Resource Price,Macroeconomic Distortions,and Public Outlay: Evidence from Oil-Exporting Countries

This study examines the repercussions of oil price and macroeconomic distortions on government expenditure in 15 oil-exporting countries. Adapting the Pooled Mean Group analytical approach, the long-run findings are indicative of a blend of the Dutch disease and rent-seeking hypothesis of the resource curse theory in oil-exporting countries. These effects crucially impact on the poor growth of the real sector in these countries, needed for diversification of their revenue base. Furthermore, both resource curses account for one of the reasons why fiscal deficits in oil-exporting countries have been on the rise. The country short-run coefficient for the balance of payment, economic growth, and exchange rate also supports the Dutch disease and rent-seeking hypothesis mix found in the long run. Also, the significant negative impact of oil rents in most countries shows that oil-exporting countries have been making attempts at diversifying their income sources; this is because proceeds from oil cannot be relied upon to adequately finance growing government expenditure, due to the volatile nature of oil prices, thus suggesting also that the volatility hypothesis is valid for most oil-exporting countries in the short run.     

Optimal Dutch disease

Growth models of the Dutch disease explain why resource abundance may reduce growth. The literature, however, also raises a new question: if the use of resource wealth hurts productivity growth, how should such wealth be optimally managed? This question forms the topic of the present paper. We show that the assumptions in the previous literature imply that the optimal share of national wealth consumed in each period needs to be adjusted down. Some Dutch disease, however, is always optimal. Thus, lower growth in resource-abundant countries may not be a problem in itself, but may be part of an optimal growth path. The optimal spending path of the resource wealth may be increasing or decreasing over time. What might be contrary to intuition is that the bigger is the growth generating traded sector, the more of the resource income should be spent in early periods.

The Development Problem under Embodiment

This paper studies technology adoption in an optimal growth model with embodied technical change. The economy consists of the final good sector, the capital sector, and the technology sector which role is the imitation of exogenous innovations. Scarce labor resources are allocated to the technology and final good sectors. The final good is allocated to consumption and to the capital sector. The authors analytically characterize the long run optimal allocations. Using a calibrated version of the model, they find that an acceleration in the rate of embodied technical change should not be responded by an immediate and strong adoption effort. Instead, adoption labor should decrease in the short run, and the optimal technological gap is shown to increase either in the short or in the long run. The state of the institutions and policies around the technology sector is key in the design of the optimal adoption timing.     

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.

A turnpike property of optimal programs for a class of simple linear models of production

Summary. This paper establishes a ‘turnpike theorem’ for a closed linear model of production with a primitive input requirement matrix. Optimal programs of resource allocation have a ‘turnpike property’ if the growth factor of every sector in the economy converges, in the long run, to a common value. The usefulness of such a theorem is due to the fact that the input requirement matrix for an economy with a large number of goods may be primitive (some power of the matrix is strictly positive).

Trend movements and inverted Kondratieff waves in the Dutch economy, 1800–1913

This paper presents the results of an effort to dissect 19th century economic growth in the Netherlands into two principal long run components: the domain of the trend and the domain of long waves. Spectral and cross-spectral analysis is used to identify Kondratieffs in volume series. It appears that the long term pattern of development is composed of an inverse S-shaped trend and a Kondratieff wave that is superimposed upon it. Contrary to the British case, long waves in Dutch volume series appear to run contrary to the corresponding long waves in price series. This finding is at variance with the received view on long waves. This typical result is explained by so-called ‘Keynes effect’ in combination with the characteristics of a small open economy that has to dance to the tune of the dominant British economy.     

HUMAN CAPITAL ACCUMULATION,HOME PRODUCTION AND EQUILIBRIUM DYNAMICS*

In this paper, we construct a three‐sector endogenous growth model in which long‐run growth is propelled by human capital accumulation. We show that although the addition of a home sector to the standard two‐sector endogenous growth model preserves the well‐behaved balanced growth equilibrium properties, it generates new transitional dynamics around the balanced growth path. It is shown that, when there is a positive shock to physical capital, our model is more likely to exhibit paradoxical growth than are standard multisector endogenous growth models that exclude home production. Our analysis adds new results to those from the related literature on leisure.

