The Role of Natural Resources in Economic Development

Economists now recognize that, along with physical and human capital, environmental resources should be viewed as important economic assets, which can be called natural capital. Three recent debates have emerged over the role of natural capital in economic development. First, as many ecological services are unique, does the environment have an “essential” role in sustaining human welfare, and if so, are special “compensation rules” required to ensure that future welfare is not worsened by natural capital depletion today? Second, the environmental Kuznets curve (EKC) hypothesis has fostered empirical estimations of an “inverted U” shaped relationship between a variety of indicators of environmental pollution or resource depletion and the level of per capita income. Does the existence of such EKC relationships suggest that environmental degradation will eventually decline with growth? Finally, recent economic theories and empirical evidence have questioned whether lower income economies that are endowed with abundant natural resources develop more rapidly than economies that are relatively resource poor. Is it possible that resource abundant economies are not reinvesting the rents generated from natural resource exploitation into productive assets, or that resource booms actually divert economic resources from more productive and innovative sectors?     

Progressive taxation and human capital as determinants of inflation persistence

In this study, we introduce progressive taxation and human capital differences across productive sectors into a typical monetary policy game. The objective of this work is to reveal the potential short-run effects of these two typical features of economic growth on inflation dynamics. In our framework, such features act as frictions of labor mobility across sectors. We show that an increased progressivity of taxation lowers the diffusion of shocks, and in turn increases inflation persistence. Moreover, the dispersion of human capital across sectors acts as a barrier to labor mobility and thereby increasing inflation inertia through the same channel. We also empirically verify these findings by employing panel data analysis in a sample of 28 OECD countries.     

Capital Constraints and Employmen

Abstract
This article considers whether capital is a significant constraint on employment in Australia. We calculate the level of capital-constrained employment for seven sectors of the Australian economy. The calculations suggest that the manufacturing; transport, storage and communication; and recreation, personal and other services sectors have sufficient capital installed to increase employment. In two other sectors, mining and wholesale and retail trade, the potential for increases in employment through increased capital utilisation may be constrained by surplus labour (as of June 1993). While some sectors are capital constrained at the moment, we find that the investment requirements to increase employment in these sectors are not onerous. We also project investment requirements in each of the sectors for employment growth over the next five years. These projections suggest that a jump in investment followed by relatively modest growth is required to sustain growth in employment.     

On some criteria for the formulation and testing of economic growth models

This paper presents a methodology for the formulation and testing of economic growth models. The model selected includes two production sectors with physical and human capital accumulation. These capital stocks are associated with spillover effects in the production of the physical good and in the accumulation of both factors.     

Long-Run Effects of Monetary Expansion in a Two-Sector Model of Endogenous Growth

This paper explores the long-run effects of monetary expansion by introducing a cash-in-advance constraint into one of the basic models of endogenous growth. In our model, the real side of the economy consists of two production sectors, one of which produces a final good that can be used either for consumption or for investment and the other produces new human capital. Both sectors use physical and human capital under constant returns to scale technologies. We first characterize the balanced-growth equilibrium and then examine how a rise in money growth affects the relevant variables, such as the long-term growth rate and the relative prices.     

General equilibrium with trade balance and real interest rate parity

This paper demonstrates, in the context of a two-sector OLG neoclassical growth model, conditions under which international trade in consumption goods alone may be sufficient for the equalization of real returns to physical capital across countries; that is, under which commodity arbitrage is sufficient for real interest rate parity (RIRP). This role for repeated commodity arbitrage is established via a dynamic extension of the factor price equalization (FPE) theorem which is valid at all dates comprising the equilibrium path as well as its steady state. The results are at odds with the conventional view regarding RIRP which arises from open one-sector growth models, in which case steady state trade balance and RIRP are irreconcilable, and are also a contradiction to frequent assertions of lon-run specialization in two-sector frameworks. An equilibrium path for an integrated world economy yields an endogenous, time-variant cone of diversification which implies sufficient conditions for the dynamic paths of a cross-section of economies to exhibit FPE, and hence RIRP with trade balance, at all points in time. These conditions require that the savings rates and initial capital-labor ratios of individual countries do not deviate too significantly from world averages, and that both sectors absorb capital easily. The first of these requirements is sufficient to establish steady state FPE and RIRP in the general specification. The first two requirements are sufficient for the entire equilibrium path to be characterized by FPE and RIRP in a log-linear example.

