An appraisal of the new classical macroeconomics

This paper appraises the “new classical macroeconomics” within the framework of Lakatos's methodology of scientific research programs. In terms of its ability to predict new facts, the new classical macroeconomics program is theoretically progressive; in terms of its ability to verify some of these predictions, the program is also empirically progressive. From these considerations I conclude that the new classical macroeconomics represents a progressive scientific research program.     

Asymmetric effects of monetary policy shocks on economic performance: empirical evidence from Turkey

This study investigates the asymmetric effects of monetary policy shocks on the macroeconomic variables of exchange rate, output and inflation for an emerging economy ? Turkey ? by using monthly data between 1990 and 2014. We employ the innovative nonlinear vector autoregressive model of Kilian and Vigfusson (2011), which allows us to observe the effect of different stances (tight or loose) and different sizes (small or large) of monetary policy actions. Our empirical evidence reveals that tight monetary policy, which, in this case, is captured with a positive shock to interest rate, decreases exchange rate, output and prices, as economic theory suggests. Loose monetary policy, which is captured with a negative shock to interest rate, has the opposite effect on these variables. However, the effects of loose monetary policy are weaker than the effects of tight monetary policy because loose monetary policy shocks are less effective than tight monetary policy shocks. Moreover, as the magnitude of a shock increases, the difference between the effects of tight and loose monetary policy policies also increases.     

Corruption and economic growth: New empirical evidence

The nexus between corruption and economic growth has been examined for a long time. Many empirical studies measured corruption by the reversed Transparency International's Perception of Corruption Index (CPI) and ignored that the CPI was not comparable over time. The CPI is comparable over time since the year 2012. We employ new data for 175 countries over the period 2012–2018 and re-examine the nexus between corruption and economic growth. The cumulative long-run effect of corruption on growth is that real per capita GDP decreased by around 17% when the reversed CPI increased by one standard deviation. The effect of corruption on economic growth is especially pronounced in autocracies and transmits to growth by decreasing FDI and increasing inflation.     

Export expansion and economic growth: Further empirical evidence

This paper examines the relationship between export expansion and economic growth in a sample of seventy-three developing countries, using data for the period 1960–1978. It shows that in both groups of low- and middle-income countries, export expansion is associated with better economic performance and that an important cause of this association is the favorable impact of exports on total factor productivity. The paper also demonstrates that the effect of commodity composition of exports on the relationship between export expansion and economic growth is substantial in more advanced developing economies.     

FDI, services trade and economic growth in India: empirical evidence on causal links

This article examines the linkages between inward FDI, services trade (export and import) and economic output using co-integration and VECM causality test. These linkages have been explored both at the aggregate and at the sectoral levels (manufacturing and services). The empirical findings confirm the long-run relationship among these variables. Causality results indicate the presence of bi-directional causal relationship between FDI and economic output as well as between services exports and economic output. The results also bring out feedback relationship between services export and FDI, reconfirming the presence of complementary relationship between the two. At the sectoral level, we find at least a unidirectional causality from FDI and services exports to both manufacturing and services output and also cross-sectoral spillover effects from manufacturing output to services output and vice versa.     

Trade openness and the effectiveness of fiscal policy: some empirical evidence

Is the potency of fiscal policy lower for more open economies, as suggested by economic theory? Using annual data from the period 1951?C2007, for 62 developed and developing economies, the paper??s empirical findings show that the effectiveness of fiscal policy is indeed reduced by an economy??s trade openness, and that the effect is quantitatively substantial. In particular, the paper??s estimates suggest that an increase in trade openness by 10% of GDP reduces the magnitude of the long-run fiscal multiplier by 5?C6%.     

Exports,productivity and innovation: new firm level empirical evidence

This article examines the determinants of Portuguese exports, applying data from 277 manufacturing firms for the period 2006–2010. In 2010, these firms accounted for about 47% of total Portugal’s exports. Both the static and dynamic results of the estimated models confirm the positive influence of productivity on variations in exports. The dynamic estimations also suggest that exports in the previous period hold a positive effect on contemporaneous exports, confirming the Roberts and Tybout (1997) sunk cost hypothesis for exports. In the dynamic analysis, the labour costs and the size of the firm do not have a statistically significant effect on Portuguese exports with the findings also pointing to increased expenditure on research and development (R&D) generating no statistically significant effect on exports. The lagged R&D expenditure was also insignificant in explaining the change of Portuguese exports. Thus, these results suggest that applying a product or process innovation measure returns better results than indirect measures such as R&D expenditure.     

An agency model to explain trade credit policy and empirical evidence

This article explains trade credit policy based on the agency theory. According to this theory, we have developed an agency model based on the adverse selection and moral hazard phenomena arising from the relation between sellers and buyers. This model has been estimated by using panel data methodology applied to UK companies. Our findings strongly support the model proposed. We find that smaller firms, those with a smaller proportion of fixed assets, and those that are less profitable extend more trade credit, whereas firms with a high proportion of variable costs and high percentage of bad debts extend less.     

Exports and economic growth:some empirical evidence from the Arab Gulf countries

This paper investigates the relationship between exports and economic growth in four of the Arab Gulf countries, namely, Saudi Arabia, Kuwait, UAE, and Oman for the period 1973–93. The estimates presented indicate a positive and significant relation between the two variables. Also, the statistical adequacy of the models used is supported by the following diagnostic tests. The Bruesch-Godfrey statistic suggests the absence of serial correlation. The Farely-Hinich test fails to reject the null hypothesis that the models are structurally stable. And both the White and Hausman specification tests show that the models are correctly specified.     

