Wage rigidity and capital mobility in an optimizing model of a small open economy

Summary This paper formulates an optimizing model of a small open economy with a representative (immortal) household, a firm and a government. The asset menu consists of domestic currency, non-traded bonds and traded bonds. There is a risk premium on traded bonds, which leads to deviations from perfect capital mobility and uncovered interest parity. Taxes are lump-sum, so that finance by bonds and by taxation are equivalent. The model allows for current-account and wealth dynamics. The model assumes either purchasing power parity or imperfect substitution between home and foreign goods and either labour market equilibrium, nominal wage rigidity or real wage rigidity. The steady-state effects of a fiscal contraction, a monetary disinflation and an increase in the world interest rate are discussed. The transient effects of these policies are analysed with the aid of a multiple shooting algorithm.We thank Gerard Staarink for implementing the multiple shooting algorithm used in section 4 and we thank Professors M. Fase and J. Pen for their constructive comments on a previous version of this paper.

Estimates of the Open Economy New Keynesian Phillips Curve for Euro Area Countries

This paper extends the existing literature on the open economy New Keynesian Phillips Curve by incorporating three different factors of production, domestic labor and imported as well as domestically produced intermediate goods, into a general model which nests existing closed economy and open economy models. The model is estimated for nine euro area countries and the euro area aggregate. We find that the general specification of our model improves the fit of the New Keynesian Phillips Curve considerably compared to the closed economy specification. The estimates of the structural parameters of the model suggest strong heterogeneity in the degree of price rigidity across euro area counties. Furthermore, we find the degree of price rigidity to be systematically lower in the open economy specification than in the closed economy specification and also lower than in the general specification of our model.

Government budget deficits,nominal andex ante real long-term interest rates in the U.K., 1960:1–1990:2

This paper explores the impact of government budget deficits on the U.K. nominal and ex ante real long-term interest rates over the period from 1960:1 to 1990:2 utilizing an open and closed economy IS-LM model. An open economy IS-LM model indicates that nominal and ex ante real long-term interest rates are affected by the expected rate of inflation, the real money stock, the real government budget deficit, the real government spending, and the real balance of trade.The evidence presented suggests that increases in the U.K. budget deficits do contribute significantly to increases in nominal and ex ante real long-term interest rates. This implies that rising nominal and ex ante real long-term interest rates, as a result of high government budget deficits, would crowd out private investment and deter capital formation and long-term economic growth.     

Nominal rigidity and some new evidence on the New Keynesian theory of the output-inflation tradeoff

This paper develops a series of tests to check whether the New Keynesian nominal rigidity hypothesis on the output-inflation tradeoff withstands new evidence. In so doing, I summarize and evaluate four different estimation methods that have been applied in the literature to address this hypothesis. Both cross-country and over-time variations in the output-inflation tradeoff are checked with the tests that differentiate the effects on the tradeoff that are attributable to nominal rigidity (the New Keynesian argument) from those ascribable to variance in nominal growth (the alternative new classical explanation). I find that in line with the New Keynesian hypothesis, nominal rigidity is an important determinant of the tradeoff. Given less rigid prices in high-inflation environments, changes in nominal demand are transmitted to quicker and larger movements in prices and lead to smaller fluctuations in the real economy. The tradeoff between output and inflation is hence smaller.     

An empirical analysis of the unit labor cost-product price relation in the U.S. economy

This article tests for cointegration between unit labor costs and the level of product prices in four sectors of the U.S. economy: the aggregate business sector, the nonfinancial corporate sector, durable manufacturing, and nondurable manufacturing. A finding of cointegration for most specifications supports the existence of long-run labor market equilibrium for producers and suggests estimation of error-correction models to examine the dynamic relationships. In every sector except nondurable manufacturing, error-correction model estimates indicate there is a mutual feedback relationship between unit labor costs and prices. Controlling for deviations from full employment, oil price shocks, and the Nixon wage and price controls, the results also provide evidence of significant nominal wage indexation in U.S. labor markets. Throughout the economy there appears to exist both effective neoclassical wage and price adjustment mechanisms to maintain labor market equilibrium and short-run rigidities which may contribute to deviations from full employment outcomes.     

Credit policy,real exchange rate volatility and moral hazard

We extend the well-developed theoretical literature on unconventional credit policy from a closed economy to a small open economy. Consistent with the literature, we find that credit policy has positive effects on output and consumption by raising investment demand. In terms of expanding output, it is more effective to extend government credit to banks than to the goods-producing sector because for each unit of credit supplied to banks, banks - through leverage - can supply greater than one unit of intermediation to firms. We find the welfare implications are ambiguous and depend on the type of policy chosen. A policy of providing funds to goods-producing firms tends to be welfare-improving because it dampens the responses of all variables after a negative shock, including the real exchange rate. However, providing government assistance to the banking sector may be a costly policy because it encourages greater risk-taking on part of banks, leading to higher bank leverage. All else equal, this increases the volatility of the economy, raising the variances of consumption and of the real exchange rate, which is welfare-deteriorating. We interpret this as indicative of the problem of moral hazard associated with a policy of providing support to failing banks.     