Growth,economic structure,and residential distribution of a small city

This article presents a growth model of a small open city with economic structure and geography. The city which is located along a line segment has three, industrial, services and housing, sectors. The spatial growth model of a small city synthesizes the main ideas in some important models in the neoclassical growth theory, urban economics, and the literature of economic growth of small open economies. We show that the dynamic system has a unique equilibrium. We also simulate the motion of the urban economy over time and space. The unique feature of our approach is to treat production activities, economic structure, residential distribution, capital accumulation, and consumption on the basis of microeconomic mechanism as an integrated whole. Our simulation provides some important insights into the processes of the urban economic growth. For instance, under certain conditions, when the industrial sector’s productivity is increased, the wage rate, price of services, capital intensities of the services and industrial sectors, and per-worker output levels of the two sectors are increased. The total labor supply, the capital stocks employed by the three sectors and the labor forces by the service and industrial sectors are all increased. The shares of the three sectors are not affected by the technological change in the long term, even though the shares are initially affected. The per capita consumption level of the industrial goods rises and the consumption level of services falls. The land and housing rents are increased and the consumption of housing per household falls. Moreover, the current account balance tends to be more in surplus and the growth rate is increased.     

Costly Factor Reallocation and Reduced Productivity Effects in International Trade

Most models of international trade assume extremes of factor mobility between productive uses. From perfectly mobile factors in the Heckscher–Ohlin model, to fixed capital and mobile labor in the Ricardo–Viner–Jones model, factors are assumed to move costlessly or not at all. In reality, factors are neither perfectly mobile nor fixed. This paper considers costs of reallocating factors between industries, deriving a measure of adjustment costs due to factor specificity in a two‐period model of a firm's input allocation decision. The degrees of specificity for labor and capital are then estimated based on data for 15 industries in 16 countries covering eight years. Estimating a system of nonlinear first‐order conditions using a three‐stage least squares technique, I find that recently reallocated factors are indeed less productive. Labor is 14% less productive in the period after reallocation, while capital productivity falls by 43%. Thereafter, capital, unlike labor, moves quickly toward full productivity.     

Catching-up and Regulation in a Two-Sector Small Open Economy

Deregulation is often aimed at reducing mark-up pricing in technologically stagnant sheltered sectors. The paper shows that this may decrease the process of catching-up and welfare since it shifts resources away from R&D-intensive tradables sectors. Catching-up and deregulation are analyzed in an R&D-based growth model that allows for international capital mobility, trade, and spillovers. Knowledge spillovers raise the productivity of R&D in the exposed sector which results in catching-up. In the long run, the economy grows at the exogenous world growth rate. Capital mobility speeds up convergence. Temporary shocks have long-lasting effects as the economy exhibits hysteresis.     

On the interaction between public and private capital in economic growth

This paper introduces two forms of interaction between private and public capital in an endogenous growth model in which productive government expenditure takes the form of a stock-variable and public capital is used in part as an input in the production of final output and in part to increase its own supply. While the first form of interaction involves the stocks of the two capital-goods and takes place within the final output sector through the specification of the aggregate production function (Cobb?CDouglas vs. CES), the second one concerns the rates of investment in the two kinds of capital. The share of productive public expenditure devoted to output production can be either exogenous or endogenous. Our results suggest that when this share is exogenous, along the balanced growth path the optimal growth rate of the economy is a positive function of the degree of complementarity between the two forms of investment. When the share of productive public expenditure devoted to output production is endogenous, the public capital share in GDP becomes, along with the model??s preference parameters, an important determinant of the economy??s long run growth. We also find that the optimal growth rate is an increasing function of the elasticity of substitution between public and private capital inputs in goods production, and is independent of the complementarity/substitutability between the two forms of investment.     

