Maintenance expenditures and indeterminacy under increasing returns to scale

This paper develops a one-sector real business cycle model in which competitive firms allocate resources for the production of goods, investment in new capital and maintenance of existing capital. Firms also choose the utilization rate of existing capital. A higher utilization rate leads to faster capital depreciation, and an increase in maintenance activity has the opposite effect. We show that as the equilibrium ratio of maintenance expenditures to GDP rises, the required degree of increasing returns for local indeterminacy declines over a wide range of parameter combinations. When the model is calibrated to match empirical evidence on the relative size of maintenance and repair activity, we find that local indeterminacy (and belief-driven fluctuations) can occur with a mild and empirically-plausible degree of increasing returns: approximately 1.08.     

Building original series of physical capital stocks for China's economy methodological problems,proposals for solutions and a new database

There are to date no official Chinese statistics relating to capital stocks. This lacking data hinders econometric studies of growth in this country. Series of such stocks are proposed in the literature, but most available empirical work on this topic suffers multiple deficiencies. The purpose of this article is to build the most reliable and longest possible statistical series of capital stocks for China. Our initial capital stocks are calculated on the basis of an output-capital ratio which is less approximate (and lower) than those generally provided. Our investment flows are consistent with the perimeters of the initial stocks. Our investment price indices are strictly tailored to the content of these stocks, and the unit root tests show that all the indices are non-stationary and cointegrated to the order of 2. This means they cannot be substitutes, as supposed in many other studies. Our depreciation rates are estimated by type of capital, under assumptions consistent with age-efficiency and retirement. Investment shares are used to approximate an overall capital structure and to calculate a total depreciation rate. Built from 1952 to 2014, our original series are available to econometricians seeking to conduct new empirical studies on China, over the long run.     

The bilateral J-curve: Turkey versus her 13 trading partners

This study empirically analyses bilateral J-curve dynamics of Turkey with her 13 trading partners using quarterly time series data over the period 1985–2005. Short- and long-run impacts of the depreciation of Turkish lira on the trade balance between Turkey and her 13 trading partners are estimated from the bounds cointegration testing approach and error correction modelling. The empirical results indicate that whilst there is no J-curve effect in the short-run, but in the long-run, the real depreciation of the Turkish lira has positive impact on Turkey's trade balance in couple of countries. The stability of the long-run trade balance equations is also checked through CUSUM and CUSUMSQ stability tests.     

Exchange Rate Regime,Financial Market Bubbles and Long‐term Growth in China: Lessons from Japan

Since 2014, capital inflows into China have turned into capital outflows, reversing the gradual appreciation path of the renminbi against the US dollar into an erratic depreciation path. The paper explains the current capital outflows by comparing China and Japan with respect to the impact of exchange rate expectations on speculative capital flows. It is argued that both in China and Japan, given benign liquidity conditions in the USA, policy‐induced appreciation expectations have generated capital inflows that have contributed to overinvestment and financial market bubbles. The current reversal of capital flows is seen as a signal that the bubble in China has burst. To stabilize growth in China and to discourage speculative capital outflows a fixed exchange rate to the dollar is recommended. Given Japan's experience and given that China's foreign assets remain high, the depreciation pressure on the Chinese renminbi can be expected to abate.     

EFFECTS OF THE REAL EXCHANGE RATE ON OUTPUT AND INFLATION: EVIDENCE FROM TURKEY

This paper assesses the effects of real depreciation on the economic performance of Turkey by considering quarterly data from 1987:I to 2001:III. The empirical evidence suggests that, contrary to classical wisdom, the real depreciations are contractionary, even when external factors like world interest rates, international trade, and capital flows are controlled. Moreover, the results obtained from the analyses indicate that real exchange rate depreciations are inflationary.     

The effect of interruptions and part-time work on women's wage rate: A test of the variable-intensity model

Summary In this article we investigated the effects of interruptions of labour market participation and part-time work on women's gross wage rates, using the variable-intensity model. Women who interrupt their labour market careers suffer not only from depreciation, which effects all workers. Every year they do not participate they also miss experience. Part-time work mitigates the depreciation of human capital compared to a situation of non-participation. The expectation that part-time work — as opposed to full-time work — leads in the long run to a lower wage rate is confirmed.     