Testing the exogeneity of economic time series: an application of innovation accounting

This paper proposes and presents an testable sufficient condition for testing the exogeneity of economic time series using Sims' (1980a) innovation accounting within an unconstrained vector autoregressive model. It is demonstrated that if each explanatory variable of a model is sequentially placed in the last position of the ordering of variables during orthogonalization, then strict exogeneity of the dependent variable with respect to each explanatory variable can be tested without any a priorirestrictions. The test is not biased by conditional correlations of other variables included in the model. The empirical demonstration within the VAR framework is based on a set of variables obtained by solving a macroeconomic model.     

Export orientation and domestic merger policy: theory and some empirical evidence

Abstract.  Recent 'open‐economy industrial organization' literature finds export orientation enhances the weight of post‐merger international competitive gains, favouring lenient domestic merger policy. However, mergers seldom generate the 'significant synergies' supportive of international competitive gains. Since a joint‐economies‐of‐production effect suggests domestic mergers tend to generate international competitive losses (not gains), export orientation favours strict (not lenient) domestic merger policy. We show how non‐synergistic domestic mergers in the presence of international sales might reduce national welfare and incur stringent merger reviews. A panel data set of U.S. merger policy by manufacturing sector, 1990–2001, empirically supports export orientation, leading to strict merger policy. JEL classification: L40, F10     

Optimal use of forecasts in economic policy decisions: An empirical test

A criterion for optimal use of forecasts of exogenous variables in a linear policy model with quadratic preferences is given, based on Johansen (1972). By calculating regressions of observed values with respect to raw forecast values used in the observation period, equations are established which can be used to transform raw forecasts into ‘certainty equivalents’. The method is applied to data from national budgeting and corresponding national accounts in Norway 1948–-1971. Especially the forecasts for the volume of exports, but also for import prices, could be considerably improved, for policy purposes in the context of the model of the type mentioned, by the transformation described. Some of the forecasts, when optimally transformed, should be permitted to fluctuate more strongly and thereby influence policy more strongly. Some tentative results for Sweden and the Netherlands are briefly mentioned and compared with the evidence for Norway.     

Long-run determinant of Korean economic growth: empirical evidence from manufacturing

This paper challenges the recent contrarian view that the phenomenal growth of East Asian NICs is fuelled mainly by the accumulation of production inputs not by TFP growth. To appraise this view, we investigated and re-evaluated South Korean manufacturing growth (1973(Q1)–1993(Q4)). Using Johansen's cointegrating analysis, our results show that South Korean manufacturing appears to have increasing returns to scale in production technology. The ‘learning by doing’ effect defined by Lucas (1988) is empirically supported. This effect appears to be observed as a long-run determinant of South Korean manufacturing growth. Consequently, South Korean manufacturing growth can be described by an endogenous economic growth model, such as the Lucas (1988) model, contradicting the contrarian view.     

New empirical evidence of the linkages between governance and economic output in the European Union

This paper uses data for the 27 Member States of the European Union (EU) from 2000 to 2010 to support the thesis that a positive and significant correlation exists between a nation’s quality of governance and its economic output. To achieve this goal, the elements of governance that have been reported by the Worldwide Governance Indicators project are considered. Four individual indicators for the quality of policies and institutions and a global indicator of governance quality are constructed. We estimate that, for our database, a standard deviation shock in these indicators causes changes between 0.03-fold and 0.05-fold in income per capita.     

我国新一轮经济发展与宏观调控政策抉择

宏观调控的目的是为了抵御经济的非正常波动,因而一般来说要逆经济风向而行,采取反周期政策.但另一方面,我国经济的起伏波动在很大程度上是由于政府在不同时期出台的不同宏观经济政策造成的.当前,宏观经济调控背景的转变要求宏观调控手段的转变.从以往的经验来看,熨平经济周期性波动,单一政策效果未必良好,需结合其他政策才能有效地避免或减轻周期性波动的负效应,稳定宏观经济运行.     

Investment climate,outward orientation and manufacturing firm productivity: new empirical evidence

Drawing on the World Bank Enterprise Surveys, we revisit the link between firm-level investment climate and productive performance for a panel of enterprises surveyed twice in time in 70 developing countries and 11 manufacturing industries. We take advantage of the time dimension available for an increasing number of countries to tackle the endogeneity issue stressed in previous studies. We also use pertinent econometric techniques to address other biases inherent in the data (e.g.measurement errors, missing observations and multicollinearity). Our results reinforce previous findings by validating, with a larger than usual sample of countries and industries, the importance of a larger set of environment variables. We show that infrastructure quality, information & communication technologies, skills and experience of the labour force, cost of and access to financing, security and political stability, competition and government relation contribute to firms’ and countries’ performances gap. The empirical analysis also illustrates that firms which choose an outward orientation have higher productivity level. Nevertheless, outward oriented enterprises are more sensitive to investment climate limitations. These findings have important policy implications by showing which dimensions of the business environment, in which industry, could help manufacturing firms to be more competitive in the present context of increasing globalization.
