Productivity,real exchange rate,and aggregate demand: An empirical exercise applied to Brazil from 1960 to 2011

This research analyzes, from a post Kaleckian perspective, the interactions among the aggregate demand, the real exchange rate, productivity, and real wages in the Brazilian economy from 1960 to 2011. It adopts the longstanding perspective that demand is the driver of capital accumulation and economic growth. The research comprises the following steps: (a) a critical assessment of the growth regime literature, with a particular emphasis on issues related to productivity and the real exchange rate; (b) understanding the relationship between the real exchange rate and the productivity and growth regimes; (c) proposing a theoretical model that relates the real exchange rate, productivity, and the growth regime; and (d) an empirical test of the interaction between the real exchange rate, productivity, and the growth regime. Theoretically the study develops a model showing the interactions between the aggregate demand, the real exchange rate, productivity, and real wages. Furthermore, this research attempts to address the lack of theoretical and empirical studies about the relationship between the aggregate demand, the real exchange rate, productivity and real wages.     

CATCHING‐UP AND TECHNOLOGICAL PROGRESS OF THE ASEAN ECONOMIES

Total factor productivity growth of the five ASEAN founding members is estimated by decomposing total factor productivity growth into technical efficiency and technological progress. By using the stochastic frontier model with individual‐specific temporal pattern of technical efficiency for the period of 1981–2003, the present paper identifies the unique temporal pattern of productivity changes in each country, to analyze the relationship between country characteristics and the inherent efficiency and productivity changes. The empirical results indicate that over the study period, growth in Singapore and Malaysia was largely driven by both technological progress and input accumulation, whereas growth in Thailand was induced by an improvement in technical efficiency and through input accumulation.     

Wages and productivity: the role of labour market institutions in OECD countries

In the context of a monetary union, to keep a territorial equilibrium in terms of economic activity and employment, the relationship between real wages and productivity is crucial. In this paper, empirical evidence about the response of wages to productivity is obtained for 20 OECD countries and the role of labour market institutions to explain differences in this response is analysed.     

Cross‐country evidence on the determinants of inclusive growth episodes

Widening income disparities and slow productivity growth in most advanced and several emerging‐market economies have rekindled interest in the empirical analysis of the determinants of inclusive growth, defined in this paper as episodes of increases in GDP per capita without a concomitant deterioration in the distribution of household disposable income. The empirical analysis is based on a chronology of inclusive growth episodes between 1980 and 2013 for a sample of 78 countries. Logit and multinomial probit estimations show that human capital accumulation, the redistributive potential of tax‐benefit systems, increases in multifactor productivity and labor force participation, as well as trade openness and a range of institutional factors, including political system durability and electoral regimes, are important determinants of the probability of occurrence of inclusive growth. This empirical evidence contributes to the policy debate about how countries can deal with efficiency–equity tradeoffs.

Sources of energy productivity growth and its distribution dynamics in China

The purposes of this paper are to determine the sources of energy productivity growth at the provincial level in China and to examine the relative contributions of the sources and their impacts on regional inequality. Energy productivity change is first decomposed into five components attributable to changes in capital–energy ratio, labor–energy ratio, output structure, and technical efficiency change and technological change. Then a nonparametric analysis is implemented to statistically test the relative contributions of the components and their roles in the distribution dynamics of energy productivity. It is found that (1) changes in capital–energy ratio, output structure, and technological change contribute to energy productivity growth in China, (2) increase in capital–energy ratio caused by capital accumulation is the primary driving force for energy productivity growth, and (3) capital accumulation contributes to energy productivity convergence between Chinese provinces over the time period of 1990–2005.     

East Asia's growth: technology or accumulation?

Krugman, building on the work of Alwyn Young, has argued that hypergrowth in East Asia derives mostly from factor accumulation, owing little to technological change. Yet this explanation is at odds with what analysts of technological change have to say about technology acquisition in these countries. This article examines the Young-Krugman thesis and argues that the problem lies in the misconception of technological change as distinct from accumulation. The critique is taken further by means of a review of the multifaceted way that technology raises the productivity of labor. It is argued that technology is carried not as disembodied knowledge, but as techniques hard-coded in physical devices and structures, by patterns soft-coded in human and organizational capabilities and business-friendly institutions, formal and informal. These operate as symbiotic complements, not separable substitutes as assumed in conventional theory. These arguments are supplemented by perspectives introduced from the technology literature. Since the respective roles and relationship between accumulation and technology are scrutinized, the analysis provides important policy conclusions on the value of East Asian growth strategies.     

Money,Investment and Consumption: Keynes's Macroeconomics Rethought

The dominant supply-side foundation for explanations of the growth potential of an economy is losing its persuasive power in the face of persistent losses in output and employment experienced by mature economies in the aftermath of the financial crisis. There is now an opening for eclectic approaches that consider the interaction between supply-side and demand-side factors in shaping macroeconomic outcomes. In this paper, we develop a model that reflects such an approach to interpreting differential productivity growth over the long run, and then present empirical results for several countries. On the supply-side, the model considers the linkage between the intensity and efficacy of the accumulation process and the gains of productivity in terms of a Kaldorian Technical Progress Function. Then, drawing on the Evsey Domar's Keynesian notion of dynamic equilibrium as the growth rate that reconciles additions to capacity with the absorption of aggregate output by demand, we derive a locus for a ‘Domar equilibrium path’. Imbalances caused by excess aggregate supply or demand, and by the effects of ‘shocks’ are presented and discussed using a simple graphical framework. In the empirical analysis, an error-correction model is applied to the fundamental relationship between the rate of growth of product per work-hour and the rate of capital accumulation. The results suggest that the differences in productivity growth among countries are can be explained in terms of the efficiency of their ‘accumulation paths’.     

