International Bank Portfolios: Short‐ and Long‐Run Responses to Macroeconomic Conditions

International bank portfolios constitute a large component of international country portfolios. Yet, banks' response to international macroeconomic conditions remains largely unexplored. We use a novel dataset on banks' international portfolios to answer three questions. First, what are the long‐run determinants of banks' international portfolios? Second, how do banks' international portfolios adjust to short‐run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration? We find that, in the long‐run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short‐run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity‐type variables.     

OUTPUT–EMPLOYMENT RELATIONSHIP ACROSS SECTORS: A LONG‐ VERSUS SHORT‐RUN PERSPECTIVE

This paper investigates the nature of the output–employment relationship by using the Turkish quarterly data for the period 1988–2008. Even if we fail to find a long‐run relationship between aggregate output and total employment, there are long‐run relationships for the aggregate output with non‐agricultural employment and sectoral employment levels for seven of nine sectors that we consider. However, a further investigation for the output and employment relationship within a short‐run perspective does not reveal statistically significant relationships for either total employment or non‐agriculture employment, or eight of the nine sectors that we consider. Although there are various long‐run relationships between output and employment, the short‐run links between demand and employment are weak. The various implications of this for the economy and the labour market are discussed. As a result, maintaining high levels of output in the long‐run creating demand is essential for employment generation.     

The technological determinants of long‐run inequality

I explore the effect of skill‐biased technological change and unbiased technological progress on long‐run inequality using a theoretical model in which the supply of skilled and unskilled workers is endogenous. The main assumption of the model is that young agents can finance their education and become skilled workers by borrowing against their future income on an imperfect credit market. I show that whenever the rate of unbiased technological progress is sufficiently high there is no steady‐state inequality, independent of the degree of skill bias. If instead the rate of unbiased technological progress is low, then the long‐run skill premium increases with the technological skill bias. Therefore, similarly to the short run, in the long run higher technological skill bias may cause higher inequality. However, contrary to the short run, in the long run unbiased technological progress is more important than technological skill bias in determining inequality. I also discuss how the efficiency of the educational technology and the degree of financial development affect long‐run inequality.     

Trade and Investment Linkages and Stock Market Long‐Run Relationship

This paper aims to examine whether the intensity of trade and investment linkages among the countries matter for their stock market long‐run relationship. To achieve this, we classify Australia's bilateral trade and investment partners into major, medium and minor. Empirical findings of an asymmetric generalised dynamic conditional correlation generalised autoregressive conditional heteroskedasticity model show that correlations are time varying and increased significantly during the global financial crisis (GFC). Results of multivariate cointegration test confirm the long‐run equilibrium relationship between the stock markets of Australia and its major partners in the pre‐GFC and during GFC. Based on the full‐sample results, it indicates that the GFC has segmented the stock markets from the long‐run equilibrium relationship. Granger non‐causality test results on full sample show that Australian stock market causes only the New Zealand market while the USA, the UK, Germany, Canada, Switzerland and Italy drives the Australian market. Our results therefore suggest that the intensity of bilateral trade and investment linkages among the countries matter for their stock markets' long‐term relationship.     

Informality and Long‐Run Growth

One of the most salient features of developing economies is the existence of a large informal sector. In this paper, we use quantitative theory to study the dynamic implications of informality on wage inequality, human capital accumulation, child labor, and long‐run growth. Our model can generate transitory informality equilibria or informality‐induced poverty traps. Its calibration reveals that the case for the poverty‐trap hypothesis arises: although informality serves to protect low‐skilled workers from extreme poverty in the short run, it prevents income convergence between developed and developing nations in the long run. Then we examine the effectiveness of different development policies to exit the poverty trap. Our numerical experiments show that using means‐tested education subsidies is the most cost‐effective single policy option. However, for longer time horizons, or as the economy gets closer to the poverty trap threshold, combining means‐tested education and wage subsidies is even more effective.     

The Displacement Effect of Labour‐Market Programs: MONASH Analysis*

A key question concerning labour‐market programs is the extent to which they generate jobs for their target group at the expense of others. This effect is measured by displacement percentages. We describe a version of the MONASH model designed to quantify the effects of labour‐market programs. Our simulation results suggest that: (i) labour‐market programs can generate significant long‐run increases in employment; (ii) displacement percentages depend on how a labour‐market program affects the income trade‐off faced by target and non‐target groups between work and non‐work; and (iii) displacement percentages are larger in the short run than in the long run.     

