Summary Macroeconomic inventory theory is heavily dominated by the 30 year old accelerator buffer-stock-model, which has been improved only marginally. Its main hypothesis is that entrepreneurs plan a constant inventory-sales-ratio and react on unforeseen deviations by filling in a fixed part of this gap per period, without regarding either the size of the gap nor the degree of capacity utilisation. This study emphasises the distinction between inventories of purchased goods and inventories of self-produced goods. Physical inventories of purchased goods are planned together with the stock of outstanding orders for these goods (as Mack has shown earlier); inventories of selfproduced goods are planned not autononously but together with production and sales. In the long run one should expect a declining inventory sales ratio, but less than the square root formula would suggest if stochastic considerations are taken into account. In the short run for uncertainty theoretical-reasons the planned inventory sales ratio will swing procyclically with undesired countermovements at the turns.In general therefore inventory planning enforces cyclical developments. Growing inventories of finished goods in the boom are possible only if there is no shortage of finished goods but a shortage of means of production. This however is at least not contrary to our evidence. 相似文献

“Ideas” driven growth: the OECD evidence 总被引:6,自引:1,他引:5

This paper estimates the parameters of the ideas production function crucial to recent ideas-driven growth models. Using U. S. patents granted to residents in OECD countries to generate the stock of commercially used ideas, we provide evidence for two main findings. First, at the level of the production of ideas, we find evidence of increasing returns to scale in the stock of ideas and number of researchers, but marginal decreasing returns in each one of these factors. Second, we provide evidence of the association between ideas growth and economic growth for the OECD as a whole in the long run.JEL Classification:

Abstract. I use a dynamic general equilibrium two‐country optimizing model to analyze the implications of international capital mobility for the short‐run effects of monetary policy in an open economy. The model implies that the substitutability of goods produced in different countries plays a central role for the impact of changes in the degree of international capital mobility on the effects of monetary policy. Paralleling the results of the traditional Mundell–Fleming model, a higher degree of international capital mobility magnifies the short‐run output effects of monetary policy only if the Marshall–Lerner condition, which is linked to the cross‐country substitutability of goods, holds. 相似文献

The paper develops a four sector small open economy model with two traded final good sectors, a public intermediate good producing sector and a nontraded good sector producing varieties of intermediate goods. There are three primary factors: capital, skilled labour and unskilled labour. Industrial sector producing a traded good uses capital, intermediate goods and skilled labour as inputs. Intermediate goods producing sector also uses capital and skilled labour. Public input producing sector and the agricultural sector producing the other traded good use capital and unskilled labour as inputs. It is shown that, if production technologies are the same for the agricultural sector and the public input producing sector and if the scale elasticity of output is very low, then an increase in capital stock (unskilled labour endowment) raises (lowers) the skilled–unskilled wage ratio. However, an increase in skilled labour endowment does not produce any unambiguous effect. On the other hand, an increase in the tax rate on industrial output and/or an increase in the price of the agricultural product, armed with the same set of assumptions, lowers the skilled–unskilled wage ratio. 相似文献

Abstract. The present paper uses a dynamic open-economy model with wage indexation to examine the impact of tourism on employment and welfare. Both short-run and long-run situations are analysed. It is well known that tourism converts non-traded goods into tradable goods. An increase in the demand for a non-traded good raises its relative price, which results in an expansion of the non-traded sector at the expense of the traded goods sector. This output shift raises labour employment in the short run. However, in the long run, the higher relative price leads to higher wages, resulting in a negative impact on labour employment. If the output effect is dominant, the expansion in tourism raises employment and welfare. However, under realistic conditions tourism may lower both labour employment and welfare due to rising costs. These results are demonstrated by simulating a dynamic model for the case of Hong Kong. 相似文献

Abstract Is the relative price of investment goods a good proxy for investment specific technology? We model this relative price in a flexible price international economy with two fundamental shocks, namely, the total factor productivity (TFP) shock and the investment‐specific technology (IST) shock. We show that the one‐to‐one correspondence between the IST shock and the relative price of investment goods breaks down in an international economy because of the short‐run correlation between the terms of trade and the relative price of investment goods. The data congruent negative correlation between the investment rate and the relative price of investment goods thus does not necessarily reflect decline in investment frictions (rise in IST), as suggested by many studies. A calibration experiment with the US data demonstrates that such an inverse relation between rate of investment and the relative price of investment goods basically reflects the positive effect of TFP on the terms of trade for a broad range of economies where the home bias in consumption exceeds investment and there is a sizable adjustment cost of investment. 相似文献

