Barriers to immigration and the dynamics of emigration

In a dynamic model of emigration and return migration I examine the role of migration costs in the process of capital accumulation of the source country. Every migration attempt reduces the amount of savings available for capital accumulation. It contributes, however, to an increase in the per-capita capital stock of the source country if the migrants leave some of their capital behind or decide to return and repatriate accumulated savings. The interaction among these flows governs the evolution of the economy’s capital stock and factor rewards, which in turn affects the decisions to emigrate and return migrate. Both the quantitative and qualitative effects of host-country policies and other disturbances on the key macroeconomic variables of the source country are found to depend on the level of migration costs.     

Reexamining the interaction between innovation and capital accumulation

In endogenous growth models with innovation and capital accumulation Arnold [J. Macroeconomics 20 (1998) 189] and Blackburn et al. [J. Macroeconomics 22 (2000) 81] show that long-run growth of per capita income is independent of innovation activities; it is solely determined by preferences and the human capital accumulation technology. As a result, government policies do not affect long-run growth. This paper develops an endogenous growth model with innovation and (physical and human) capital accumulation to show that long-run growth depends on both innovation and capital accumulation technologies as well as on preferences and that government taxes and subsidies can have effects on the long-run growth rate.     

The Great Depression in Canada and the United States: A Neoclassical Perspective

Canada suffered a major depression from 1929 to 1939. In terms of output it was similar to the Great Depression in the United States. However, total factor productivity (TFP) in Canada did not recover relative to trend, while in the United States TFP had recovered by 1937. We find that the neoclassical growth model, with TFP treated as exogenous, can account for over half of the decline in output relative to trend in Canada. In contrast, we find that conventional explanations for the Great Depression—monetary shocks, terms of trade shocks, and labor market and competition policies—do not work for Canada.

Selective immigration policies, human capital accumulation and migration duration in infinite horizon

An increasing literature fosters selective immigration policies as a tool to increase human capital in both source and destination countries. These policies are supposed to prompt incentives to education, and–if selection is sufficiently severe–to increase the human capital stock in source countries. Nonetheless, when compared to open migration, selective policies make returns to education uncertain, and they may harm incentives to invest in human capital. As a consequence, they may reduce the human capital stock even though selection is “severe”. Moreover, when repeated migration is possible, they backfire on migration duration. We obtain our results in an infinite-horizon model that, unlike the current literature, places no restriction on the number of possible migration spells and allows for the possibility of a forced emigration.     

Inflation and capital accumulation in an OLG model with money in the production function

This article analyses the consequences of the money supply growth rate on capital intensity and economic growth in an overlapping-generations model with real balances entering the production function. Within this theoretical framework, anticipated inflation generates an ambiguous effect on capital–labour ratio, because two forces work simultaneously in opposite directions: one driving towards a pure Tobin effect (due to the OLG demographic structure of the economy) and the other pushing down the capital stock (due to the productive role of real balances). Despite the unclear effects exerted on capital intensity, higher monetary growth rates unambiguously reduce real money demand, consumption, total wealth and welfare.     

Bank structure, capital accumulation and growth: a simple macroeconomic model

Summary. This paper analyzes the equilibrium growth paths of two economies that are identical in all respects, except for the organization of their financial systems: in particular, one has a competitive banking system and the other has a monopolistic banking system. In addition, the sources of inefficiencies, as a result of monopoly banking, and their relationship to the existence of credit rationing are explored. Monopoly in banking tends to depress the equilibrium law of motion for the capital stock for either of two reasons. When credit rationing exists, monopoly banks ration credit more heavily than competitive banks. When credit is not rationed, the existence of monopoly banking leads to excessive monitoring of credit financed investment. Both of these have adverse consequences for capital accumulation. In addition, monopoly banking is more likely to lead to credit rationing than is competitive banking. Finally, the scope for development trap phenomena to arise is considered under both a competitive and a monopolistic banking system.

