Note on positive lower bound of capital in the stochastic growth model

In the context of the classical stochastic growth model, we provide a simple proof that the optimal capital sequence is strictly bounded away from zero whenever the initial capital is strictly positive. We assume that the utility function is bounded below and the shocks affecting output are bounded. However, the proof does not require an interval shock space, thus, admitting both discrete and continuous shocks. Further, we allow for finite marginal product at zero capital. Finally, we use our result to show that any optimal capital sequence converges globally to a unique invariant distribution, which is bounded away from zero.     

Location of trade,return comovements,and diversification benefits: Evidence from Asian country ETFs

Using data from the Asian country ETFs and their MSCI indices, this paper examines whether trading location affects return comovements and diversification benefits. Our empirical results show that the magnitude of return comovements for the Asian country ETFs is higher than the corresponding MSCI indices. Moreover, our empirical findings indicate that the factors, including investor sentiment, market conditions, and economic fundamentals of the U.S. market, have greater effects on the return comovements for the Asian country ETFs than their underlying MSCI indices. Finally, the evidence presents a higher diversification benefit for the Asian MSCI indices than the Asian country ETFs.     

International diversification of manufacturing operations: Performance implications and moderating forces

The strategic importance of diversifying international manufacturing for firms with global operations has been extensively documented in a series of studies. There is a lack of studies, however, of the performance implications of strategically spreading manufacturing operations across the globe. In fact, most research on international manufacturing to date has generalized from findings by researchers that examine international diversification at the level of the whole value chain, rather than specifically looking at the performance impact of dispersing production operations. Building on the concept of international manufacturing diversification, we show that its relationship with financial performance is inverted U-shaped, and that this relationship is positively moderated by product diversification and co-location of manufacturing and sales activities in the same geographic market. We place the development of international manufacturing diversification processes in the context of the resource based view and transaction costs economics. Hypotheses are tested using data on 38 firms with home base in 15 countries and car and light truck production activities in 45 countries from 2002 to 2008.     

Sharing risk within and across countries: the role of labor market institutions

This paper studies the effect of labor market institutions on within- and cross-country risk sharing, using a model of international trade in risky assets modified to include a subset of agents, labor-owners who do not access financial markets, and employment security provisions. Labor market, institutions, by promoting within-country risk-shifting arrangements between agents with or without, access to financial markets, reduce the fluctuations of non-tradable labor incomes and amplify the, fluctuations of capital incomes. Capital flows become more volatile across countries, and if the, configuration of labor markets differs across countries, capital-owners bear the burden of systematic, undiversifiable world aggregate uncertainty.     

Factor taxation and labor supply in a dynamic one-sector growth model

This paper studies a class of AK-type growth models with factor income taxes, public capital stock and labor–leisure trade offs. While a higher capital tax rate reduces economic growth in the short run, the long-term growth effect is ambiguous and remains ambiguous even if the level of tax rate is larger than the degree of government externality. A higher labor income tax rate has ambiguous growth effects both in the short and long runs. However, if the intertemporal elasticity of substitution for labor supply is sufficiently small, a higher labor tax rate always lowers economic growth in the long run, despite the existence of productive government taxation.     

The relationship between trade,FDI and economic growth in Tunisia: An application of the autoregressive distributed lag model

The relationship between foreign direct investment (FDI), trade openness and economic growth in host countries remains one of the most important issues in the economic literature and met with renewed interest in recent years mainly for countries suffering from unemployment problems and lack of technological progress. This paper examines this issue for Tunisia by applying the bounds testing (ARDL) approach to cointegration for the period from 1970 to 2008. The bounds tests suggest that the variables of interest are bound together in the long run when foreign direct investment is the dependent variable. The associated equilibrium correction is also significant, confirming the existence of a long-run relationship. The results also indicate that there is no significant Granger causality from FDI to economic growth, from economic growth to FDI, from trade to economic growth and from economic growth to trade in the short run. Even though there is a widespread belief that FDI can generate positive spillover externalities for the host country, our empirical results fail to confirm this belief for the case of Tunisia. They go against the generally accepted idea considering the positive impact of FDI on economic growth to be automatic. The results found for Tunisia can be generalized and compared to other developing countries which share a common experience in attracting FDI and trade liberalization.     

A world trade model based on comparative advantage with m regions,n goods,and k factors

This paper describes the World Trade Model, a linear program that determines world prices, scarcity rents, and international trade flows based on comparative advantage in a world economy with m regions, n goods, and k factors. The new model generalizes the World Model of Leontief et al. (1977) in ways that make it particularly useful for analyzing scenarios about sustainable development. Major properties of the model are demonstrated, and sources of the gains from trade are identified for the world as a whole and for individual regions. Illustrative results are reported for a 10-region, 8-good, 3-factor model of the world economy.     

A two-country dynamic model of international trade and endogenous growth: Multiple balanced growth paths and stability

We formulate a two-country endogenous growth model, which explain joint determination of long-run trade patterns and world growth rates. After providing the existence and local stability of the continuum of balanced growth paths, we show that main standard trade propositions hold under some modifications and that, subject to certain conditions concerning social and private rankings of factory intensities between production sectors, the higher is the growth rate, the smaller is the volume of international trade among balanced growth paths in the continuum.

