alternative approaches viz., general to specific, vector autoregressions and the vector error correction models. As in other methodological controversies, definite answers are difficult. It is suggested that if these techniques are seen as tools to summarize data, as in Smith (2000 Smith, RP. 2000. “Unit Roots and all that: the impact of time-series methods on macroeconomics”. In Macroeconomics and the Real World, Edited by: Backhouse, RE. and Salanti, A. 199215. Oxford: Oxford University Press.  [Google Scholar]), often there maybe only minor differences in their estimates. Therefore a computationally attractive technique is likely to be popular.  相似文献

In this article, the authors use the concept of the hierarchy of money found in the works of Minsky (2008 Minsky, H. [1986]2008. Stabilizing an Unstable Economy. New Haven, CT: Yale University Press. [Google Scholar][1986]), Foley (1987 Foley, D. 1987. “Money in Economic Activity.” In The New Palgrave: Money, edited by J. Eatwell, M. Milgate, and P. Newman, 519525. New York, NY: W.W. Norton.[Crossref] [Google Scholar]), Wray (1990 Wray, L. R. 1990. Money and Credit in Capitalist Economies: The Endogenous Money Approach. Aldershot, UK: Edward Elgar. [Google Scholar]), and Bell (2001 Bell, S. 2001. “The Role of the State and the Hierarchy of Money.” Cambridge Journal of Economics 25 (2):14963.[Crossref], [Web of Science ®] [Google Scholar]) to analyze the process of liquidity creation in modern capitalist economies where shadow banks play an active role. They abandon the narrow focus on banks as the creators of money as well as the idea that nonbank financial institutions are mere intermediaries between savers and borrowers. Instead, the authors demonstrate that, similar to banks, nonbank financial institutions and foreign banks (through their cross-border activities) create liquidity endogenously by leveraging over the liabilities of entities hierarchically above them. The authors further elucidate Kregel’s concept of “fictitious” liquidity in the context of the hierarchy of financial liabilities, distinguishing it from “true” liquidity. By bringing shadow banks and the euro-currency markets into to the pyramid of financial liabilities, they develop a more complete framework of liquidity creation in modern capitalist economies. Their “extended” pyramid is useful for analyzing not only the fragility that may arise from the interactions between firms, households and banks, but also that which may originate through the interactions between banks, shadow banks and foreign banks.  相似文献

This builds upon the conceptual framework of Lewis-Beck and Rice (American Journal of Political Science, 27, 548–56, 1983), in combination with the empirical design of Kjar and Laband (Public Choice, 112, 143–50, 2002), to investigate home grown-ness in US presidential elections from 1972–2000. It found that, ceteris paribus, home state vote shares for US Presidential election winners are 5.19–15.11 percentage points higher due to the home grown-ness effect. In the eight presidential elections analysed, this study confirms two aspects of prior work. First, the estimate of a home grown-ness effect in presidential elections of 5.19 percentage points (on average), supports the 4 percentage point average found by Lewis-Beck and Rice (1983 Lewis-Beck, MS and Rice, TW. 1983. Localism in presidential elections: the home state advantage. American Journal of Political Science, 27: 54856.  ). Second, that support for the winning president monotonically increases as moves are made away from the opponent's home territory confirms the cascading dummy variable series approach developed by Kjar and Laband (2002 Kjar, SA and Laband, DN. 2002. On ‘home grown-ness’ in politics: evidence from the 1998 election for Alabama's Third Congressional district. Public Choice, 112: 14350.  ).  相似文献

Employing disaggregated real exchange rates from nine European counties in 16 goods categories, we assess in this study the nonlinearity in the real exchange rates. Surprisingly, we find evidence for nonlinearity in only four (10) out of 143 series with the linearity test proposed by Harvey et al. (2008 Harvey, D. I., Leybourne, S. J. and Xiao, B. 2008. A powerful test for linearity when the order of integration is unknown. Studies in Nonlinear Dynamics and Econometrics, 12 Art 8[Web of Science ®] [Google Scholar]) at the 5% (10%) significance level. This result differs greatly from those of Juvenal and Taylor (2008 Juvenal, L. and Taylor, M. P. 2008. Threshold adjustment of deviations from the law of one price. Studies in Nonlinear Dynamics and Econometrics, 12 Art 8[Web of Science ®] [Google Scholar]), Imbs et al. (2003 Imbs, J., Mumtaz, H., Raven, M. O. and Rey, H. 2003. Nonlinearities and real exchange rate dynamics. Journal of the European Economic Association, 1: 63949. [Crossref] [Google Scholar]), Sarno et al. (2004 Sarno, L., Taylor, M. P. and Chowdhury, I. 2004. Nonlinear dynamics in deviations from the law of one price: a broad-based empirical study. Journal of International Money and Finance, 23: 125. [Crossref], [Web of Science ®] [Google Scholar]) and Berka (2009 Berka, M. 2009. “Non-linear adjustment in law of one price deviations and physical characteristic of good”. In Review of International Economics Vol. 17, 5173.  [Google Scholar]), who report ample evidence for nonlinearity for the same or similarly disaggregated real exchange rate datasets.  相似文献