Fiscal policy reforms in general equilibrium: The case of Greece

This paper quantifies the macroeconomic and welfare implications of (i) changes in the tax-spending mix and (ii) debt consolidation policies. The setup is a neoclassical growth model augmented with a relatively rich public sector. The model is calibrated to the Greek economy. The results suggest that, if the goal of fiscal policy is to stimulate the economy and increase welfare by changing the tax mix, then it should decrease the tax rate on labour income and increase the consumption tax rate. While higher public investment spending is good for the economy, it is lower public consumption spending that is found to be expansionary. The results also suggest that both tax- and expenditure-based debt consolidation policies lead to worse economic activity in the short run, but they have strong beneficial effects in the medium and long run when the consolidation period finishes.     

TAXES, GROWTH AND THE CURRENT ACCOUNT TICK-CURVE EFFECT

This paper examines the dynamic and long run effects of a shift from income taxes to consumption taxes in a growing small open economy. We introduce a government sector that maintains a balanced budget and expenditure at a constant proportion of domestic income to a small open economy Swan-Solow model. Our framework provides a previously unidentified dynamic effect that is robust to endogenising the savings rate. Lowering the income tax rate promotes economic growth and has a tick-curve effect on the current account balance, characterised by instantaneous deterioration, a period of recovery and gradual convergence to an improved position in the long run.     

Dutch Disease in Australia: Policy Options for a Three‐Speed Economy

‘Dutch Disease’ refers to the adverse effects through real exchange rate appreciation that the mining boom can have on various export‐ and import‐competing industries. The distinction is made between the booming sector (mining), the lagging sector (exports not part of the booming sector and import‐competing goods and services) and the non‐tradeable sector. What should the government do to reduce this Dutch ‘disease’? The principal options are: do nothing, piecemeal protectionism, moderate exchange rate effects by running a fiscal surplus, combined with lowering the interest rate, and possibly establishing a sovereign wealth fund. The costs of the latter measures may be considerable.     

Does Intelligence Affect Economic Diversification?

This paper extends the growing literature on knowledge economy by investigating the effect of intelligence on economic diversification. Using a battery of estimation techniques that are robust to endogeneity, we find that human capital has positive correlations with export diversification, manufactured added value and export manufactures. This empirical evidence is based on a world sample of 170 countries for the year 2010. The findings have significant implications for the fight against the Dutch disease. In essence, investing in human capital could bring economic diversity and therefore dampen negative external shocks related to resource‐dependence. Other knowledge‐economy implications are discussed.     

Endogenous Growth and Natural Resource Scarcity

Endogenous growth theory has rekindled interest in the role of innovation in determining long-term economic growth. Generally, this body of literature has ignored the contribution of natural resources to growth or the role of innovation in overcoming resource scarcities. The latter problem has been a focus of resource economics for many years, but innovation is usually modelled as exogenous rather than endogenous technological change. Recent investigations in political economy have additionally suggested that the supply of innovation may itself be constrained by resource scarcities, especially in the developing world. The following paper attempts to bridge these theoretical gaps through the formal analysis of two issues: First, a simple Romer-Stiglitz model of endogenous growth with resource scarcity and population growth is developed to determine the optimal balanced growth path for the economy. Second, the basic model is extended to allow for the possibility of resource availability constraining the supply of innovation, so that in the long run innovation net of any resource constraint is zero. However, under the latter conditions it is still possible to avoid resource exhaustion and thus achieve a constant level of per capita consumption in the long run. The paper therefore demonstrates that endogenous growth can overcome resource scarcity, but the outcome in the long run depends critically on assumptions concerning any constraints imposed by resource availability on the generation of innovation.     

