Growth and Wage Inequality in a Dual Economy

Who benefits from economic growth? This paper analyses the distributional impact of different types of growth within a two‐sector model. The paper first presents necessary and sufficient conditions for unambiguous changes in wage inequality in a dual economy, based on analysis of the entire Lorenz curve. These conditions are then applied to the Harris–Todaro model with an urban non‐agricultural sector and rural agriculture. It is shown that capital accumulation or technical progress in agriculture can shift the Lorenz curve inwards and reduce wage inequality, while the effects of development in non‐agriculture are typically ambiguous.     

Product Market Imperfection and the Two‐sector Harris–Todaro Economy

This paper examines the ramifications of market imperfection for a dual economy in the context of the two‐sector Harris–Todaro model with the agricultural (manufacturing) sector under perfect competition (monopoly). Based on a utility function of constant elasticity of substitution variety, it demonstrates (i) existence of a unique equilibrium at which the consumer price ratio and the producer price ratio are synchronized; (ii) several fundamental properties of the model (crucial to extended research on this subject area); (iii) contrary to an earlier result obtained under an oligopolistic manufacturing sector, trade liberalization for a small economy may be immiserizing.     

Fiscal Spending,Relative‐Price Dynamics,and Welfare in a World Economy*

This paper analyzes the dynamics of a 2 × 2 × 2 Heckscher–Ohlin model where foreign asset holdings and capital accumulation are independently determined by optimizing agents. Each country has two production sectors, both of whose products are used for consumption, and an investment sector, which uses one of the two commodities to accumulate real capital. In this setting we examine the effects of fiscal spending on the equilibrium paths of interest rates and prices and each country's lifetime utility. The welfare effect is found to consist of the static terms‐of‐trade effect, the dynamic foreign asset effect and the direct income‐loss effect.     

Technical progress,urban unemployment,outputs, and welfare under variable returns to scale

This paper analyzes the implications of technical progress for a small Harris–Todaro (H–T) economy under variable returns to scale (VRS). It is shown that under VRS, technical progress occurring either in the agriculture or the manufacturing may be immiserizing; the effects of technical progress on sectoral outputs, factor prices, urban unemployment, and welfare crucially depend on the signs and the relative magnitudes of sectoral elasticities of returns to scale and the employment effect; the Corden–Findlay type of ultrabiased output effect of technical progress in the constant returns to scale (CRS) H–T model carries over to the case of VRS, but with much more stringent conditions than the CRS case.     

Foreign Capital, Urban Unemployment, and Economic Growth

A three-sector endogenous growth model, is used to study the effects of foreign direct investment (FDI) on the dynamics of urban unemployment, labour income, and capital income as well as national welfare in a Harris–Todaro economy. It is shown that more FDI can affect the economy's dynamics and national welfare positively or negatively. The paper derives conditions as to how the growth rate and welfare effects of FDI relate to the intersectoral mobility of capital, the destination of FDI, the elasticities of substitution, and the factor intensities of the final good production.     

The Optimal Environmental Tax and Urban Unemployment in an Open Economy

This paper investigates how a rise in the urban pollution tax rate may affect urban unemployment and welfare in a small open Harris–Todaro (HT) model with intersectoral capital mobility. First, by formulating urban pollution as a dirty input in manufacturing, we find that an increase in the urban pollution tax rate can increase the level of urban unemployment even with intersectoral capital mobility. That is, the optimistic finding by Rapanos (2007 ) that environmental protection policy reduces urban unemployment in the long run does not always hold. Second, the (sub)optimal pollution tax rate under urban unemployment is higher than the Pigouvian tax rate (the marginal damage of pollution). This result opposes those of Beladi and Chao (2006 ) for a closed HT economy and that of Tsakiris et al. (2008 ) for an open HT economy with sector‐specific capital.     

Aid,non‐traded goods,and growth

Abstract We examine the effects of foreign aid in a small recipient country with two traded goods, one non‐traded good, and two factors. Learning by doing and intersectoral knowledge spillovers contribute to endogenous growth. We obtain two main results. First, a permanent increase in untied aid raises (or lowers) the growth rate if and only if the non‐traded good is more capital intensive (or effective labour intensive) than the operating traded good. Second, a permanent increase in untied aid raises welfare if the non‐traded good is more capital intensive than the operating traded good; otherwise, it may raise or lower welfare.     

Foreign Capital,Spillovers and Export Performance in Emerging Economies: Evidence from Indian IT Firms

The role of foreign capital inflow, foreign direct investment (FDI) and foreign portfolio investment (FPI), on export behavior of both recipients and non‐recipient competing firms in the same sector often guides economic development policy. By using panel data of Indian IT firms over 2000–2006, we show that FDI reduces the sunk costs of entering foreign markets and therefore positively effects both the decision to export and the export propensity of recipient firms. Foreign portfolio investment has no effect on the decision to export, but it does marginally increase the volume of exports. Further, these positive FDI and FPI recipient effects do not spill‐over to non‐recipients.     