An index of growth due to depreciation*

Abstract. While factors such as inflation, technological change and growth often have been discussed in connection with the adequacy of provisions for depreciation under a historical cost model, there is another dimension to the capital maintenance problem and it concerns the multiplier effect of depreciation. When an amount equal to depreciation is reinvested, a firm's productive capacity tends to increase. Reinvestment of depreciation also increases a firm's financial capital if book depreciation is more accelerated than economic depreciation. Based on a model developed by Ijiri (1967), this paper derives an index of this growth due to depreciation. The index estimates a bias in conventional depreciation methods that has been overlooked in the literature on the subject. This bias has implications for inflation accounting because if conventional depreciation methods have a built-in growth bias, adjustments for inflation may be a type of double counting. A second implication mentioned concerns the bias in accounting rates of return. Résumé. Bien que des facteurs tels l'inflation, les changements technologiques et la croissance ont souvent été examinés à propos de la pertinence des provisions pour dépréciation dans le cadre du modèle au coût historique, un autre aspect du problème de préservation du capital subsiste et il concerne l'effet multiplicateur de l'amortissement. Lorsqu'un montant égal à l'amortissement est réinvesti, la capacité d'exploitation de la firme a tendance à s'accroître. Le réinvestissement de l'amortissement fait aussi augmenter le capital de la firme si l'amortissement comptable est plus accéléré que la dépréciation économique. En se basant sur un modèle élaboré par Ijiri (1967), cet article dérive un indice de cette croissance attribuable à l'amortissement. L'indice estime un biais des méthodes traditionnelles, qui a été négligé dans les recherches consacrées au sujet. Ce biais a des implications en comptabilité des effets de l'inflation, car si les méthodes d'amortissement traditionnelles comportent implicitement ce biais de croissance, les redressements relatifs à l'inflation peuvent être assimilés à un double comptage. Une deuxième conséquence est signalée, soit le biais relatif aux taux de rendement comptable.     

New capital estimates for China

Data on physical capital are an indispensable part of economic growth and efficiency studies. In the case of China, economy-wide fixed asset series are usually derived by aggregating gross fixed capital formation (net of depreciation) over time, and sectoral/ownership-specific series by correcting the limited official fixed asset data available. These procedures, to varying degrees, ignore that (i) gross fixed capital formation does not equal investment, (ii) investment does not equal the value of fixed assets newly created through investment, (iii) depreciation is an accounting measure that bears no necessary relation to changes in the production capacity of fixed assets, (iv) official fixed asset data, where available, incorporate significant revaluations in the 1990s, and (v) “net fixed assets” do not measure the contribution of fixed assets to production.This paper derives economy-wide fixed asset values for 1953–2003, correcting for these shortcomings. It uses both the traditional, cumulative approach and a new, so far unexplored method of combining economy-wide depreciation values and an economy-wide depreciation rate to directly yield economy-wide fixed assets. The derived fixed asset time series are evaluated in a comparison with each other as well as with series in the literature, leading to the recommendation of a specific choice of fixed asset time series.     

Government Purchases and the Real Exchange Rate

Recent empirical research documents that an exogenous rise in government purchases in a given country triggers a persistent depreciation of its real exchange rate—which raises an important puzzle, as standard macro models predict an appreciation of the real exchange rate. This paper presents a simple model with limited international risk sharing that can account for the empirical real exchange rate response. When faced with a country-specific rise in government purchases, local households experience a negative wealth effect; they thus work harder, and domestic output increases. Under balanced trade (financial autarky) this supply-side effect is so strong that the terms of trade worsen, and the real exchange rate depreciates. In a bonds-only economy, an increase in government purchases triggers a real exchange rate depreciation, if the rise in government purchases is sufficiently persistent and/or labor supply is highly elastic.     