Public banking and economic growth: The experiences of 10 countries since the 1950s until 2017

Despite the limited number of empirical works assessing the implications of public banks for economic growth, a wave of these institutions has arisen since 2000. With this in mind, this paper investigates the linkage between these banks and long-run growth in 10 countries. We find discouraging evidence on the role of these institutions in the growth process as public banks contributed to long-run economic growth in only two countries. More precisely, the public bank raised the gross domestic product in the Dominican Republic and investment in Singapore. In the remaining eight countries, long-run growth was harmed, or we did not find a long-run nexus running from the public bank. This is particularly surprising because some public banks in our sample have a long history of proper management and were given an important role in their country's development. We find long-run reverse causality in five countries, and, in all of them but in one, a larger gross domestic product per capita expanded public banks’ assets. Therefore, public banks were following the economic cycle. Considering all this, governments that aim to accelerate economic growth should be more cautious about the creation or promotion of these entities.     

Financial Markets, Development and Economic Growth: Tales of Informational Asymmetries

Abstract.  The development of financial systems is very often characterised by the development of innovative financial contracts which allow a more efficient allocation of resources and a higher level of capital productivity and economic growth. By exploiting the microeconomic theory of the optimal financial contract under asymmetric information, economists have recently managed to shed new light on the well studied issue of the relationship between financial market development and economic growth. This paper reviews the most recent progress of this literature which shows that the amount of information asymmetry in the credit market and the degree of heterogeneity between borrowers (typically firms) and lenders (typically workers or savers) determine the nature of the financial system. Differences in endowments and in the level of information distribution can give rise to very different financial contracts which affect, and in turn are affected, by capital accumulation and growth.     

Market‐oriented institutions and policies and economic growth: A critical survey

Abstract.  This paper surveys recent evidence suggesting that market‐oriented institutions and policies are strongly related to economic growth, focusing on studies using the economic freedom (EF) indicator of the Fraser Institute. This index is critically discussed. Also various serious shortcomings of empirical studies using this index are identified. Nevertheless, there are strong indications that liberalization, i.e. an increase in the EF index, stimulates economic growth. This paper also reviews studies on the determinants of EF. Political liberalization is often found to enhance economic liberalization, whereas there is less evidence for causality running in the other direction.

Measuring digitization: A growth and welfare multiplier

Digitization encapsulates the social transformation triggered by the mass adoption of digital technologies that generate, process and transfer information. The digitization index introduces a global measure of national performance reflecting ubiquity, affordability, reliability, speed, usability and skills. Output and welfare rise with the index while manifesting increasing returns to scale some implications for ICT public policy are drawn from these findings.     

Money,random matching and endogenous growth: A quantitative analysis

In this study, we develop a search-and-matching monetary growth model to analyze the effects of inflation on economic growth and social welfare by introducing endogenous economic growth via capital externality into a two-sector search-and-matching model. We find that the channel through which inflation affects economic growth in the search-and-matching model is different from the traditional cash-in-advance model. To facilitate the calibration, we obtain an empirical estimate of the effects of inflation on economic growth using panel regressions. In the simulation analysis, we quantitatively evaluate the welfare effect of inflation in the search-and-matching endogenous growth model and compare it to a search-and-matching exogenous growth model. We find that the welfare effect of inflation is nonlinear in the endogenous growth model whereas it is linear in the exogenous growth model. Furthermore, we find that the welfare cost of inflation under endogenous growth is up to four times as large as the welfare cost of inflation under exogenous growth.     

The impact of foreign trade issues on economic growth in some developing countries including Iran and Turkey

The issue of foreign trade and economic growth have been on the economic agenda for centuries. Foreign trade is a facilitator of goods and services exchange in the global marketplace and is an engine of economic growth in a country. Moreover, economic growth is a means to improve the output, employment opportunities, and welfare, which in turn could make a favorable impact on the positive foreign trade balance. Economic growth is also an essential component of country competitiveness in international markets. Yet, the objective of this study is to analyze the correlation between foreign trade and economic growth in some developing countries, including Iran and Turkey, by using econometrics applications (panel co-integration method and E-views software), also resting on credible national and international publications. Thus, it is estimated in the study that foreign trade has a positive impact on economic growth, resource allocation, energy and green energy consumption, human capital development, and physical capital consumption.     

Similarity of emerging market returns under changing market conditions: Markets in the ASEAN-4, Latin America,Middle East,and BRICs

We studied the risk-return distances of 18 emerging stock markets in the period from January 2000 to December 2013. Distances are linked to volatility and time-varying correlations estimated in standard and asymmetric DCC models. Our results revealed a positive relationship between risk-return distances and volatility, which means that during more volatile periods, the risk-return characteristics in emerging markets exhibit lower similarity to the characteristics found in developed markets. This result seems to be in sharp contrast to most empirical studies using correlations. Within the portfolio framework, our results suggest that diversification into emerging stock markets may still provide desirable benefits to international investors.     

The non-observed economy and economic growth: A meta-analysis

Academics, politicians, the public in general and researchers have great interest in the non-observed economy. However, there is divergence in its definition, accounting methodology and economic effects. In this paper we conduct a meta-analysis on the empirical literature that estimates the impact of the parallel economy on economic growth. We conclude that there is no publication bias and that the average effect of the parallel economy on economic growth is insignificant. However, the reported effects differ considerably with the type and number of countries included in the sample of primary studies, the structure of the data, the methodology used to measure the parallel economy, the number of citations of primary studies, and the year they were published.     

A portfolio approach to endogenous growth: equilibrium and optimal policy

This paper develops a portfolio approach to modeling endogenous growth in continuous time that is especially suitable for addressing fiscal and financial issues in policy design. The analysis focuses on the equilibrium relationship between fiscal and financial policy, rates of return and wealth allocation. We analyze two models. The first is based on the Arrow-Romer model with increasing returns and an external effect of capital on labor productivity. The second draws on Barro's analysis of government spending and endogenous growth. In both models, we study the equilibrium allocation and discuss the optimal fiscal and financial policy.