Long‐run Specialization*

Constructing a dynamic Heckscher–Ohlin model, we examine long‐run specialization patterns in the presence of international technological differences. Even a slight difference in technology causes at least one country to specialize. Either the case of perfect specialization in both countries or the case of perfect specialization in one country and imperfect specialization in the other occurs, depending on the subjective discount rate, relative preference for two commodities, labor endowments, and technological conditions. A necessary and sufficient condition for each case to hold is provided. Structural differences between the Ricardian model and ours are also emphasized.     

ON THE OUTPUT EFFECTS OF BARRIERS TO TRADE*

We study the macroeconomic effects of international trade policy by integrating a Hecksher–Ohlin trade model into an optimal‐growth framework. The model predicts that a more open economy will have higher factor productivity. Furthermore, there is a “selective development trap” to which countries may or may not converge, depending on policy. Income at the development trap falls as trade barriers increase. Hence, cross‐country differences in barriers to trade may help explain the dispersion of per capita income observed across countries. The effects are quantified, and we show that protectionism can explain a relevant fraction of TFP and long‐run income differentials across countries.     

THE J‐CURVE AT THE INDUSTRY LEVEL: EVIDENCE FROM TRADE BETWEEN THE US AND AUSTRALIA*

Previous studies that tested the J‐curve phenomenon for Australia used trade data either between Australia and the rest of the world or between Australia and its trading partners on a bilateral basis. They were unable to find support for the J‐curve in the short run nor any significant relation between the trade balance and the exchange rate in the long run. In this paper we disaggregate the data between Australia and its second largest trading partner, the US, and consider the trade between 108 industries. Using annual data over the 1962–2003 period and bounds testing approach to cointegration and error‐correction modelling, we are able to discover short‐run effects of currency depreciation on the trade balance in 64 industries. The long‐run and positive effects were only evidenced in 35 cases, supporting the J‐curve.     

Rigid labour markets with trade and capital mobility: theory and evidence

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.     

A Factor Endowment Theory of Endogenous Growth and International Trade

This paper presents a dynamic general equilibrium model of multi‐country, two‐good and two‐factor, in which both long‐run growth and international trade patterns are examined. In each country, government expenditure on a public intermediate good plays a crucial role in the realization of persistent growth. It is shown that the long‐run pattern of international trade is determined in a Heckscher‐Ohlin manner.     

International Trade,Technology, and the Wage Gap: Evidence from Granger‐causality Tests*

In this paper, we propose an alternative approach under which to examine the source of the increased wage gap between skilled and unskilled workers in US manufacturing. Rather than imposing the assumptions inherent in a given structural form, we posit a long‐run equilibrium relationship between international trade, technology, and the wage premium using a vector error‐correction model. We first test for the existence of a long‐run relationship using cointegration tests. If a cointegrating relationship is found, we then conduct tests on the direction of the long‐run relationship and of Granger causality. We apply our approach to each two‐digit and four‐digit SIC industry and find evidence in support of international trade being an important source of the wage gap. Our results suggest that it is premature to dismiss international trade as a possible suspect behind the rising wage premium.     

中国对外贸易失衡的影响因素*——基于贸易增加值（TiVA）测算数据的实证分析

中国持续对外贸易顺差引起了学者们的广泛关注。然而现有文献大都基于传统贸易统计方法，没有考虑全球价值链背景下中间品多次跨越国界的重复计算问题，无法反映中国真实的贸易顺差水平。本文基于WIOD数据库1995-2011年的数据，采用投入产出领域的贸易增加值（TiVA）方法，测算出中国与38个贸易伙伴之间的增加值贸易顺差，并对其影响因素进行了实证分析。研究发现，中国加入WTO之前人民币汇率升值对贸易顺差的影响较小而且不显著，而加入WTO之后，人民币汇率升值可以有效降低中国的贸易顺差。在华FDI总额对贸易顺差的影响呈现出相似的特点，即加入WTO之前，总体FDI不显著，加入之后影响显著。FDI来源地区分析显示，美国和亚洲四小龙在中国内地FDI增加可以显著提升中国内地的贸易顺差，而日本和德国在华FDI则会降低中国内地的贸易顺差。     

HISTORY‐DEPENDENT PATHS AND TRADE GAINS IN A SMALL OPEN ECONOMY WITH A PUBLIC INTERMEDIATE GOOD*

This study reexamines McMillan's (International Economic Review 19 (1978), 665–78) analysis of a dynamic small open economy with a public intermediate good. Concerning the trade patterns of the open economy, we find results that were overlooked in McMillan's analysis. Among others, if labor endowment is of intermediate size, there are two saddle‐point steady states, and the initial stock of the public good determines the long‐run trade pattern. We also add a gains‐from‐trade analysis to McMillan's model and demonstrate that if the economy has a comparative advantage in a good with productivity less sensitive to the public intermediate good, the economy may lose from trade at the steady state.     

