Three Simple Techniques to Analyze a Complex Economic Phenomenon: The Case of Profits

This paper seeks to characterize the behavior of profits over the business cycle as a model for analyzing any economic series by a practicing business economist. It addresses three fundamental questions about profits that are common and critical to identifying the behavior of any macroeconomic series—mean-reversion, volatility, and trend. First, does profit growth over time exhibit mean-reverting behavior? Second, how volatile are profits, and does this volatility obscure the message of average profit growth? Third, how can we estimate a long-run trend growth component for profits and thereby separate profit cycles from its long-run trend growth component?     

Book reviews

This paper analyzes how fiscal policies and credit constraints can affect the impact of macroeconomic volatility on long-run growth. The model by Aghion et al. (2005) is extended by allowing for governmental fiscal policy over the business cycle. The analysis shows that in an economy facing credit constraints, an increase in volatility will result in lower mean growth, and all the more the less financially developed and the more procyclical the fiscal policy is. The main implication is that in countries with lower degrees of financial development, countercyclical fiscal policies are particularly important in reducing the negative consequences of adverse aggregate shocks on firms' long-run investments. An empirical analysis is finally conducted using different groups of countries that confirm the theoretical predictions.     

Does International Trade Cause Economic Growth? A Survey

This study surveys the literature on the relationship between international trade and economic growth, and succinctly reviews the role of GATT/WTO in fostering free trade. Most studies support the gains of trade and recognise the substantive contributions of GATT/WTO in fostering free trade; the evidence is, however, not ubiquitously unambiguous. The macroeconomic evidence provides a dominant support for the positive and significant effects of trade on output and growth, while the microeconomic evidence lends larger support to the exogenous effects of productivity on trade, as compared to the effects of trade on productivity. The GATT/WTO remains surrounded by barriers to trade and avowed preferences for preferential trade agreements. The strength of the argument for the gains of trade needs to be evaluated in juxtaposition with several methodological and measurement issues that surround the trade‐growth empirics. Most studies focus on partial equilibrium analysis of trade policy and ignore the general equilibrium aspects of macroeconomic policy. It is difficult to disentangle the effects of trade policies from those of other macroeconomic policies and unequivocally interpret the observed correlations between trade policies and economic growth. Trade is one of the several catalysts of productivity and growth and hence its contribution is contingent on its weight in economic activity.     

On exports and economic growth: the case of Italy

The export-led growth hypothesis for the Italian economy (1960-98) is tested through a VAR model with four macroeconomic variables: an index of the GDP of the rest of the world; the Italian real exchange rate; Italian real exports; and the Italian real GDP. Our results provide clear empirical support for the hypothesis. They also suggest that the Kaldorian approach is very useful in analysing short-run as well as long-run growth and fluctuations of an open economy such as Italy.     

The income inequality,financial depth and economic growth nexus in China

Income inequality has increased in China despite rapid economic growth. Income inequality could impinge on future development, leading to social tension or political instability. Our study investigates the short-run and long-run relationship between three important macroeconomic indicators—income inequality, economic growth and financial depth. We utilise a two-step procedure of ARDL bounds and Granger causality for the analysis. The bounds test indicates the presence of a cointegrating relationship between income inequality, financial depth and economic growth in the long run. In the second step, we utilise the Granger causality approach. Results show a bidirectional causality between financial depth-growth and a unidirectional causality between inequality-growth in the short run. In the long run, results reveal that growth and financial depth determine Gini. Our findings provide support for the inequality-widening effect due to economic growth and higher credit provided to the private sector. We find no evidence of inequality-narrowing or income-equalising effect in the long run for the period of study. It is possible that the government's inclusive growth policies which started less than a decade ago have not taken effect for us to capture the inverted U-shape income equalising effect significantly.     

企业间反需求状况定价行为:价格总水平的“内在稳定器”

运用重复博弈的方法建立了一个企业间长期价格竞争模型,用于论证这样一个机制:随着市场需求的波动,企业为实现自身利益最大化所采取的非合作定价行为会与市场需求状况呈相反方向,从而对宏观价格总水平起到一种稳定器的作用。同时对该模型在我国的应用及模型本身可能存在的问题进行了探讨。     

A Note on Impacts of International Trade on Economic Growth and Inflation

Results of this study indicate that short- and long-term effects of international trade on inflation, GDP, and inflation-adjusted GDP growth vary over periods with fixed or freely floating exchange rates or a big accumulated trade deficit. Causalities between trade and other macroeconomic variables are also different in different periods.

