Optimal exchange rate policy for a small oil-exporting country: A dynamic general equilibrium perspective

This paper examines the choice of optimal exchange rate regime for an oil-exporting small open economy using a welfare-based model. The paper extends the standard New Keynesian Small Open Economy model to include three countries: a small oil-exporting country and two large foreign countries. The model also features three sectors: traded, non-traded, and primary-commodity (crude-oil). The sources of uncertainty are random monetary (demand), productivity (real), and real oil price (supply) shocks. Despite the absence of a non-oil traded sector in this primary-commodity economy, the welfare analysis suggests that flexible exchange rate regimes can reduce external shocks and consumption volatility given certain caveats about pricing-schemes. The analysis also suggests that a basket peg is more welfare-improving than a unilateral peg, as higher volatility of the anchor currency reduces consumer welfare.     

Inflationary effects of monetary policies in newly industrialized economies with cross-sectoral labor and capital immobility

This paper studies the effects of monetary policies in newly industrialized economies characterized by extremely low level of labor and capital mobility between urban and rural sectors. Policies are executed in the urban sector which sends waves of adjustments in the rest of the economy. I show that with liquidity constraints and immobility in labor and capital, the sector-specific effects are markedly different from those in a one-sector economy. In particular, they are asymmetric and the rural sector lags behind the urban sector during adjustment process. This explains temporary phases of significantly high inflation with uneven sectoral effects which often accompany major reforms in the banking and monetary institutions of such economies, e.g. in case of India. Finally, as consumption patterns alter in such an economy undergoing structural changes, the sectoral distribution of liquidity is affected inducing dissimilar responses to shocks, both within and between sectors.     

资本账户开放与国际金融冲击的传导——基于DSGE模型的分析

本文在动态随机一般均衡的框架下,建立了一个包括贸易部门和非贸易部门的小型开放经济模型,系统研究和比较资本管制与资本账户开放两种情况下,国外金融冲击、出口需求冲击对中国经济的不同影响和传导机制,并检验资本账户开放情形下应对国际冲击时不同货币政策规则的有效性。结果发现：当资本账户开放时,一国受到国外冲击的波动幅度远大于资本管制的情况;资本管制和资本账户开放对国际金融冲击传导机制的关键差异在于贸易部门与非贸易部门的互动关系,具体表现为劳动力转移的差异;在资本账户开放后,面对不同形式的国际冲击,货币数量型规则和混合型规则均能有效熨平经济波动。     

MONETARY AND FISCAL POLICY EFFICIENCY AND COORDINATION IN A MULTI‐SECTOR OPEN‐ECONOMY GENERAL EQUILIBRIUM MODEL

The paper analyzes monetary and fiscal stabilization and coordination in a multi‐sector stochastic new open economy macroeconomics (NOEM) model. It first aims to assess the capacity of fiscal and monetary policy to reduce or eliminate the negative welfare effects of an unanticipated productivity shock affecting some or all of the sectors in each country. Second, it evaluates the possible gains from international monetary cooperation as well as the impact of active fiscal policy on the welfare performance of monetary policy. The setup also allows for international asymmetry concerning the uncertainty over the shocks. The results show that monetary and fiscal policies are efficient tools of stabilization and under several conditions they can replicate the flexible‐price equilibrium. However, their welfare performance is not necessarily increased when both monetary and fiscal policies react to shocks at the national level. The existence of bilateral gains from monetary cooperation depends on the degree of asymmetry concerning the uncertainty over the shocks.     

The impact of monetary policy on housing market activity: An assessment using sign restrictions

Existing research demonstrates that housing, particularly residential investment, plays an important role in the transmission of monetary policy shocks to the overall economy. With this in mind, this paper investigates the relationship between monetary policy and housing market activity using a relatively new method for identifying monetary shocks. More specifically, a monetary policy shock is identified by explicitly imposing sign restrictions on impulse response vectors. The extra information from sign restrictions is important for new insights regarding the transmission of monetary policy to the housing sector – notably, the results indicate that residential investment is less sensitive to a contractionary shock than standard estimates with recursive restrictions. Given that the response of the housing sector using sign restrictions is smaller than other work using standard identification methods, the work indicates that further research is needed to examine whether other sectors of the economy may be less sensitive to monetary policy than previously thought.     