The transmission of bank capital requirements and monetary policy to bank lending in Germany

We investigate the transmission of changes in bank capital requirements and monetary policy, and their interaction, on German banks’ corporate loan growth and lending rates. Our results show that increases in capital requirements are associated with an immediate decrease in total domestic and cross‐border bank lending. Changes in the euro area's monetary policy stance are positively related to corporate loan interest rates in general. Regarding the interacting effect of national bank capital requirements and euro area monetary policy, we observe that the transmission of accommodative euro area monetary policy to corporate lending rates can be attenuated by contemporaneous increases in bank capital requirements. Moreover, more strongly capitalized banks increase their loan growth in response to accommodative monetary policy whereas, for weaker banks, increasing capital requirements implies a decrease in their corporate loan growth. Our results confirm a tradeoff between higher capital requirements and accommodating monetary policy originating from banks’ capital constraints.     

Capital Malleability, Emission Leakage and the Cost of Partial Climate Policies: General Equilibrium Analysis of the European Union Emission Trading System

Computable general equilibrium (CGE) models are the premier analytical platform for assessing the economic impacts of climate change mitigation. But these models tend to treat physical capital as “malleable”, capable of reallocation among sectors over the time-period for which equilibrium is solved. Because the extent to which capital adjustment costs might dampen reallocation is not well understood, there is concern that CGE assessments understate the true costs of greenhouse gas (GHG) reduction policies. This paper uses a multi-region, multi-sector CGE model to investigate cap-and-trade schemes, such as the European Union Emission Trading System which cover a subset of the economy, elucidating the effects of capital malleability on GHG abatement, the potential for emission leakage from abating to non-abating sectors, and the impacts on welfare. To simplify the complex interactions being simulated within the CGE model, that analysis is complemented with an analytical model. A partial climate policy results in negative internal carbon leakage, with emissions declining not only in capped sectors but also in non-regulated ones. This result is stronger when capital is intersectorally mobile. Interestingly, in partial climate policy settings capital malleability can amplify or attenuate welfare losses depending on the attributes of the economy.     

Efficiency change,technological change and capital accumulation in Italian regions: a sectoral study

This paper examines the sources of labour productivity in the Italian regions during the period 1980–2004. Five economic sectors are investigated using data envelopment analysis (DEA) and taking into account productive specialisation and sector inefficiencies. Labour productivity change is decomposed into five components by means of Malmquist productivity indices: intra-sector efficiency change, composition efficiency change, input-biased technical change, magnitude component technical change and capital accumulation. Using bootstrap procedure, the components of labour productivity changes are statistically tested. Efficiency analysis shows that productive specialisation is not a source of inefficiency and efficiency gains can be obtained by sector-specific policies. Thus, it is possible to obtain improvements in efficiency in each sector of activity rather than reallocating resources among sectors. The results of the decomposition by sectors reveal heterogeneous sources of growth. The total economy has shown evidence of non-neutral technical change and, it has been found that agriculture, industry and construction experienced capital using technical change. The analysis of the decomposition of the labour productivity growth is complemented by an analysis of β-convergence.     

Factor market distortions across time,space and sectors in China

In this paper, we measure TFP losses in China?s non-agricultural economy associated with labour and capital misallocation across provinces and sectors between 1985 and 2007. We also decompose the overall loss into factor market distortions within provinces (between state and non-state sectors) and distortions between provinces (within sectors). Over the entire period, misallocation lowers aggregate non-agricultural TFP by an average of twenty percent. However, after initially declining, these losses increased appreciably beginning in the mid-1990s. This reversal can be attributed almost exclusively to increasing misallocation of capital between state and non-state sectors within provinces, while losses from between province misallocation remained fairly constant. We argue that the recent increase in capital market distortions is related to government policies that encourage investments in the state sector at the expense of investments in the more productive non-state sector.     