Saving–investment Association and Regional Capital Mobility in China: A Nonparametric Panel Approach

Using a nonparametric panel data model, this paper estimates the degree of time‐varying and province‐specific capital mobility in China during 1970–2006. We estimate the savings–investment association, that is, the savings retention rate à la Feldstein and Horioka, as a measure of capital mobility. We also split the total savings (investment) into private and government savings (investment) to explore the role of government in improving capital mobility. Over time, we find an improvement in capital mobility after the mid‐1990s. Across provinces, we observe higher capital mobility in eastern/coastal regions. From the 1990s, the government is found to play a less important role in promoting capital mobility. Across provinces, the government is found to be more important in either the municipalities (Shanghai and Beijing) or the less developed inland provinces.     

Shouldn't Physical Capital Also Matter for Multinational Enterprise Activity?

The foreign direct investment (FDI) literature has generally failed to find strong systematic evidence of “vertical” motivations in bilateral aggregate FDI and foreign affiliate sales (FAS) data, despite recent evidence of vertical FDI in firm‐level data. Moreover, a Bayesian analysis of the empirical determinants of FDI (and FAS) flows reveals that the parent country's physical capital per worker has a strong positive effect on FDI alongside typical gravity‐equation variables; however, this variable is ignored in the knowledge‐capital (KC) model and most empirical work. We address these two puzzles by introducing relative factor endowment differences into the three‐factor, three‐country knowledge and physical capital extension of the 2 × 2 × 2 KC model. Using a numerical version of our model, we show that horizontal and vertical multinational enterprises' (MNEs') headquarters surface in different parts of the Edgeworth box relating the parent country's skilled labor share relative to its physical capital share (of the parent's and host's endowments). The key economic insight is that horizontal MNE headquarters will be relatively more abundant than vertical MNE headquarters in countries that are abundant in physical capital relative to skilled labor, because of the multi‐plant (single‐plant) structure of horizontal (vertical) MNEs—assuming plants (headquarters) use physical capital (skilled labor) relatively intensively in their setups. The theoretical relationships suggest augmenting empirical FAS gravity equations with (polynomials of) the parent's skilled labor share alongside the parent's physical capital share to explain in aggregate bilateral data the coexistence of horizontal and vertical FAS. The theoretical and empirical results shed light on the positive effect of parent's physical capital share on FAS flows, but also suggest that MNE headquarters may be prominent in parent countries with relatively high and low skilled labor shares—once physical capital is accounted for—a result not suggested by the two‐factor KC model.     

Foreign Direct Investment in Australia Following the Australia–US Free Trade Agreement

A model of inward foreign direct investment for Australia is estimated. Foreign direct investment is found to be positively related to economic and productivity growth and negatively related to foreign portfolio investment, trade openness, the exchange rate and the foreign real interest rate. Foreign direct investment is found to be a substitute for both portfolio investment and trade in goods and services. The exchange rate and the US bond rate affect foreign direct investment through the relative attractiveness of domestic assets. Actual foreign direct investment outperforms a model‐derived forecast in recent years, consistent with the liberalisation of foreign investment screening rules following the Australia–US Free Trade Agreement.     

Population and Economic Growth Under Different Growth Engines

Using a growth model with physical capital accumulation, human capital investment and horizontal R&D activity, this paper proposes an alternative channel through which an increase in the population growth rate may yield a non‐uniform (i.e., a positive, negative, or neutral) impact on the long‐run growth rate of per‐capita GDP, as available empirical evidence seems mostly to suggest. The proposed mechanism relies on the nature of the process of economic growth (whether it is fully or semi‐endogenous), and the peculiar engine(s) driving economic growth (human capital investment, R&D activity, or both). The model also explains why in the long term the association between population growth and productivity growth may ultimately be negative when R&D is an engine of economic growth.     

Getting help from abroad: The macroeconomics of foreign direct investment in infrastructure in low‐income countries

Infrastructure financing needs in most low‐income countries are substantial, but funding for such needs is only partly covered by national governments and aid donors. This paper introduces foreign direct investment (FDI) through public–private partnerships as a source of infrastructure financing in low‐income countries. A two‐sector open economy model is developed to assess the macroeconomic performance of FDI in infrastructure. With efficient foreign investment, an increase in revenue‐generating infrastructure investment boosts productivity and spurs private investment while stabilizing domestic prices. A direct comparison between infrastructure financed by domestic versus foreign investment shows that foreign investment creates higher output growth and welfare gains and is preferable to domestically sourced investment, irrespective of the underlying financing instrument the domestic economy is employing. FDI in non‐revenue‐generating infrastructure is also analyzed and discussed.     

Taxi,Takeoff and Landing: Behavioural Patterns of Capital Flows to Emerging Markets

This paper analyses volatility, persistence, predictability, correlation, comovement (or contagion risk) and sudden stop (reversibility) of capital flows (foreign direct investment (FDI), foreign portfolio equity investment, long-term and short-term debt flows) using time series econometric techniques for 24 emerging economies over 1970–2014. This is informative on the pattern and relationship between capital inflows, with implications for accommodating macroeconomic policies in countries receiving inflows. The paper also addresses the predictions of conventional theory, that differences are associated with the maturity of the capital (long-term vs. short-term), with the information-based trade-off model of Goldstein and Razin [(2006). An information-based trade off between foreign direct investment and foreign portfolio investment. Journal of International Economics, 70(1), 271–295], that differences are associated with the structure of the capital (equity vs. debt). In line with the latter, equity flows (FDI and portfolio) are less volatile and persistent, more predictable and less susceptible to sudden stops than debt flows. Contrary to conventional theory, short-term flows are not more volatile, but there is evidence that correlations and risks of contagion are strong within all capital flow components.     