LONG‐RUN VERSUS SHORT‐RUN PERSPECTIVES ON CONSUMER SCHEDULING: EVIDENCE FROM A REVEALED‐PREFERENCE EXPERIMENT AMONG PEAK‐HOUR ROAD COMMUTERS

Earlier studies on scheduling behavior have mostly ignored that consumers have more flexibility to adjust their schedule in the long run than in the short run. We introduce the distinction between long‐run choices of travel routines and short‐run choices of departure times, using data from a real‐life peak avoidance experiment. We find that participants value travel time higher in the long‐run context, supposedly because changes in travel time can be exploited better through the adjustment of routines. Schedule delays are valued higher in the short run, reflecting that scheduling restrictions are typically more binding in the short run.     

Trade and Global Pollution in Dynamic Oligopoly with Corporate Environmentalism

This paper examines the effects of international trade in the presence of dynamic oligopolistic competition where the stock of global pollution has a negative welfare effect and the oligopolists' objectives may include society's pollution damage as well as private profits. In a symmetric case where the number of firms, emission coefficient, and firms' environmental consciousness are the same in two countries, an opening of trade unambiguously improves each country's welfare in the short run. In the long run, however, trade increases the stock of global pollution and hence, whether opening of trade is beneficial depends on the parameters of the economy. If there are asymmetries between countries, the short‐run gains from trade in both countries are not necessarily guaranteed, because trade liberalization may increase output in one country and reduce it in the other. Moreover, free trade may result in lower pollution stock than under autarky.     

Financial development and economic growth: long‐run equilibrium and transitional dynamics

We analyze the impact of financial development on economic growth. Differently from previous studies that focus mainly on balanced growth path outcomes, we also analyze the transitional dynamics of our model economy by using a finance‐extended Uzawa–Lucas framework where financial intermediation affects both human and physical capital accumulation. We show that, under certain rather general conditions, economic growth may turn out to be non‐monotonically related to financial development (as suggested by the most recent empirical evidence) and that too much finance may be detrimental to growth. We also show that the degree of financial development may affect the speed of convergence, which suggests that finance may play a crucial role in determining the length of the recovery process associated with exogenous shocks. Moreover, in a special case of the model, we observe that, under a realistic set of parameters, social welfare decreases with financial development, meaning that even when finance positively affects economic growth the short‐term costs associated with financial activities more than compensate their long‐run benefits.     

Mean Reversion of Short‐run Interest Rates in Emerging Countries*

In this paper we examine the stochastic behavior of short‐run interest rates in several emerging countries using fractional integration techniques. We allow for a much richer flexibility in the dynamic behavior of the series than the classical representations based on I(0) or I(1) processes. It appears that for Singapore and Thailand nominal interest rates are mean‐reverting, whereas for Mexico, Malaysia, the Philippines, and Korea, the presence of a unit‐root test depends on the assumptions regarding the residuals’ autocorrelation. The results also suggest that uncovered interest parity (UIP) can only hold for two emerging countries. For the other countries, the stabilization policies in the aftermath of the currency crises have led to the rejection of the UIP hypothesis.     

出口市场多元化的经济增长长、短期效应——基于协整和误差修正模型的实证分析

"市场多元化战略"是我国较早提出的外贸战略.虽然短期内出口市场多元化会阻碍经济增长,但长期内对我国经济增长具有促进作用.因此,要保持我国出口收入的稳定增长,就必须继续推行并不断完善出口市场多元化战略.     

An Eaton–Kortum model of trade and growth

We combine a multi‐country, continuum‐good Ricardian model of Eaton and Kortum (2002) with a multi‐country AK model of Acemoglu and Ventura (2002) to examine how trade liberalization affects countries' growth rates and extensive margins of trade over time. Focusing on the three‐country case, we obtain three main results. First, a permanent fall in any trade cost raises the balanced growth rate. Second, trade liberalization increases the liberalizing countries' long‐run fractions of exported varieties to all destinations. Third, the long‐run effects of trade liberalization are different from its short‐run effects, which can reverse the welfare implications of the static Eaton–Kortum model.