The impact of process innovations on firm's productivity growth: the case of Spain

The main aim of this paper is to investigate about the effect that a measure of the process innovation performance of a firm has on its labour productivity growth. This analysis is mainly a consequence of two considerations. The first one results from a clear differentiation of the role that product and process innovations have on a firm's performance. The second one is to assume that the knowledge capital of a firm is mainly composed by its successful research. The study demonstrates that process innovation has a positive and significant effect on firm's productivity growth. Moreover, this result is robust under a wide range of alternative specifications and, in any case, the variable behaves much better than R&D intensity. Following previous research, the detected quadratic relationship between vertical product differentiation and process innovation performance leads to the existence of some firms for which there exist a trade–off between quality and productivity.

How Important Are Scale Effects for Growth When Knowledge Is a Public Good?

In this paper, by proposing an R&D accumulation law for an economy with an expanding number of firms, I seek to reconcile the following three facts: the positive relationship between the fraction of income allocated to R&D expenditure and growth; the positive relationship between the number of firms and total factor productivity growth; and knowledge as a non‐rival and non‐excludable good. There are scale effects because of the public nature of knowledge, but the economy also grows in the absence of population growth. I find that population growth explains one‐fifth of market income growth but only one‐sixteenth of efficient income growth.     

China's Growth Slowdown: Labor Supply,Productivity, or What?

There has been much discussion of the sources of China’s growth slowdown but little formal econometric analysis of this question. Chen and Groenewold (2019) show that the slowdown was primarily supply-driven, but they stopped short of identifying specific supply variables. This paper extends their analysis and distinguishes several potential supply components: labor supply, productivity, and capital accumulation. Our results confirm their main conclusion that supply dominates the explanation of the slowdown. A model with two supply factors (labor supply and productivity) reveals that both components contribute to the slowdown, although productivity makes the greater contribution. However, when capital stock is added to the model, the decline in the capital accumulation rate becomes an important factor in the growth slowdown, to some extent replacing the effects of both labor supply and productivity.

Culture and labour productivity: An empirical investigation

Culture is considered as one of the most powerful forces that shape human behaviour and thereby economic activity. This paper investigates the effects of culture on labour productivity and examines the cultural traits driving this relationship. Using panel data analysis, empirical evidence is provided covering a sample of 34 OECD countries over a wide period of three decades. Our empirical results suggest a significant positive relationship between the cultural background and labour productivity. The main channels of this positive impact are control and work ethic environment, while obedience has a negative impact on productivity. These findings are robust to a series of robustness checks, including alternative cultural measures, additional control variables, various country samples, and alternative specifications.

A real and monetary analysis of capitalism

Building on ideas of Joseph Schumpeter, this paper constructs and compares a real and a monetary model of capitalism. The paper’s thesis is that real and monetary analysis are both necessary for describing the capitalist cycle. The real model is in four parts. The first part is a simplified static Walrasian exchange. The second part uses a time dynamic to show price and productivity equilibrium over time. The third part defines surplus-value, capital, accumulation, profit and producer’s surplus. The fourth part defines economic evolution and long-term analysis. Each of the four parts has a corresponding Mathematica program and a table of sample data. The real model shows a relationship between long term average profit, GDP and capitalization. A monetary model is then constructed which empirically defines monetary and real products, the capital-market, the real economy and investment. The monetary model is first described under conditions of laissez-faire. The concepts of appreciation, overinvestment and the capitalist cycle are defined with the aid of the real model. Finally, the post laissez-faire capitalist cycle is described with an emphasis on the government policies of post 1980 capitalism. The conclusion of the paper—based on the real and monetary models—is that post 1980 capitalism changes but does not eliminate the capitalist cycle because government policies do not address over-investment, rather these policies abet over-investment.     

Technological change,efficiency gains and capital accumulation in labour productivity growth and convergence: an application to the Spanish regions

The main objective of this article is to analyse labour productivity growth and convergence in the Spanish regions between 1965 and 1995, decomposing total factor productivity gains into technological progress and efficiency change by means of Malmquist productivity indices. On the basis of this decomposition, labour productivity growth is broken down into components attributable to technological change (shifts in the frontier), efficiency gains (movements toward the frontier) and capital accumulation (movements along the frontier). The approach followed in this study is based on work initiated by Färe et al., where a link between the economic growth and convergence literature and the production frontier approach was established. Furthermore, in the spirit of Quah's approach, the evolution of the whole distribution is considered. Thus, the analysis of the dynamics of the entire distribution of labour productivity and the factors behind it – technological progress, efficiency gains and capital accumulation – combine both approaches, yielding new insights into the process of productivity growth and convergence experienced by the Spanish regions over the last 30 years.
