Industrial Targeting and Non‐shiftable Capital in the Harris–Todaro Model*

This paper shows that, in the 2 × 3 sector‐specific capital Harris–Todaro model, capital growth owing to either domestic or foreign investment always enhances the welfare of the country (i.e. non‐immiserizing), and this result of non‐immiserizing foreign investment holds regardless of initial holdings of foreign capital; the policy of industrial targeting via capital investment is more effective vis‐à‐vis the (neoclassical) 2 × 2 mobile‐capital Harris–Todaro model or the Heckscher–Ohlin model; in contrast to the recent generalization by Marjit and Beladi (2003 ), capital growth cannot be immiserizing in the present model, even if it destroys the “envelope theorem.”     

Multinationals, Endogenous Growth, and Technological Spillovers: Theory and Evidence*

FDI has received surprisingly little attention in theoretical and empirical work on openness and growth. This paper presents a theoretical growth model where MNCs directly affect the endogenous growth rate via technological spillovers. This is novel since other endogenous growth models with MNCs, e.g. the Grossman–Helpman model, assume away the knowledge‐spillovers aspect of FDI. We also present econometric evidence (using industry‐level data from seven OECD nations) that broadly supports the model. Specifically, we find industry‐level scale effects and international knowledge spillovers that are unrelated to FDI, but we also find that bilateral spillovers are boosted by bilateral FDI.     

The economics of poverty traps part one: Complete markets

This paper lists theoretical reasons why neoclassical models of one-sector growth imply that nations with identical economic structures need not converge to the same steady state or balanced growth path, and outlines the empirical significance and policy implications of conditional nonconvergence. We survey poverty traps in both convex and nonconvex economies with complete market structures. Among the potential causes of traps are subsistence consumption; distorted international trade in intermediate inputs; demographic transitions when fertility is endogenous; technological complementarities in the production of consumption goods, financial intermediation services, manufactures, or human capital; coordination failures among voters; various restrictions on borrowing; indivisibilities in human capital formation or child rearing; and monopolistic competition in product or factor markets.     

The Conditional Convergence Properties of Simple Kaldorian Growth Models

Findings of conditional convergence are usually interpreted within a neoclassical growth framework. This follows from the methodology of testing for conditional convergence, whereby the estimating equation is explicitly derived from a neoclassical growth model. Given this explicit derivation, findings of conditional convergence might be thought to discriminate against alternative approaches to growth in general and the Kaldorian approach to growth in particular. This article shows, however, that this is not the case. It does so by examining the conditional convergence properties of the ‘core’ model of Kaldorian growth theory—the Kaldor‐Dixon‐Thirlwall (KDT) model. In particular, the paper demonstrates that this model predicts conditional convergence of a qualitatively identical nature to that predicted by the neoclassical growth model. A simple extension of the KDT model that is reconciled with quantitative estimates of the speed of conditional convergence is also presented.     

Second thoughts on development accounting

The relative roles of factor inputs and productivity are estimated in explaining the level of economic development. For a large sample of countries, it is shown that international differences in factor inputs account for between two thirds and three quarters of international differences in output per worker if alternative identifying productivity assumptions and a quality-adjusted measure of human capital are employed. For a sample of OECD countries, it is found that all differences in output per worker can be attributed to differences in factor inputs, leaving no role for international productivity differences. This result supports the reasoning of a traditional neoclassical growth model.     

Trade deficits in the Baltic states: How long will the party last?

Since their opening up to international capital markets, the economies of Estonia, Latvia and Lithuania have experienced large and persistent capital inflows and trade deficits. This paper investigates whether a calibrated two-sector neoclassical growth model can explain the magnitudes and the timing of the trade flows in the Baltic states. The model is calibrated for each of the three countries, which we simulate as small closed economies that suddenly open up to international trade and capital flows. The results show that the model can account for the observed magnitudes of the trade deficits in the 1995–2004 period. Introducing a real interest rate risk premium in the model increases its explanatory power. The model indicates that trade balances will turn positive in the Baltic states around 2010.     