比较优势、贸易结构与资本积累：对Mazumdar假说适用性的检验及其扩展

Mazumdar（1996）的研究认为：当一国为资本品净进口国和消费品净出口国时,资本品的进口将导致资本品价格的下降进而引致折旧率的下降,结合Solow增长模型,折旧率的下降将促使一国投资率的上升并引致资本积累。本文运用中国数据对这一假说检验后认为：该理论只适用于小国贸易模式,对于诸如中国这样的贸易大国,比较优势决定下的贸易结构完全符合Mazumdar条件,但资本品进口和消费品出口并没有对中国资本积累起到促进作用,根本原因在于这样的贸易结构往往提高了资本品一消费品的相对甚至绝对价格,并最终恶化了中国的贸易条件,使得贸易收益并不明显。本文围绕这些这些问题进行了一定层次的论证。     

When should firms invest in old capital?

The present paper analyzes optimal investment policies when the production function depends on capital of various vintages. In such an environment it is natural to ask whether the firm will invest in old-vintage capital at all. Other studies do not tell us when investment in old capital will take place. In the present paper I derive such a condition. Predictably, investment in old capital takes place if the elasticity of substitution between old and new capital is low, and when the depreciation of capital is high. However, other parameters such as the rates of technological progress and depreciation matter as well.     

THE IMPACT OF HIV/AIDS ON ECONOMIC GROWTH IN SUB‐SAHARAN AFRICA1

This study investigates the hypothesis that HIV/AIDS epidemic slows down the pace of economic growth. We examine 41 Sub‐Saharan African countries by using the empirical growth equation in an augmented Solow model in which health capital serves as a determinant of human capital. Econometric analysis is based on panel data and covers the period 1997‐2005. We control for a variety of factors possibly correlated with HIV prevalence that might also influence economic growth. As a key result we prove that the epidemic has a significant negative effect on the growth rate of per capita GDP in Sub‐Saharan Africa.     

Is the J-Curve Effect Observable for Small North European Economies?

The present study tests for the J-curve for five North European countries—Belgium, Denmark, The Netherlands, Norway, and Sweden—using generalized impulse response functions. The results provide empirical support for the J-curve. Each country has an impulse response function generated from a vector error-correction model that suggests that after a depreciation, there will be a dip in the export-import ratio within the first half-year after the depreciation. The long-run export-import ratio appears to be higher than the low point of this early dip in almost all cases. Also, in most cases, the export-import ratio appears in many periods after the depreciation to be converging from below to a higher long-run equilibrium.     

Debt financing and sharp currency depreciations: wholly versus partially-owned multinational affiliates

This paper provides empirical evidence on two potential costs of shared ownership of German affiliates abroad. First, in periods of currency crises, wholly-owned affiliates, in contrast to partially-owned affiliates, seem to circumvent financial constraints by accessing capital from their parent companies. In terms of differences in performance regarding sales of both types of firms, wholly-owned affiliates have a significantly better sales performance than partially-owned affiliates in periods of crises. This finding contributes to the evidence that FDI helps in mitigating the negative consequences of sharp currency depreciation, and stresses that this effect works especially through capital inflows to wholly-owned affiliates. Second, the debt financing of partially-owned affiliates is less sensitive to the tax rate suggesting that partially-owned affiliates rely less on international debt shifting than wholly-owned affiliates. This indicates that partially-owned affiliates are less flexible to exploit tax efficient strategies.     

人力资本存量贬损研究

长期以来人们热衷于研究人力资本增值在经济增长中的作用,却忽略了人力资本存量贬损。人力资本存量贬损是人力资本的逆态增值或负增值,和人力资本增值一样,也是市场的常态现象。中国经济快速发展、产业结构不断调整催生出的技术性失业和结构性失业,发出了人力资本存量贬损的信号。本文界定人力资本存量贬损的概念,分析其特点,剖析发生贬损的原因,旨在推动个人、企业和政府,及时有效地将社会资源配置到产业结构升级、经济结构转变、技术进步需要的人力资本上。     