技术溢出、技术创新和对外贸易——基于一般均衡视角的一个理论分析框架

文章从微观经济主体的最优化行为出发构建模型,分析技术溢出对技术创新等的影响发现:在封闭经济条件下,创新部门对非创新部门技术溢出的变化对实际工资和消费具有正向效应,而对技术创新的影响则取决于产品替代弹性的大小。在开放经济条件下,任一国技术溢出的变化均会对两国的实际工资和消费产生正向效应;外国对本国技术溢出的变化,对两国的技术创新均具有正向效应,一国创新部门对非创新部门技术溢出的变化会对另一国的技术创新具有正向效应,但对其国内技术创新的影响则取决于产品替代弹性的大小;两国经济地位的变化取决于两国技术进步速度对比的变化。     

Openness,Lobbying, and Provision of Infrastructure

Casual empirical evidence suggests that infrastructure provision is higher in economies that are open to world trade. We develop a model of imperfect competition to show that open economies are likely to provide more infrastructure than closed economies. If infrastructure is financed by taxing a producer lobby, the open economy will overprovide while the closed economy will underinvest; an open economy approaches optimal provision when this lobby group is small in size. If financing of infrastructure is done by taxing the whole population, the closed-economy outcome may be preferred relative to that of the open economy.     

Productivity and the Euro-Dollar Real Exchange Rate

This paper analyses how productivity differentials between the United States and the euro area drive the euro-dollar real exchange rate. We derive impulse responses from a two-sector new open economy macro (NOEM) model. These are used as sign restrictions to identify a structural vector autoregression. Our results show that the Balassa–Samuelson effect, through traded sector productivity shocks, is less important in explaining the variation in the euro-dollar exchange rate than are demand and nominal shocks. In particular, productivity can explain part of the appreciation of the dollar in the late 1990s only to the extent that it created a boost to aggregate demand in the United States. JEL no.

Exchange Rate Volatility, Nominal Rigidities, and Persistent Deviations from PPP

It is shown how nominal exchange rate volatility can cause persistent deviations in the real exchange rate. The key to nominal rigidities is a capital market imperfection implying that agents cannot hedge perfectly against consumption risks. As a consequence, nominal changes have real effects by both affecting the ex post real purchasing power of savings and by affecting the ex ante incentives in savings and labor supply. The consequences of exogenous changes in the nominal exchange rate are considered in an OLG version of a two sector small open economy with competitive product and labor markets.J. Japan. Int. Econ.,December 1997,11(4), pp. 584–609. Department of Economics, University of Aarhus, 8000 Aarhus, Denmark.     

Dual labour markets and nominal rigidity

The conventional menu cost framework performs poorly with realisticlabour supply elasticities: the menu costs required for pricerigidity are very high and the welfare consequences of monetarydisturbances are negligible. We show that the presence of duallabour markets greatly improves the performance of the frameworkboth by reducing the minimum effective menu costs and by boostingthe welfare consequences. In addition, the introduction of duallabour markets provides an explanation of procyclical productivityand the shrinking of wage differentials during booms, in linewith stylized facts on business cycles.     

Exchange Rate Pass-through in a Small Open Economy: the Importance of the Distribution Sector

The degree of exchange rate pass-through to domestic goods prices has important implications for monetary policy in small open economies with floating exchange rates. Evidence indicates that pass-through is faster to import prices than to consumer prices. Price setting behaviour in the distribution sector is suggested as one important explanation. If distribution costs and trade margins are important price components of imported consumer goods, adjustment of import prices and consumer prices to exchange rate movements may differ. We present evidence on these issues for Norway by estimating a cointegrated VAR model for the pricing behaviour in the distribution sector, paying particular attention to exchange rate channels likely to operate through trade margins. Embedding this model into a large scale macroeconometric model of the Norwegian economy, which inter alia includes the pricing-to-market hypothesis and price-wage and wage-wage spirals between industries, we find exchange rate pass-through to be quite rapid to import prices and fairly slow to consumer prices. We show the importance of the pricing behaviour in the distribution sector in that trade margins act as cushions to exchange rate fluctuations, thereby delaying pass-through significantly to consumer prices. A forecasting exercise demonstrates that exchange rate pass-through to trade margins has not changed in the wake of the financial crises and the switch to inflation targeting. We also find significant inflationary effects of exchange rate changes even in the short run, an insight important for inflation targeting central banks.     

Inventories and real rigidities in New Keynesian business cycle models

Kryvtsov and Midrigan (2008) study the behavior of inventories in an economy with menu costs, fixed ordering costs and the possibility of stockouts. This paper extends their analysis to a richer setting that is capable of more closely accounting for the dynamics of the US business cycle. We find that the original conclusion survives in this setting: namely, the model requires an elasticity of real marginal cost to output approximately equal to the inverse intertemporal elasticity of substitution in consumption in order to account for the countercyclicality of the aggregate inventory-to-sales ratio in the data.     