Increasing PAYG pension benefits and reducing contribution rates

We analyse how a reduced contribution rate affects the balanced pay-as-you-go pension budget in the basic overlapping generations model of neoclassical growth (Diamond, P., 1965. National debt in a neoclassical growth model. American Economic Review 55 (5), 1126–1150). It is shown that PAYG pensions can be increased by reducing the payroll tax paid by the young contributors.     

Trade,Growth, and Environmental Quality*

This paper examines linkages between international trade, environmental degradation, and economic growth in a dynamic North–South trade game. Using a neoclassical production function subject to an endogenously improving technology, North produces manufactured goods by employing labor, capital, and a natural resource that it imports from South. South extracts the resource using raw labor, in the process generating local pollution. We study optimal regional policies in the presence of local pollution and technology spillovers from North to South under both non‐cooperative and cooperative modes of trade. Non‐cooperative trade is inefficient due to stock externalities. Cooperative trade policies are efficient and yet do not benefit North. Both regions gain from improved productivity in North and faster knowledge diffusion to South regardless of the trading regime.     

POPULATION AGING AND INTERNATIONAL CAPITAL FLOWS*

We use the neoclassical growth framework to model international capital flows in a world with exogenous demographic change. We compare model implications and actual current account data and find that the model explains a small but significant fraction of capital flows between OECD countries, in particular after 1985.     

The Optimal Tax Treatment of Housing Capital in the Neoclassical Growth Model

Should housing capital be taxed like other forms of capital? We analyze this question within a version of the neoclassical growth model. We derive the optimal tax treatment of housing capital vis‐à‐vis business capital allowing for relatively general household preferences. In the first‐best, the tax treatment of business and housing capital should always be the same. In the second‐best, in contrast, the optimal tax treatment of housing capital depends on the elasticities of substitution between nonhousing consumption, housing, and leisure. This is because housing taxation may be used to alleviate the distorting effect of taxing labor. As a result, the optimal tax treatment of housing capital may be different from that of business capital. We complement these analytical results with a numerical analysis.     

A CLOSED‐FORM SOLUTION FOR DETERMINING THE BURDEN OF PUBLIC DEBT IN NEOCLASSICAL GROWTH MODELS

This paper develops a new approach, termed as the stock approach, to calculate the steady‐state output loss caused by public debt in neoclassical growth models. The novelty of our stock approach is that it provides a closed‐form solution to the steady‐state output‐debt relationship. The main conclusion of the paper is that the steady‐state burden of public debt is country‐specific in neoclassical growth models and it decreases with the private saving rate and increases with the population growth rate, with the exception of the special case where Ricardian equivalence holds.     

Patterns of International Capital Flows and Productivity Growth: New Evidence

Recent evidence from developing and emerging economies shows a negative correlation between growth and net capital inflows, a contradiction to neoclassical growth theory. I provide updated and disaggregated evidence on the origins of this puzzle. An analysis of the components of capital flows and of gross portfolio positions shows that foreign direct investment is directed towards countries with the highest growth rates, but that portfolio investment outflows exceed these inflows. Liberalized capital accounts further exacerbate this pattern. My results suggest a desire for international portfolio diversification in liquid assets by fast‐growing countries lies at the heart of the puzzle.     

Health and Income Variation – A Panel Data Study on the Developed and Less Developed Economies

In this paper, human capital in the form of ‘health status’ is introduced into a neoclassical economic growth model as one of the main factors differentiating rich and poor countries. Various panel data models are used to examine how health and other growth factors affect average income in different countries. Our main empirical finding indicates that a one-year increase in life expectancy (the health status measure) raises GDP per capita by 0.5–0.9%. Based on this result, a baseline health status can be established to help poor countries achieve a targeted economic growth rate.     

Land,technical progress and the falling rate of profit

The paper sets out a one sector growth model with a neoclassical production function in land and a capital–labour aggregate. If the elasticity of substitution between land and the capital–labour aggregate is less than one and if the rate of capital augmenting technical progress is strictly positive, then the rate of profit will fall to zero. This result holds regardless of the rate of land augmenting technical progress: no amount of technical advance in agriculture can stop the fall in the rate of profit. The paper also discusses the relation of this result to the classical and Marxist literature.     

