Intangible Capital and Labor Productivity Growth: Panel Evidence for the EU from 1998–2005

Using new international comparable data on intangible capital investment by business within a panel analysis between 1998 and 2005 in an EU country sample, a positive and significant relationship between intangible capital investment and labor productivity growth is detected. This relationship proves to be robust to a range of alterations. The empirical analysis confirms previous findings that the inclusion of business intangible capital investment in the asset boundary of the national accounting framework increases the rate of change of output per hour worked more rapidly. In addition, intangible capital is able to explain a significant portion of the unexplained international variance in labor productivity growth, and becomes a dominant source of growth.     

“Price Levels and Economic Growth: Making Sense of Revisions to Data on Real Incomes”: A Comment

In his recent paper, Ravallion (2013) proposes a new method to predict changes in purchasing power parities (PPPs), arguing that a model that includes economic growth and exchange rate movements is superior to the standard approach of using inflation differences. In this comment, I argue that his test is wrong and I show that with a correct specification of the test, there is no robust and stable relationship between changes in PPPs and economic growth while the usefulness of the standard approach is confirmed. I also suggest an approach that could be more helpful to understand changes in PPPs.     

Price Levels and Economic Growth: Making Sense of Revisions to Data on Real Incomes

The price surveys from the 2005 International Comparison Program (ICP) imply substantially lower levels of GDP at purchasing power parity (PPP) for many developing countries than prior estimates. While some observers have questioned the data, this paper argues that the pattern of changes in PPPs between ICP rounds makes economic sense. Consistently with the original Balassa–Samuelson model, more rapidly growing economies experienced steeper increases in their PPPs relative to official exchange rates. This effect was even stronger for poor countries. Taking account of this effect would reduce the need for such large data revisions when new ICP data become available.     

Habit Formation, Catching Up with the Joneses, and Economic Growth

Our objective is to investigate how alternative assumptions about preferences affect the process of economic growth. To do this, we analyze a neoclassical growth model under three alternative preference specifications: (i) time separable, (ii) catching up with the Joneses, and (iii) habit formation. Departing from the time separable specification leads to important differences in the dynamic structure, the adjustment path followed by key economic variables, the correlation patterns implied by the time series generated by the model, and the speed of convergence to the new steady state. In the catching up with the Joneses economy the differences arise from a consumption externality, while in the habit formation economy the difference arises from the fact that agents not only smooth consumption but also its rate of change.     

Two‐level CES Production Technology in the Solow and Diamond Growth Models*

The two‐level CES aggregate production function—that nests a CES into another CES function—has recently been used extensively in theoretical and empirical applications of macroeconomics. We examine the theoretical properties of this production technology and establish existence and stability conditions of steady states under the Solow and Diamond growth models. It is shown that in the Solow model the sufficient condition for a steady state is fulfilled for a wide range of substitution parameter values. This is in sharp contrast with the two‐factor Solow model, where only an elasticity of substitution equal to one is sufficient to guarantee the existence of a steady state. In the Diamond model, multiple equilibria can occur when the aggregate elasticity of substitution is lower than the capital share. Moreover, it is shown that for high initial levels of capital and factor substitutability, the effect of a further increase in a substitution parameter on the steady state depends on capital–skill complementarity.     

China as Number One: How about the Renminbi?

Using simulations projecting Chinese economic growth into the future, this paper first examines when China will overtake the USA to become the largest economy. Demographic changes that affect economic growth are taken into consideration in these projections. China is expected to become number one sometime in the mid-2020s, unless its growth rate of gross domestic product per worker declines dramatically, à la the lost decade of Japan. Next, the paper examines whether China becoming the number one economy will mean its currency, the renminbi (RMB), will become the international key currency. According to the basket currency regressions during the period that Chinese currency was gradually appreciating against the US dollar from July 2005 to August 2008, it is shown that the RMB has already acquired a strong influence on the Asian currencies. This shows that the RMB is fast gaining the status of a regional anchor currency for a possible regional joint float. As the Chinese government proceeds with internationalization of its currency, the RMB is expected to gain in the ranking of other aspects of international currency, such as the store of value and the medium of exchange.     

Social Exclusion and Economic Growth: An Empirical Investigation in European Economies

The aims of this article are to propose an overall index of social exclusion and to analyze its relationship with economic growth in European countries. We approach social exclusion as a multidimensional phenomenon by a three‐mode principal components analysis (Tucker3 model). This method is applied to estimate an indicator of social exclusion for 28 European countries between 1995 and 2010. The empirical evidence shows that in the short run: (1) Granger causality runs one way from social exclusion to economic growth and not the other way; (2) countries with a higher level of social exclusion have higher growth rates of real GDP per capita; and (3) social exclusion has a larger effect than income inequality on economic growth. The policy implication of our analysis is that social inclusion is not a source of economic growth in the short term.     

Estimating Purchasing Power Parities from Household Expenditure Data Using Complete Demand Systems with Application to Living Standards Comparison: India and Vietnam

This study departs from the previous literature on purchasing power parity (PPP) by proposing a demand system based methodology for calculating the PPP that takes account of consumer preferences and allows for the substitution effect of price changes. The methodology is used to calculate the PPP between the Indian Rupee and the Vietnamese Dong. The study allows for regional variation in preferences and price changes both inside the country and between countries. It proposes and applies a methodology for constructing prices from unit values after adjusting them for quality and demographic effects. The adjusted unit values are used as prices in the demand estimations, and the demand parameter estimates are used to calculate both spatial prices within each country and the PPP between the two countries within a consistent framework. The study illustrates the usefulness of preference consistent methods to calculate the PPP by applying the PPPs to compare living standards between India and Vietnam. The significance of the results follows from the fact that the levels of living comparisons are quite sensitive to the PPP used in converting the Rupee expenditure into Vietnamese Dong. The present results on food PPPs question the relevance of the PPPs from the ICP project in cross‐country welfare comparisons especially in a period of high food inflation.     

Growth and convergence in South–South integration areas: An empirical analysis

Until recently, it has been argued in economic theory that regional integration and trade agreements among developing countries may achieve negative growth effects. This study tests empirically the effects of such South–South agreements on growth and convergence. All three world regions in question are considered: South America, Southeast Asia, and Sub‐Saharan Africa. A comprehensive panel data analysis is conducted that distinguishes between the problems of testing for stronger growth and accelerated convergence, respectively. The data indicate that the considered South–South agreements promote both.     

To Save or to Consume: Linking Growth Theory with the Keynesian Model

In the neoclassical growth theory, higher saving rate gives rise to higher output per capita. However, in the Keynesian model, higher saving rate causes lower consumption, which may lead to a recession. Students may ask, "Should we save or should we consume?" In most of the macroeconomics textbooks, economic growth and Keynesian economics are in separate, sometimes unsequential, chapters. The connection between the short run and the long run is not apparent. The author builds a bridge between the neoclassical growth theory and the Keynesian model. He links the Solow diagram and the IS-LM curves and depicts the short-run to long-run transition of the economy after changes in saving and other macroeconomic policies.