This study does not find supportive evidence that “phantom GDP gains” may significantly change impacts of imports on productivity, CPI, and inflation-adjusted GDP and causalities between imports and other macroeconomic variables, although a structural break is found in the relationship between imports and GDP at the beginning of 2003.     

Estimating the speeds of long-run technological catch-up and growth of total factor productivity for countries

This paper constructs a dynamic production frontier function under the framework of a forward-looking rational expectations model, taking the effect of quasi-fixed inputs into account. The sample comprises balanced panel data of 36 countries over the period from 1990 to 2009. Evidence is found that all of the four country groups show the technological catch-up phenomenon in the long run and experience total factor productivity (TFP) growth. Their TFP growth is primarily driven by long-run technical efficiency improvement, followed by technological progress. The Non-G7 and Non-NICs groups are the top two groups in terms of speeds of long-run technological catch-up and rates of TFP growth.     

Musings on the Macroeconomic Effects of Oil Price Increases

In considering the macroeconomic effects of oil price increases, it is important to be mindful of whether changes come from the supply or demand side and whether they are accompanied by impacts on financial markets. Also, it is important to know whether a change is likely to be temporary or permanent and whether it can be offset by policy responses. Finally, the short-run effects of oil price changes are likely to be different from the long-run effects. This paper explores these questions and their ramifications for macroeconomic growth.     

Total factor productivity and macroeconomic instability

Total factor productivity (TFP) is an important component of growth for most countries. This article assesses the role of macroeconomic instability on TFP growth. We consider volatility in inflation, openness of an economy and financial market deepness as measures of macroeconomic instability. Empirical evidence provided from Turkey suggests that volatility of openness and financial market deepness reduce TFP growth, whereas volatility of inflation increases TFP growth.     

Real exchange rate targeting and macroeconomic instability

Using an optimizing model of a small open economy, this paper studies the macroeconomic effects of PPP rules whereby the government increases the devaluation rate when the real exchange rate—defined as the price of tradables in terms of nontradables—is below its long-run level and reduces the devaluation rate when the real exchange rate is above its long-run level. The paper shows that the mere existence of such a rule can generate aggregate instability due to self-fulfilling expectations. The result is shown to obtain in both flexible- and sluggish-price environments.     

The effects of stock market development on growth and private investment in lower-income countries

Recent literature argues that stock market liberalisation has positive long- and short-run effects on macroeconomic growth and private investment, respectively. However, given a sample of up to 64 countries from 1981 through 1998, positive results for long-run growth are largely dependent on the inclusion of higher-income countries in regression samples, which limits the relevance for lower-income nations. Indeed, some evidence in this study indicates that stock market development has a more positive impact on growth for greater levels of per capita GDP, lower levels of country credit risk, and higher levels of legal development. Similarly, using a sample of 26 countries from 1981 through 1998, lagged equity price appreciation seems to boost private investment growth in the short-run, but only in rich countries. All in all, these results imply subdued enthusiasm regarding emerging equity market development.     

贸易开放度、产业专业化与中国经济增长研究

许多研究表明贸易开放度与中国经济增长存在显著的正相关关系,然而进一步的协整分析和改进的Granger因果检验显示:贸易开放度对中国经济增长并不存在直接的长期作用机制。为解释上述问题,本文构造了产业专业化指数来分析其影响机制,研究结果显示,以生产率为权重的产业专业化指数能够较好地刻画贸易开放度与中国经济增长的相互作用机制。贸易开放度的增加,加快优势行业的技术进步,导致生产率较高行业的专业化生产,从而促进中国经济的长期增长。     

Explaining cross-country differences in exporting performance: The role of country-level macroeconomic environment

In this paper, we undertake a meta-analysis to investigate whether country-level macroeconomic factors can help explain the inconclusiveness of existing evidence on the firm-level productivity–exporting relationship – the so-called learning-by-exporting hypothesis. Using 34 studies that investigate learning by exporting covering 31 countries, we attempt to explain whether country-specific macroeconomic factors account for the variation in the estimated firm-specific productivity effects from exporting across different studies, along with considering a firm-level factor. Robust to different specifications, one interesting finding is that countries with bigger external demand (measured by distance-weighted global GDP for each country) are likely to display a higher estimate of the productivity effect of exporting. In addition, countries with higher competitiveness, as reflected in lower relative prices, tend to experience higher exporting performance, while higher returns from overseas production reduce the learning effect from exporting at the firm level. The results also indicate that the effect of exporting on firm productivity is lower in periods of financial crisis.     