A reapraisal of the capital goods sector in Hong Kong: The case for free trade

This paper was provoked by an earlier one by Fransman (1982) in which he examined the functioning of the capital goods sector in Hong Kong and came to the conclusion that it needed special protection by the government to allow it to reap the benefits of externalities essential for increasing its design and production capabilities. Statistical evidence is provided indicating that the capital goods sector as conventionally defined is prospering. Even following Fransman (1982), and equating the capital goods sector with the machine-producing sector, the latest survey of production indicates considerable dynamism. His case for infant industry protection is further weakened by consideration of the nature of the particular industrial structure of Hong Kong and the quality of the social relations that prevail between entrepreneurs. It is argued that the costs of singling out the capital goods sector for special treatment in terms of the impact of the highly competitive export-oriented manufacturing sector are likely to be high, while the theoretical benefits from externalities are liable to be illusory in a small economy.     

Relative price risk in an open economy with fixed and flexible exchange rates

We analyze the choice between fixed and flexible exchange rates in the context of an open economy version of a multimarkets equilibrium model. In contrast to previous analysis, we separate the information and the shock-absorbing aspects of the two regimes. Under a relative price risk criterion, flexible exchange rates are preferable for a relatively open economy, the more so the less stable are domestic output demand and supply conditions. Fixed exchange rates are preferable for a relatively closed economy, especially so if domestic output demand and supply functions are relatively stable, and if the real balance effect in domestic output demand functions is strong.     

The Balassa-Samuelson model with job separations

We incorporate sectoral job separation rates in a small open economy model to examine the Balassa-Samuelson (B-S) effect. Unequal separation rates give rise to compensating wage differentials. We simulate the model for Japan and replicate a feature of its economy that the nontradeables sector has higher wages and a higher separation rate compared to the tradeables sector. With productivity growth in the tradeables sector, labour moves from the tradeables sector to the nontradeables sector if tradeables and nontradeables are complements in consumption. The B-S effect is dampened. With a higher separation rate in the nontradeables sector, higher wages in the nontradeables sector amplifies this labour movement. Nevertheless, unemployment always falls due to a positive income effect. In contrast, the effect of productivity growth in the nontradeables sector is to lower the real exchange rate and raise unemployment.     

Monetary policy under a liquidity trap: Simulation evidence for the euro area

In this paper, we analyze the conduct of monetary policy under a zero nominal interest-rate bound (hereafter ZIB) in a model economy of the euro area, namely that of the Area Wide Model. The aggregate euro-area economy is modeled to have relatively sluggish adjustment properties and a private sector with mainly backward-looking expectations. For a given ZIB benchmark, we consider variations in the monetary-policy reaction function to minimize the macro-economic consequences of such a deflationary regime. We rank the effectiveness of these remedial policies using a number of metrics and relate our results to features and properties of the model economy. J. Japanese Int. Economies 20 (3) (2006) 338–363.     

Estimated Open Economy New Keynesian Phillips Curves for the G7

In this paper we develop an open economy model of firms’ pricing behaviour under imperfect competition. This allows us to introduce various terms of trade effects influencing the firm’s pricing decision, in addition to labour costs which dominate most closed-economy specifications of the New Keynesian Phillips curve (NKPC). Our analysis gives rise to a hybrid open economy NKPC which nests existing closed and open economy specifications adopted in empirical work. We estimate this specification for the G7 economies and find that the US, UK and Canada typically enjoy less inertia in price setting than the European G7 economies and Japan and that these estimates are both plausible and in line with survey evidence. We also find that the proportion of firms which use simple backward-looking rules of thumb in price setting is greater when the frequency of price change is smaller. Finally there is evidence of significant asymmetries in price setting amongst EMU members.

THE ROLE OF THE EXCHANGE RATE IN A NEW KEYNESIAN DSGE MODEL FOR THE SOUTH AFRICAN ECONOMY

We build a small open economy New Keynesian dynamic stochastic general equilibrium model for South Africa similar to Steinbach et al. We abandon their assumption of complete risk sharing with the foreign economy, and introduce country risk shocks to allow deviations from uncovered interest rate parity. These changes allow us to include the exchange rate as an observable variable in the estimation of the model. Using forecast error variance decompositions and historical decompositions, we show that country risk shocks have sizable effects on the South African business cycle. We also explore the optimal monetary policy implications of our model within the context of Taylor rules.     

Greasing the Wheels of Trade: A Profile of the Dutch Transaction Sector***

How many resources does a nation spend on transactions costs to ‘grease the wheels of trade’? To examine this question the Dutch economy is used as a case study. The Netherlands are known as a nation of traders and this image was derived in the seventeenth century from successes in long distance trade, shipping and financial innovations. Despite its historical background the trading sector has never been adequately measured. In this paper, we present a first attempt in measuring and describing the Dutch transaction sector. Measurement by means of occupational data points out that approximately 25% of Dutch workers is employed in transaction jobs, and 29% if one includes transport tasks. We make the case that traditional industrial sector categories overestimate the true transaction character of an economy. Traditional ‘trade’ sectors employed 13% of the workers in 1807 and 39 percent in 1998, but these figures conceal the fact that all organizations employ jobs which have transformation and transaction tasks. A counterfactual exercise suggests that the growth of the transaction sector share in employment over two centuries was not 200% but 42%.