On the mark(s): Optimum currency areas in Germany

In the wake of unification, the former GDR became a member of the DM monetary zone. We evaluate whether unified Germany satisfies the criteria defining an optimal monetary area. We conclude that the primary criterion, similarity of shocks, is not satisfied even by the western states, a reflection of the importance of sector-specific relative to geographic shocks coupled with different sectoral structures. Extending this argument, we conclude that the correlation of shocks to the eastern states with western states is also likely to be small. A case for monetary unification must, in consequence, be based on political rather than narrowly economic calculations.     

Supply shocks and the interdependence of macroeconomic stability under flexible exchange rates

This paper analyzes the effects of a change in the monetary policy of a large economy on the macroeconomic stability of a small open economy with high dependence on imported intermediate goods. The analysis is carried out using the Taylor framework where the money supply rule is specified by the degree of monetary accommodation of price shocks. A supply shock to the large country is transmitted as both demand and supply shocks to the small country. A shift toward less monetary accommodation by the large country is shown to increase both price and output instability in the small country through the supply side linkage, while it may enhance price or output stability through the demand side linkage. Simulation results for Germany and Japan suggest that the supply side effect on price stability is important and that the effect on output stability depends crucially on the importance of trade in goods between the large country and the country in question.     

Market concentration, macroeconomic uncertainty and monetary policy

This paper studies the effect of market structure and macroeconomic uncertainty on the transmission of monetary policy. We motivate our analysis with a simple model which predicts that: (1) investment and production in more concentrated sectors are more affected by demand shocks and (2) high uncertainty makes investment and production more sensitive to demand shocks. The empirical analysis estimates the effect of monetary shocks on sectoral output for different sectors in the US using a structural vector autoregressive (VAR) approach. The results are generally consistent with the theoretical predictions.     

The cost of capital,asset prices,and the effects of monetary policy

The primary objective of this paper is to study the interaction between monetary policy, asset prices, and the cost of capital. In particular, we explore this issue in a setting where individuals face idiosyncratic risk. Incomplete information also provides a transactions role for money so that monetary policy can be studied. In contrast to standard monetary growth models which focus on the transmission of monetary policy to the demand for capital goods, we incorporate a separate capital goods sector so that the supply response to monetary policy is taken into account. Consequently, in contrast to the standard monetary growth model, monetary policy plays an important role in investment activity through the relative price of capital goods. Moreover, different sources of productivity can affect the degree of risk sharing. Although the optimal money growth rate falls in response to an increase in productivity in either sector of the economy, monetary policy should react more aggressively to the level of productivity in the capital sector.     

Modelling the sectoral allocation of labour in open economy models

Indivisible labour is not the only type of non‐convexity affecting labour supply decisions. Another type of non‐convexity arises in economies with sectors whenever individuals can work in only one sector at a time. I introduce this restriction into an open economy model with a tradeable and a non‐tradeable sector, and I use lotteries to convexify the consumption possibilities set. This approach implies that the aggregate elasticity of labour supply becomes infinite. I compare the performance of the model with an analogous model in which the labour supply elasticity is finite. I find that there is a disconnect between the response of wages to monetary shocks and the open economy variables. The labour supply elasticity plays a more important role in the transmission of technology and government expenditure shocks to the real exchange rate and the terms of trade.     

International Transmission of Monetary Shocks and the Non‐neutrality of International Money

Monetary shocks and how they are transmitted internationally are investigated in this paper. The paper shows that where a national currency is used as an international medium of exchange, the international money is non‐neutral. In particular, an increase in the supply of the international money leads to a transfer of real resources to the international money‐issuing country from its trading partner. It also induces an expansion of the nontradable sector in the international money‐issuing country, and an expansion of the tradable sector in its trading partner. The real impact of a monetary shock is greater under a fixed exchange rate system than under a flexible exchange rate system.     