This article is devoted to the evaluation of the institutional matrices theory (IMT), which was designed to illustrate the differences between Russian and Western political economic systems. IMT has no matrix, and it is an ideological declaration rather than a theory. It is a set of assertions and assumptions that are adopted without evidence, and then hypostatized to be Russian and Western socioeconomic systems. IMT literature claims to utilize the reciprocity, redistribution, and exchange model of Karl Polanyi (1944 Polanyi, Karl. The Great Transformation. New York, NY: Rinehart &; Company, 1944. [Google Scholar], 1957 Polanyi, Karl. “The Economy as Instituted Process.” In Trade and Market in the Early Empires: Economies in History and Theory, edited by Karl Polanyi, Conrad M. Arensberg and Harry W. Pearson, pp. 239-270. New York, NY: Free Press, 1957. [Google Scholar]). However, IMT suffers from a number of assumptive and methodological problems in its application, the first of which consists of the complete exclusion of reciprocity from consideration. The first section of the article is an explanation of problems with IMT, and the second section demonstrates some particulars of the IMT problems with a real-world social fabric matrix from a Western nation.  相似文献

Emerging countries around the world have been growing fast over the last thirty years, with most of these countries basing their economic development on a state capitalism. Within these countries, there is a concentration of wealth in the hands of a few people. This fact confirms the analysis of Thorstein Veblen (1898 Veblen, Thorstein. “Why Is Economics Not an Evolutionary Sciences?Quarterly Journal of Economics 12, 2 (1898): 373397.[Crossref] [Google Scholar]) who shows the gap that exists between the vested interest of the rich and the unmet needs of the poor. The world happiness report (Helliwell, Layard and Sachs 2016 Helliwell, John F., Richard Layard and Jeffrey Sachs, eds. World Happiness Report 2016. World Happiness, 2016. Available at http://worldhappiness.report/wp-content/uploads/sites/2/2016/03/HR-V1_web.pdf. Accessed December 1, 2016. [Google Scholar]) also shows for the emerging economies a gap between the world rank in economic growth and in wellbeing. I propose a new paradigm of development for two emerging economies, Brazil and South Africa, by putting human development in the center of economic development and by using different approaches in economics and psychology. My analysis links the theories of Carl Shapiro and Joseph E. Stiglitz regarding “efficiency wages” (1984 Shapiro, Carl and Joseph E. Stiglitz. “Equilibrium Unemployment as Worker Disciplines Devices.” American Economic Review 74, 3 (1984): 433444.[Web of Science ®] [Google Scholar]) with the complexity approach (Le Moigne 1995 Le Moigne, Jean-Louis. La modélisation des systèmes complexes. Paris, France: Dunod, 1995. [Google Scholar]). This approach combines the results of positive psychology (Kahneman 2011 Kahneman, Daniel. Thinking, Fast and Slow. London, UK: Penguin, 2011. [Google Scholar]) with the role of local institutions for improving the economic development of emerging economies (Deaton 2016 Deaton, Angus. La grande évasion: Santé, richesse et origine des inégalités. Paris, France: PUF, [2015] 2016. [Google Scholar]). In the first section of the article, I examine definitions of economic and human wealth. In the second section, I analyze the gaps that exist between the standard-of-living ranking and the wellbeing ranking for both Brazil and South Africa in order to present meso-happiness indexes linking the micro- and macro-levels of human wealth. In the last section, I analyze the way local institutions in Brazil and South Africa could create dynamic links for these countries’ efficient functioning in the world economy.  相似文献