Existing studies have demonstrated the necessities of formal institutions and negativity of cultural distance in international investments. Surprisingly, China’s exponential increase of cross-border mergers and acquisitions (M&As) and its low-quality institutions and distinct cultural norms contradict these studies. This paper aims to tackle this puzzle by examining the role of cultural imports in cross-border M&As. Our empirical evidence suggests that the trade of cultural goods significantly increases the volume and realized economic gains of M&As from importing to exporting countries. Our results are robust to alternative measures and an instrumental variable approach. On exploring potential channels, we find that imported cultural goods could drive cultural convergence between countries and also mitigate the adverse effect of cultural distance on merger outcomes. We further show that cultural imports could help firms in overcoming contractual barriers at target countries. This paper provides practical implications for cross-border investments in the current world with intensified cultural conflicts. 相似文献

This study analyzes the interrelationship between goods and services in production and trade using the most recent input–output tables for all OECD countries. It first describes the role of services in production and trade in goods. Next, it proposes two models for analyzing the impact of services trade liberalization on industrial structure. The first captures the role of trade in tasks when countries have different technology i) in production of services; and ii) in organizing production. The latter has to the author's knowledge not been analyzed in the trade literature before. Countries with superior organizational technology (e.g. Japan) will strengthen their comparative advantage in manufacturing following trade liberalization in services. The second model explores the interrelationship between intermediate goods and services i) when they are substitutes; and ii) when they are complements. In both models the gains from trade liberalization is non-linear in trade costs. Going the last mile of liberalization has a much larger impact than taking the first steps. 相似文献

Abstract We develop a multi‐country model with imperfect labour markets to study the effect of labour market frictions on bilateral trade flows. We use a framework that allows for goods trade and capital mobility and show that labour market imperfections exert opposite effects in the absence of capital mobility (the short run) and its presence (the long run), respectively. In the short run, a higher degree of labour market rigidity decreases the value of total trade, but increases the share of intra‐industry trade for a country that is larger than its trading partner. The reverse effects are observed when capital is allowed to cross country borders. Using data on unemployment and income distribution for 23 OECD countries, we compute the central parameter in our theoretical model that describes the degree of labour market rigidity. We use this new empirical concept to provide evidence for our theoretical findings by means of reduced‐form regressions as well as simulation results of a calibrated general equilibrium model. 相似文献

This paper provides a tractable analytical framework to study intertemporal equilibria between non-competitive supply and
dynamic demand for non-durable goods. The basic hypothesis is that consumers enjoy utility from particular services rather
than from commodities. Consumption of the non-durable good follows a dynamic pattern, because it depends on the stock of durables
and energy demand provides the prototypical example, e.g., mobility, thermal comfort, etc. are the output of a combination
of durable and non-durable goods. Indeed, turmoils in energy markets are to a great deal due to short run inflexibility and
this gives this theoretical paper a topical flavour. The outcomes differ substantially across the strategic setups while differences
in expectations (myopic versus rational) matter only transiently but not in the long run.

Fisher hypothesis postulates positive relation between stock return and inflation; however early studies document negative relationship between the two and they conclude that stock cannot be used as a hedge against inflation. In this paper we explore long‐run nonlinear relationship between stock price and goods price. Our sample consists of 19 OECD countries; all or some of these countries have been studied before with the findings of linear cointegration between the stock index and goods price index. Based on unit root tests and linear cointegration test, we apply threshold cointegration tests, Autoregressive Distributed Lag (ARDL) cointegration test and panel VAR method. With all these econometric methods we arrive at heterogeneous findings as follows: two countries have linear cointegration, five countries have threshold cointegration, nine countries do not have any cointegration and finally two countries provide inconclusive results. Estimates of Fisher coefficient provided by linear and nonlinear cointegration methods, which range between 1.27 and 1.86, are consistent with previous studies. Impulse response analysis from panel VAR for countries having no cointegrating relation shows that shock to inflation produces negative response in stock return, which supports findings of earlier studies. 相似文献

We examine the hypothesis that banking crises have real effects on developing economies by reducing imports of capital goods. We test this hypothesis by estimating a model for the determinants of imports of capital goods by a panel of developing economies during 1961 to 2010. Our results suggest that not only do banking crises have statistically significant and economically important effects on imports of capital goods, but these effects increase the longer a banking crisis lasts. Imports of capital goods are a critical component of the capital stock and the production process in developing economies and, thus, our results highlight one important channel through which banking crises may hamper the growth prospects of these economies. 相似文献

How remote is the offshoring threat? 总被引:1,自引:0,他引:1
Advances in communication technology make it possible for workers in India to supply business services to head offices located anywhere. This has the potential to put high-wage workers in direct competition with much lower paid Indian workers. Service trade, however, like goods trade, is subject to strong distance effects, implying that the remote supply of services remains limited. We investigate this proposition by deriving a gravity-like equation for service trade and estimating it for a large sample of countries and different categories of service trade. We find that distance costs are high but are declining over time. Our estimates suggest that delivery costs create a significant advantage for local workers relative to competing workers in distant countries. 相似文献