STATE‐LEVEL CAPITAL AND INVESTMENT: UPDATES AND IMPLICATIONS

This paper presents state‐by‐state capital stock and gross investment estimates for 1990–2007. I follow the methodology of Garofalo and Yamarik (The Review of Economics and Statistics, 84, 2002, 316–23) and apportion the national capital stock to the individual states using one‐digit NAICS income data. I then test the soundness of the data by estimating a Cobb–Douglas production function and a Solow growth model using a variety of panel data estimators. Under both models, I obtain estimates of the output elasticity for capital that are plausible and close to the observed national income share of one‐third. (JEL O47, O51, R11)     

Tariff Reductions in the Presence of Foreign Direct Investment

This paper argues that the welfare effects of trade liberalization in the presence of foreign direct investment obtained under perfect competition cannot be extended to imperfectly competitive markets. In the Heckscher-Ohlin model, trade liberalization may be paradoxically immiserizing when the traditional welfare-increasing result is corrected for the change in foreign capital revenue. Under imperfect competition this cannot occur, except under rather implausible assumptions. Indeed, a tariff reduction is expected to increase welfare when the welfare indicator is corrected for the presence of foreign capital, regardless of the type of market structure and the form of competitive rivalry.     

Heterogeneity and Spatial Dependence of Regional Growth in the EU: A Recursive Partitioning Approach

We use model‐based recursive partitioning to assess heterogeneity of growth and convergence processes based on economic growth regressions for 255 European Union NUTS2 regions from 1995 to 2005. Spatial dependencies are taken into account by augmenting the model‐based regression tree with a spatial lag. The starting point of the analysis is a human‐capital‐augmented Solow‐type growth equation similar in spirit to Mankiw et al. (1992, The Quarterly Journal of Economics, 107, 407–437). Initial GDP and the share of highly educated in the working age population are found to be important for explaining economic growth, whereas the investment share in physical capital is only significant for coastal regions in the PIIGS countries. For all considered spatial weight matrices recursive partitioning leads to a regression tree with four terminal nodes with partitioning according to (i) capital regions, (ii) non‐capital regions in or outside the so‐called PIIGS countries and (iii) inside the respective PIIGS regions furthermore between coastal and non‐coastal regions. The choice of the spatial weight matrix clearly influences the spatial lag parameter while the estimated slope parameters are very robust to it. This indicates that accounting for heterogeneity is an important aspect of modeling regional economic growth and convergence.     

Comparative advantage and strategic specialization

This paper shows that a strong comparative advantage is necessary for free trade and specialization in a 2 × 2 symmetric Ricardian model to be achieved in a Nash equilibrium. Governments strategically control labor distribution across industries, and representative agents maximize Cobb–Douglas utilities. A Nash equilibrium with complete specialization is achieved if and only if relative productivity exceeds a key value of 3, which is considered a very large number based on previous empirical studies. This paper also introduces a two‐stage game where each government chooses labor distribution first and then tariffs. In this two‐stage game, complete specialization is never achieved for any relative productivity level. Finally, by generalizing the Cobb–Douglas model into constant elasticity of substitution (CES) preferences, I show that if immiserizing growth effects exist, complete specialization could not be achieved for any level of relative productivity.     

Sector-specific minimum wages,economic growth,and some policy implications

Economic growth is introduced in the urban unemployment model of Harris and Todaro. It is shown that in the steady state, the optimal savings ratio is greater than the golden rule savings ratio under full employment. Also the optimal proportion of total investment allocated to the urban sector is not necessarily higher than the optimal proportion under full employment.     

China's Capital and ‘Hot’ Money Flows: An Empirical Investigation

We examine time‐series characteristics of China's capital flows during 1998–2014. More specifically, we employ Kalman filtering state‐space models to gauge the relative importance of permanent and transitory components in China's overall foreign direct investment (FDI), equity, bond, other investment and bank credit flows. Our results show that only in the case of FDI are both gross inflow and net flow dominated by a permanent stochastic level, suggesting that this source of capital is largely permanent. Incorporating covariates into the state‐space models, we find that a larger difference between onshore and offshore renminbi interest rates encourages capital inflows that are dominated by a transitory component. Greater global risk perception, proxied by S&P 500's volatility index, in contrast, discourages them. These covariates imply that capital control may not be effective in stemming volatile and speculative flows. Our results on bilateral capital flows between China and the USA also suggest that these flows are less persistent and more volatile during 1998–2014 than previously found based on 1988–1997 data. Our results bear important policy implications as China engages in further reforms in its domestic financial system and greater integration with the world financial system.