Business Dynamics and Efficiency in Industries and Regions: The Case of Spain

High rates of firm births and deaths are a pervasive phenomenon across industries and territories. Most studies have related the great turbulence at the fringe of practically all manufacturing industries to positive effects on the long-run performance of industries. According to these views business turbulence, although it has a relatively small incidence on net entry, leads to allocative improvement and stimulates innovation. The existing set of empirical studies does not reach clear conclusions, however, and many questions are still open. Our contribution analyses the relationship between business dynamics in manufacturing and the growth of total factor productivity in industries and regions. After a review of current literature on entry and exit it is argued that most models are tailored to suit the processes observed in industries and regions that are near the technological frontier, and we propose an approach that could be more representative of middle range economies such as Spain. According to this approach new firms are seen more as users of innovations than producers of innovations. We adopt a model based on a vintage capital framework in which new entrants embody the edge technologies available and exiting businesses are supposed to represent the most marginal obsolete plants. Both industries and regions are represented by a Hall's type production function which controls for imperfect competition and economies of scale. The results show that both entry and exit rates contribute positively to the growth of total factor productivity in industries and in regions.     

Capital Subsidies and the Performance of Firms

In many countries, governments grant different capital subsidies to the business sector in order to promote growth. Also the EU, provides this type of subsidies. As De Long and Summers (1991) suggest there may be market failure justifications for public subsidisation of firms. However, because the use of subsidies may cause problems, it is far from clear how they affect long-run economic growth. This study examines the effects on total factor productivity of public capital subsidies to firms in Sweden between 1987 and 1993. Panel data which distinguish between subsidised and unsubsidised firms in the manufacturing industry are used. The results suggest that subsidisation can influence growth, but there seems to be little evidence that the subsidies have affected productivity.     

U.S. Economic Prospects: Secular Stagnation,Hysteresis, and the Zero Lower Bound

The nature of macroeconomics has changed dramatically in the last seven years. Now, instead of being concerned with minor adjustments to stabilize about a given trend, concern is focused on avoiding secular stagnation. Much of this concern arises from the long-run effects of short-run developments and the inability of monetary policy to accomplish much more when interest rates have already reached their lower bound. This address analyzes contemporary macroeconomic problems and proposes solutions to put the U.S. economy back on a path toward healthy growth.     

CAN THE POOR COUNTRIES CATCH UP? MIXED RESULTS FROM EXTENDED SOURCES OF GROWTH PROJECTIONS FOR THE EARLY 21st CENTURY

Illustrative projections of per capita income gaps between two groups of developing economies and the rich economies for the period 1998–2030 are made on the basis of an extended sources of growth equation which accounts for interactions between trends in capital and labor productivity. The equation takes into consideration Kaldor–Verdoorn effects, possible impacts on labor productivity of trade liberalization and/or astute industrial policy, human and physical capital accumulation, employment and population growth, shifting shares of labor in income and traded goods in output, shifts in capital productivity, productivity growth retardation due to convergence and specific regional effects. Under optimistic assumptions about all these factors and in the historically unprecedented absence of adverse macroeconomic shocks over three decades, relative and absolute convergence of both regions to the rich countries may be possible.     

Economic Benefits of Gender Equality in the EU

To analyse how gender equality measures can contribute to economic growth in the EU, the European Institute for Gender Equality studied the impacts of reducing gender inequalities in areas relevant from a macroeconomic perspective: STEM education, labour market activity and pay. It also considered the demographic changes that would take place if these gender gaps are reduced and a more equal distribution of unpaid care work between women and men is achieved. The study is the first of its kind to use a robust econometric model to estimate a broad range of macroeconomic benefits of gender equality at the EU level. The results of the modelling show that improved gender equality would have a largely positive effect on GDP per capita and on employment of women. The positive impacts are due to an increase in productivity and an improvement to the potential productive capacity of the economy.