Austrian persistence? Capital-based business cycle theory and the dynamics of investment spending

Survey data are used to investigate the very long spending lags estimated in neoclassical studies of investment expenditures. Neoclassical investment theory has trouble explaining the length of these lags. By recognizing the Austrian concept of the capital structure and applying it to the problem, the present paper explains the length of these lags as proceeding from interactions between types of capital. Austrian arguments stemming from Austrian business-cycle theory seem to be needed to explain these lags. JEL Code E3, E4, C1     

Capital accumulation and real exchange rate behavior in a small open economy with credit market frictions

Summary. We consider the nature of the relationship between the real exchange rate and capital formation. We present a model of a small open economy that produces and consumes two goods, one tradable and one not. Domestic residents can borrow and lend abroad, and costly state verification (CSV) is a source of frictions in domestic credit markets. The real exchange rate matters for capital accumulation because it affects the␣potential for investors to provide internal finance, which mitigates the CSV problem. We demonstrate that the real exchange rate must monotonically approach its steady state level. However, capital accumulation need not be monotonic and real exchange rate appreciation can be associated with either a rising or a falling capital stock. The relationship between world financial market conditions and the real exchange rate is also investigated. Received: October 3, 1997; revised version: October 23, 1997     

Housing and the Great Depression

This article considers the structural stability of the relationship between the real housing price and real GDP per capita for an annual sample that includes the Great Depression. We test for structural change in parameter values using a sample of annual US data from 1890 to 1952. The article examines the long-run and short-run dynamic relationships between the real housing price and real GDP per capita to determine whether these relationships experienced structural change over the sample period. We find that temporal Granger causality exists between these two variables only for subsamples that include the Great Depression. For the other subsample periods as well as for the entire sample period, no relationship exists between these variables.     

20世纪30年代大萧条中的中国宏观经济

本文对20世纪30年代世界经济大萧条中的中国经济进行历史回顾和经济理论分析,并与西方主要金本位国家进行比较,力图还原历史的本来面目。本文的研究发现,有两个因素在大萧条时期的中国经济中起到了重要作用,一个是银本位,一个是竞争性的银行体系。银本位使中国经济萧条的进程迥然不同于西方金本位国家;不同于西方国家主要通过财政政策度过大萧条,中国由于特殊的银行体系,货币供给始终没有减少,银行危机也没有普遍发生,这是中国经济在整个大萧条中表现较好的一个重要原因。     

Capital accumulation during the transition from plan to market1

This paper focuses on the process of capital accumulation and the forces that drive it in the countries undergoing the transition from plan to market. The methodological framework for analyzing the determinants of aggregate business investment draws on the neoclassical accelerator model, extending it to reflect some of the specificities of the transition environment. The model is estimated on data for the economies in Central and Eastern Europe (CEE) and the Commonwealth of Independent States (CIS). The results highlight the role of some key drivers of capital accumulation in an economy in transition, in particular, the relatively significant accelerator response to output, the importance of adjustment effects and financing constraints and the relatively minor role of the cost of capital.     

Human capital accumulation in an open labour market: Ireland in the 1990s

Large-scale investment in education in Ireland began in 1967 and has led to a dramatic increase in the relative supply of skilled labour over the past four decades. Furthermore the supply of labour in Ireland is traditionally highly elastic through migration, which in the 1990s was predominantly high-skilled. This combination of rising education levels and an open labour market meant that employment and incomes rose rapidly in the 1990s, while Ireland still maintained a strong competitive position in terms of relative labour costs.In this paper we develop a new macro-economic framework to formally analyse these mechanisms. We estimate a small structural model of the Irish labour market, separately identifying high-skilled and low-skilled labour. We find that this model captures key characteristics of the Irish labour market in the 1990s.     

Capital accumulation through studying abroad and return migration

This paper examines the interplays among studying abroad, return migration and capital accumulation, in a dynamic general equilibrium model featuring heterogeneous ability. Households invest in education and make two migration decisions: whether to study abroad and subsequently whether to return home. The model predicts that the highest, middle and lowest-ability people choose respectively permanent migration, return migration and no migration. More interestingly, we find a novel migration cycle: returnees bring back learned-knowledge and over time, capital accumulates, attracting more return migration. Further, the usual “brain drain” in the literature can be turned into “brain gain”, by providing a subsidy to studying abroad and returning home.     