In this paper, a model with heterogeneous consumption goods is presented. Consumers are assumed to choose between two different consumption goods, characterized by a different impact on the environment. This implies that, in a decentralized economy, government can sustain the social optimum by setting two Pigouvian taxes: one on production as a whole and the other on dirty consumption acting as an incentive in favour of clean consumption. In accordance with the previous literature, a trade-off between a clean environment and economic activity evolves. However, this trade-off is now mitigated by the additional taxation on polluting consumption which allows the control of pollution stock evolution through the substitution between clean and dirty commodities. 相似文献

Estimates of capital stock normally equate different models of capital goods by their production costs at a base date (a concept known as method 1 or K ), not by their current marginal products (method 3, or J ). Some economists advocate that, instead, different models be equated by the base-date costs of providing characteristics of the goods, not of the goods themselves. The characteristics selected have, however, excluded the amounts of other inputs used in the production to which the good is devoted. Hence the method does not equate capital goods by their marginal products but instead by the gross products of the capital goods together with various amounts of associated inputs. Gordon recognizes this defect and believes he has remedied it empirically, but the steps he takes are too slight to support this view. It remains impractical to construct estimates that equate goods by their marginal products. 相似文献

This paper examines the long‐run impacts of selective (or sector‐specific) commodity, payroll, and profit taxes in a two‐sector endogenous growth model with sector‐specific production externalities, in which one sector produces consumption goods and the other produces investment goods. The novelty of the model is that it allows not only for endogenous labour supply but also for the intersectoral allocation of resources, which may together lead to indeterminacy. We analytically show that the stability properties of the long‐run equilibrium critically affect the long‐run effects of these selective taxes, which may reverse the standard results of the growth effects of distortionary taxes. 相似文献

Expenditure reductions played a key role in many small open economies during fiscal consolidation, with large declines in public investment. This led to a reduction in public capital stock and affected the competitiveness of these economies. After the sovereign debt crisis, the governments that consider increasing investment to replenish the public capital stock have limited fiscal space and have to avoid external imbalances. We show that using budget-neutral investment spending can generate long-term benefits of higher public capital stock while at the same time limiting negative consequences for the public finances and the trade balance. The best way of financing government investment, which preserves fiscal and trade balances, and increases welfare, is by reducing other government spending. The second-best is financing investment with value-added tax. Financing with debt worsens fiscal and trade balances, while using distortionary labour taxes reduces labour supply, increases wage costs and worsens the trade deficit in the short run. 相似文献

Asymmetry Effects of Exchange Rate Changes on Domestic Production: Evidence from Nonlinear ARDL Approach

Currency depreciation is said to have positive or negative effects on domestic production. Previous studies that tried to address this issue using Australian data have been inconclusive at best but mostly showed no effects. One common feature of all studies is that they have assumed that the effects of exchange rate changes are symmetric. In this paper, we use the concept of partial sum and separate appreciations from depreciations to test whether the effects are symmetric or asymmetric. Application of the nonlinear ARDL approach of Shin et al. (2014) reveals that indeed the effects of changes in the real effective exchange rate of the Australian dollar are asymmetric in the short run as well as in the long run. While in the short run both appreciations and depreciations affect Australian domestic production, only effects of appreciation last into the long run, a unique finding. 相似文献

The implications of the division of labor, capital, and technology for economic growth have long been a fundamental issue in development economics. This paper employs the bounds testing approach to cointegration to examine the relationship between the division of labor, capital accumulation, communication technology, and economic growth for China over the period 1952–99. We find that in the long run, capital stock and the division of labor both have statistically significant positive effects on growth, while in the short run the effects are not significantly positive. Telecommunication technology, rather surprisingly, has a statistically insignificant impact on growth both in the long run and in the short run. Our findings indicate that there exists a long run equilibrium relationship between capital and the division of labor on the one hand, and economic growth on the other, thereby lending support to the division of labor theory of growth. 相似文献

This paper employs a 55 sector small open economy computable general equilibrium model of the Kenyan economy to assess the impact of the liberalization of regulatory barriers against foreign and domestic business service providers in Kenya. The model incorporates foreign direct investment in business services and productivity effects in imperfectly competitive goods and services markets endogenously, through a Dixit–Stiglitz framework. The ad valorem equivalent of barriers to foreign direct investment have been estimated based on detailed questionnaires completed by specialists in Kenya. We estimate very substantial gains to Kenya from regulatory liberalization in business services, and additional gains from uniform tariffs. The estimated gains increase to 50% of consumption in the long run steady state model, where the impact on the accumulation of capital from an improvement in the productivity of capital is taken into account. Decomposition exercises reveal that the largest gains to Kenya will derive from liberalization of costly regulatory barriers that are non-discriminatory in their impacts between Kenyan and multinational service providers. 相似文献