金融发展与中国的经济增长——从储蓄动员型向市场配置的消费型经济转变

隐形税收机制瓦解后,储蓄动员型的金融发展模式取代了财政投资的主导地位,通过金融支持政策为公有经济部门融资,支撑了经济的高速增长。然而,随着市场约束机制的变化,金融支持政策的收益逐渐下降,成本却在递增。本文认为储蓄动员型的金融支持政策在一定阶段促进了经济的发展,但是也伴随着一系列经济发展的成本,比如降低了资本配置效率,过度投资产生的宏观经济成本和经济持续增长的外部风险加大等。因此,中国金融体制应深化改革,提高金融体系的资本配置效率,促进技术进步和生产效率的改进。同时,通过发展消费信贷和商业保险,减少信贷约束和不确定性,推动消费型经济的增长。     

财政政策的供给效应与经济发展

本文分析了发展中国家公共投资对私人资本积累的动态响应。针对公共资本的拥挤性特征 ,同时考虑财政投资可能引起的风险。在不考虑公共投资风险的分权经济中 ,由于公共资本和私人资本都处于短缺状态 ,企业争夺拥挤性公共资本而扩张私人资本的投资行为虽然使经济超常增长 ,但是存在过度投资和过度拥挤。在集中优化模型中 ,如果考虑到公共投资的风险 ,政府通过税收方式弥补公共投资风险 ,同时将企业投资产生的拥挤效应内部化 ,就能消除企业的过度投资和过度拥挤现象 ,使经济保持合理持续的增长。对中国这样的发展中国家 ,需要重视财政的供给效应 ,在经济起飞初期保证一定数量的政府资本性支出是必要的 ,但随着经济的不断发展和政府资本性支出累积的风险增加 ,财政转型十分必要。

Equilibrium dynamics in discrete-time endogenous growth models with social constant returns

The existing literature establishes possibilities of local determinacy and dynamic indeterminacy in continuous-time two-sector models of endogenous growth with social constant returns. The necessary and sufficient condition for local determinacy is that the factor intensity rankings of the two sectors are consistent in the private/physical and social/value sense. The necessary and sufficient condition for dynamic indeterminacy is that the final (consumable) good sector is human (pure) capital intensive in the private sense but physical (consumable) capital intensive in the social sense. This paper re-examines the dynamic properties in a discrete-time endogenous growth framework and finds that conventional propositions obtained in continuous time need not be valid. It is shown that the established necessary and sufficient conditions on factor intensity rankings for local determinacy and dynamic indeterminacy are neither sufficient nor necessary, as the magnitudes of time preference and capital depreciation rates both play essential roles. We have benefitted from discussion with Robert Becker, Eric Bond, Michael Kaganovich, Karl Shell and participants of the Midwest Macroeconomic Conference in Chicago and the Midwest Economic Theory and International Trade Meetings at Indiana University.

On Footloose Industries and Labor Disputes with Endogenous Information Asymmetry

If capital becomes internationally mobile but labor does not, are outcomes of labor disputes tilted in favor of workers or employers? In this paper, we show that the answer depends critically on how the information structure of the dispute changes endogenously with capital mobility, and in addition, whether international investment incentives selectively favor the outflow of capital from the most or the least productive firms. In doing so, this paper brings together three strands of literature that are not often seen together—incentive compatible contracting, wage and unemployment outcomes of labor disputes, and international capital mobility with heterogeneous firms.     

资源配置、产业结构与全要素生产率：基于真实经济周期模型的分析*

本文旨在测算、分析中国经济及各产业部门的全要素生产率和年均增长率、产业结构高度及其合理化程度，再结合其他37个国家的相应数据进行国际比较。本文依据真实经济周期模型推导出全要素生产率的测算方程并构建了测算产业结构高度及其合理化程度的两个指标。本文发现，由三大产业部门全要素生产率水平之间的差异和部门间规模巨大的人力资本转移而形成的“结构效益”，能够合理解释中国经济整体全要素生产率年均增长率较高但三大产业部门却处在较低水平甚至负增长这两个看似矛盾的经济事实。本文从数理逻辑和经验研究两个角度验证了“产出增长率效应”和“结构效益”的存在。本文通过国际比较发现，中国经济产业结构高度及其合理化程度大幅落后于多数高收入国家。