Chinese lessons: state-owned enterprises and the regulation of foreign investment in Canada

A recent influx of Asian investment is changing the character of the Canadian oil and gas industry and reviving old debates on the regulation of foreign investment. Particular attention has been placed on investment by state-owned enterprises (SOEs), driven in part by public suspicion about investment from China, which has been the largest source of SOE capital flows to Canada. Recent amendments to the Investment Canada Act have made SOE investment more difficult and have raised questions about the country’s attractiveness as an investment destination. This paper makes the case for non-discrimination of SOEs in the investment review process. In the context of a policy framework that is fundamentally supportive of inward foreign direct investment (FDI), the Canadian government does not require a set of redundant measures to protect against the relatively low risk of undesirable investment.     

Exchange rate volatility and United Kingdom trade: evidence from Canada,Japan and New Zealand

This paper investigates the influence of exchange rate volatility on the real imports of the United Kingdom from Canada, Japan and New Zealand during the period 1980–2003. The Johansen multivariate cointegration method and the constrained error correction (general-to-specific) method are applied to study the relationship between real imports and its determinants (including exchange rate volatility). Conditional variance from the GARCH(1,1) model is applied as exchange rate volatility. Both nominal and real exchange rates are employed in the empirical study. Results indicate a significant effect of the exchange rate volatility on real imports. These exchange rate volatility effects are mostly positive. The author thanks an anonymous referee, the editor and Myles Wallace for several useful comments and suggestions. Any remaining errors and omissions are the author’s responsibility alone.     

The joint dynamics of inflation, unemployment and interest rate in the United States since 1980

In this paper, by using a combination of long-run and short-run restrictions, we identify a small structural VECM which includes inflation, unemployment and the federal funds rate and study the dynamic interactions at different frequencies among these variables. Our results show that: (a) in accordance with the traditional view of economic fluctuations, aggregate demand shocks and monetary policy shocks push inflation and unemployment in opposite directions in the short run; (b) the permanent supply shock explains the long-run movement of inflation and unemployment. These conclusions are at odds with the prediction of “natural-rate” models but are consistent with the idea of a propagation mechanism which links productivity shocks to inflation and unemployment at medium and low frequencies. Thus, with respect to some recent studies (e.g. Beyer and Farmer, ECB Working Paper 121, 2002, and Ireland, J Monet Econ 44:279–291, 1999), we offer a different interpretation of the low-frequency comovements between inflation and unemployment characterizing the US economy in the last decades.

A prototype model of the foreign exchange market of Canada: Forecasting capital flows and exchange rates

A balance-of-payments structural model of the foreign exchange market of Canada, endogenizing capital flows, the spot and forward exchange rates and the entities of the monetary sector, is developed using quarterly data for 1971–81. The capital flows have been disaggregated into ten categories and the exchange rates of the Canadian dollar have been analysed against five major currencies. While the model does not adhere strictly to purchasing power or interest rate parity, it does recognize them and it also incorporates other economic fundamentals, expectations and risk. Government interventions, although generated endogenously, are quantified implicitly and globally. The model tracks the post-Bretton Woods in-sample experience and generates ex post predictions reasonably well.     

Some Observations on the Great Depression in Germany

Abstract. This paper evaluates the role of preference shocks during the Great Depression in Germany. From Euler equation residuals, I am able to identify a series of contractionary shocks that struck the German economy from 1929 to 1932. I apply the sequence of these taste innovations to a dynamic general-equilibrium model and find that the size and the order of shocks can generate a pattern that can explain the lion's share of the decline in economic activity. The artificial economy also predicts a swift recovery after 1932, thereby questioning any significant effects of Nazi economic policy.     

中国工业增长因素的实证研究

使用参数估计法与隐型变量法估算了1952-2009年中国工业的增长因素。研究发现,1952-2009年我国工业总体上表现为典型的粗放型增长方式,但在不同时期各增长因素的重要性表现出阶段性特征,特别是1996年后,智力要素对产出增长的贡献度第一次超过了初级要素投入的贡献度,成为推动中国工业产出增长的首要因素,表明中国工业的增长方式开始由粗放型向集约型转变。要进一步推动我国工业的集约型增长,需要遏制资本产出弹性的下降趋势,并充分发挥人力资本的作用。