Demographic change and economic growth: The role of natural resources in the MENA region

This paper analyses the conditional effect of demographic change on economic development in the MENA region. We employ fixed-effects panel analysis on data from 19 countries in the region and demonstrate a negative impact of natural rents on the relationship between the working-age population and economic growth. Once the critical level of approximately 16% of resource rents (as share in total GDP) is reached, a one-unit increase in working-age population appears to harm economic growth. Further tests show that this finding is mainly driven by the negative effects of resource rents on female labor force participation. However, other drivers are a large public sector, low private sector development and inefficient labor market policies and issues such as the “Dutch disease”. The main finding remains after robustness checks in the form of controlling for competing hypotheses. Policy makers are advised to encourage economic diversification, female employment and private sector development.     

Lobbying, the Composition of Government Expenditures, and the Politics of Fiscal Policy

This paper constructs a one sector growth model to examine the impact of political lobbying on the formation of fiscal policy. The model predicts that lobbying can induce endogenous regime switches, development traps, and a sub-optimal allocation of government expenditures between productive and unproductive ends, leading to long run income losses in the economy. A calibrated version of the model is used to generate estimates of the dynamic social costs of lobbying by estimating the optimal savings rates necessary to induce balanced growth in the economy. Finally, the model predicts that lobbying may influence the growth of government.     

Nature, Power and Growth

This essay reviews the relationship between natural–resource abundance and economic growth around the world, and presents some new results. The principal reasons why resource–based production can inhibit economic growth over long periods are traced to the Dutch disease, neglect of education, rent seeking, and economic policy failures. Across a large number of countries in the period from 1965 to 1998, the share of the primary sector in the labour force is shown to be inversely related to exports, domestic and foreign investment, and education, and directly related to external debt, import protection, corruption, and income inequality. The cross–sectional data show, moreover, that the share of the primary sector in the labour force is inversely related to per capita growth across countries. None of this lies in the nature of things, however. What seems to matter for economic growth is not the abundance of natural resources per se, but rather the quality of their management, and of economic management and institutions in general.     

Endogenous Growth and Publicly Funded Knowledge Accumulation

We investigate a centrally planned, infinite horizon, single good economy in which new knowledge is generated in a separate R&D sector with government subsidy. The rate of growth of new ideas is assumed to be linear in the amount of labor devoted to R&D. Perpetual growth in per capita output and consumption is sustained by the spillover effects of knowledge creation. Using an isoelastic social welfare function and a general production function, the unique balanced growth path is characterized and the conditions for balanced growth to take place derived. In analyzing standard balanced growth, we demonstrate that so long as physical capital and knowledge grow at some arbitrarily constant rates along an optimal time path, the two rates must necessarily be equal. Using a Cobb–Douglas production function, the dynamic evolution of the economy is explicitly described in closed form for each state and control variables. In particular, it is shown that the economy either (i) attains the balanced growth path from the initial time, or (ii) converges monotonically to the balanced growth path. An asymptotic balanced growth path along which labor input in manufacturing tends to zero in the long run is ruled out by the tranversality condition on knowledge.     

Trade liberalization,firm entry,and income inequality

This paper examines the short‐ and long‐run effects of trade liberalization via tariff reductions on income inequality in an economy, which is characterized by an imperfectly competitive urban manufacturing sector and a perfectly competitive rural agricultural sector. Tariff reductions reduce domestic output in the importable urban manufacturing sector, leading to shifts of capital from the urban sector to the rural agricultural sector. This can narrow the wage gap between skilled and unskilled labor in the short run. However, the lowered capital cost attracts new firms, and subsequently excessive entry of firms, to the urban manufacturing sector. This firm entry effect can mitigate the favorable effect of tariff reductions on wage inequality in the long run. Empirical study confirms the findings.     

The impact of the informal economy on R&D,wage inequality and economic growth

We extend the existing research and development (R&D) growth literature by focusing on the short–medium–long run effects of the informal sector on R&D intensity, wage inequality and economic growth, and by considering 18 OECD countries between 1990 and 2008. We show that: the steady state is unique and stable; the share of informal economy (IE) in production affects negatively R&D intensity and wage equality; Nordic countries have the lowest share of IE in production, while Mediterranean countries have the highest share of IE, wage inequality and R&D intensity but R&D spillovers are lower.