THE IMPACT OF EXCHANGE RATE MOVEMENTS ON FOREIGN DIRECT INVESTMENT: MARKET‐ORIENTED VERSUS COST‐ORIENTED

This paper examines the impact of exchange rate movements on foreign direct investment (FDI). We first employ a real options model to show that while the depreciation of a host country's currency tends to stimulate FDI activity of cost‐oriented firms, the depreciation tends to deter FDI activity for market‐oriented firms. With industry panel data on Taiwan's outward FDI into China over the period 1991–2002, our empirical findings indicate that the exchange rate level and its volatility in addition to the relative wage rate have had a significant impact on Taiwanese firms’ outward FDI into China. In general, the empirical results are consistent with the prediction of the theory. Our results reveal that the relationship between exchange rates and FDI is crucially dependent on the motives of the investing firms. Without considering this fact in an empirical model, the testing results might suffer from aggregations bias.     

Role of Endogenous Vintage Specific Depreciation in the Optimal Behavior of Firms

This paper studies the firms' capital accumulation process in a vintage capital model with embodied technological change. We take into account that depreciation is endogenous and in particular associated with vintage specific maintenance expenditure. We prove that maintenance is a local substitute for investment as soon as the marginal cost of maintenance is strictly increasing. We show that maintenance and investment in new capital goods appear as complements with respect to the changes in productivity, cost of maintenance, fixed cost of operation, efficiency of maintenance services and appear as substitutes with respect to the price of new machines. Allowing for investment in old vintages, we determine that investment in old machines appears as a substitute of both investments in new machines and maintenance services. We end up by analyzing the effects of technological progress on optimal plans and prove that a negative anticipation effect can occur even without any market imperfections.     

The Impact of the US Interest Rate Hike on Emerging Market Economies and the Belt and Road Initiative

Since the end of 2015, the US Federal Reserve has raised its benchmark interest rate nine times. This has led to capital outflows and asset depreciation in many emerging market economies. The present paper examines the factors that determine the financial volatility of emerging markets in the face of external shocks. By calculating the capital flows of 30 emerging markets from 1990 to 2018 and conducting panel regression, this paper finds that countries with good infrastructure facilities, a sound banking system and high economic growth have significantly lower cross‐border financial risks. An implication from the empirical analysis is that emerging countries would benefit greatly by actively taking part in the Belt and Road Initiative. The framework of the Belt and Road Initiative allows emerging countries better access to China's massive consumer market to promote trade and long‐term growth. Their quality of infrastructure can be improved through cooperation with China in infrastructure investment. They can also jointly establish a cooperative financial framework to enhance regional financial stability. These strategies will reduce systematic financial risks and counteract the negative impacts of US interest rate hikes.     

FOREIGN DIRECT INVESTMENT IN ZIMBABWE: THE ROLE OF INSTITUTIONAL AND MACROECONOMIC FACTORS

The purpose of our research is to examine the impact of property rights on foreign direct investment (FDI) in Zimbabwe for the period 1964‐2005. While the macroeconomic determinants of FDI have been analysed to a considerable extent in past empirical work, the role of institutional factors such as the protection of property rights and the efficiency of the legal system has been underexplored. Using a multivariate cointegration framework, we use a newly constructed de jure property rights index for Zimbabwe to determine the impact of property rights on FDI. The empirical evidence shows that property rights are consistently an important explanatory variable of FDI in Zimbabwe, even after controlling for periods when there are no significant new foreign capital inflows. Other significant explanatory variables of FDI in Zimbabwe are the real gross domestic product (GDP), capital intensity, the external debt to GDP ratio, political instability as well as the educational levels.     

Nonlinear Capital Flow Tax: Capital Flow Management and Financial Crisis Prevention in China

How to promote capital account liberalization while preventing financial crises is a challenging task for policymakers. This study proposes a nonlinear (progressive) capital flow tax as a solution. We first demonstrate that the collateral requirement of international borrowing can give rise to multiple equilibria and self‐fulfilling financial crises. We then show that the crisis equilibrium characterized by large exchange rate depreciation, capital flight and welfare loss can be eliminated by imposing a nonlinear (progressive) tax scheme on capital outflows with the marginal tax rate increasing with the size of individual capital outflows. The implementation of such a tax scheme in China is also discussed.