The analytical solution of balanced growth of non-linear dynamic multi-sector economic model

In a one-sector neoclassical dynamic economic growth model, a reasonable ratio of investment to consumption exists, i.e., the “Golden Rule of Consumption”. This study is to extend one-sector neoclassical growth model to a multi-sector one. It is assumed that both the production function and the utility function are of Cobb–Douglas type, and the analytical expression of the balanced growth solution of the multi-sector model is provided, mainly including analytical expressions of the optimal distribution coefficient of fixed capital investment, the optimal distribution coefficient of labor hour, the proportion of production, the economic growth rate, the rate of change of the price index, and rental rates of different fixed capital.     

Foreign Aid under Quantitative Restrictions: Welfare Effects and International Factor Mobility

Using a two‐country, general‐equilibrium model of international trade, this paper incorporates pre‐existing quantitative trade restrictions and international factor mobility into the transfer problem analysis. The effects of foreign aid on the welfare of both the donor and recipient nations are identified under each form of quantitative trade restriction: quotas and voluntary export restraints (VERs). In doing so, this paper identifies conditions under which international transfers are strictly Pareto‐improving (i.e. increase global welfare). A central result of this analysis is the direct welfare effect of a transfer received by a nation with quota‐constrained (VER‐constrained) imports is enhanced (may be enhanced) by a worsening of the recipient’s terms of trade.     

International capital flows and convergence in the neoclassical growth model

To analyze how capital mobility affects economic growth and convergence, this paper will use the analytical solution to the neoclassical growth model with a constant saving rate, beginning with the closed-economy Solow growth model. An introduction to international capital flows will follow. In an open economy, free capital mobility assures an instantaneous convergence in interest rates that, under a perfect competence situation, implies the instantaneous convergence in income levels among homogeneous countries. Taking into account this question and to reconcile these results with empirical evidence, that is, with the gradual convergence observed, the assumption is introduced that in spite of free capital mobility, there are international credit restrictions. In this case, we will show how the rate of convergence depends on the international capital inflows received.

GROWTH IN THE SHADOWS: EFFECT OF THE SHADOW ECONOMY ON U.S. ECONOMIC GROWTH OVER MORE THAN A CENTURY

Taking a long‐term look at U.S. economic growth over 1870–2014, this paper focuses on the spillovers from the shadow or the unofficial economy to growth in the official sector. Shadow activities might spur or retard economic growth depending on their interactions with the formal sector and impacts on the provision of public goods. Nesting the analysis in a standard neoclassical growth model, we use a relatively new time series technique to estimate the short‐run dynamics and long‐run relationship between economic growth and its determinants. Results suggest that prior to World War II (WWII) the shadow economy had a negative effect on economic growth; however, post‐WWII the shadow economy was beneficial for growth. The sanding effect of the shadow economy in the earlier period is especially robust to alternate considerations of possible endogeneity and an alternate set of growth determinants.

The curse and blessing of fixed specific factors in small-open economies

This paper investigates how a country's specific-factor endowment affects its long-run economic performance. We build an open-economy version of the two-sector neoclassical growth model in which we introduce fixed industry-specific inputs in both activities. We show that differences in input shares between sectors can contribute to explain why nations that seem to have similar factor endowments can show very different income levels. In particular, under (productivity-adjusted) factor-price equalization, larger amounts of factors specific to the industry with a lower (larger) labor share lead the economy to enjoy larger (smaller) long-run income levels. The model can also account for overtaking episodes between countries along their development paths.     

HOUSING IN A NEOCLASSICAL GROWTH MODEL

We present evidence that in the USA, the relative price of housing exhibits secular growth and that its growth rate is a stationary series. The ratio of the value of house stock to either consumption or GDP is also stationary. We develop a two‐sector neoclassical growth model with housing that is consistent with these facts. Among the long‐run determinants of the growth of housing prices and housing stock per capita are factor intensities, rates of technological progress in both the housing and non‐housing sectors, and the excess of population growth over land growth. We also study the model's transitional dynamics.