International demand and liquidity shocks in a SVAR model of the Australian economy

A structural vector autoregressive model of the Australian economy that allows for international shocks from the USA, Japan as well as world commodity prices is specified and estimated for the period 1979–1999. A block exogenous structure linking the three countries is imposed. The international linkages are modelled using a factor structure to circumvent problems from estimating large scale dynamic models. The factors are estimated recursively using a Kalman filter and are found to represent aggregate demand and liquidity shocks for the USA and Japan respectively. The key empirical result is the USA shocks are the dominant source of international shocks on the Australian economy with the Japanese economy having a dampening effect on the USA shocks. The empirical results also show that Australian monetary policy responds to domestic conditions rather than international monetary policy.     

Asymmetric information, financial intermediation, and business cycles

Summary. This incorporates a debt contracting problem with asymmetric information into a standard monetary business cycle model. The model incorporates a limited participation assumption in order to induce a liquidity effect of monetary shocks and propagate monetary disturbances. The model economy shows that a positive money supply shock generates a decrease in nominal interest rates and an increase in output level. Asymmetric information amplifies the response of capital to the money supply shock, but does not propagate them in other ways. When the monetary shock is an innovation in reserve requirements, it induces a persistent response of the economy. Received: March 20, 1998; revised version: 1 April 1998     

Supply and demand factors in the output decline in East and Central Europe

What are the relative weights of supply and demand factors in generating the output declines observed in Poland during its transition to the market? And how important are the factors that fit under the rubric of “supply and demand” in comparison to other potential reasons for the output decline, especially adjustment away from the Soviet-style economic system? The initial decline seems to have been due to a combination of aggregate demand shocks associated with the stabilization, declines in inventory investment due to the transition from a shortage economy, and especially shifts in demand away from socialized sector industry towards other sectors of the economy. Growth has come primarily from expansion in new sectors, such as services and residential construction, and in new enterprises. The applicability of one-good macroeconomics is limited in understanding either the output decline or the subsequent growth in Poland.     

International trade,foreign direct investments,and firms’ systemic risk : Evidence from the Netherlands

This paper measures the contribution of firms in the financial and non-financial sectors to systemic risk. We quantify systemic risk as possible risk spillovers from individual firms to the economy by taking into account time-varying linkages between the firm and the economy. Based on a novel dataset that combines data on international trade and foreign direct investments with daily stock data for 67 Dutch listed companies from 2006–2015, our results indicate that high systemic risk contributions are not only present in the financial sector, but also occur in other sectors of the economy. We find that firms within the financial sector are more capable than non-financial firms of reverting to their pre-financial crisis level of systemic risk contribution. Having examined the potential role globalization fulfills in determining systemic risk, we find two main opposing effects. First, firms in internationally trade-intensive sectors contribute less to systemic risk than firms in sectors with low trade intensity. Second, systemic risk rises when firms are engaged in foreign direct investment activity, suggesting that international networks and global supply chains contribute to systemic risk propagation. Our empirical results imply that macro-prudential policy aimed at monitoring systemic risk should be extended to non-financial sectors and should take into consideration globalization measures, such as foreign direct investments and global supply chains.

Oil prices and economic downturns: the case of Spain

We address the macroeconomic effects of an oil price shock in Spain. We apply a vector autoregression model (VAR) analysis to quarterly data for the Spanish economy since 1986, to elucidate the effects of variations in the oil price on the economy, considering the three main causes of disruptions in the oil markets: oil supply shocks, oil demand shocks and oil-specific (precautionary) demand shocks. We conclude that the effects in Spain strongly depend on the type of shock: the consumer price index (CPI) has mainly been influenced by oil demand shocks; output has only reacted to oil supply shocks; and monetary policy has mainly reacted after precautionary shocks. Second-round effects caused by the behaviour of nominal wages have not been found. Additionally, we discuss two facts: the ability of firms to increase markups in a context of rising demand and the procyclical role of monetary policy when faced with oil demand shocks.     

Inequality and the business cycle: evidence from U.S. survey data

ABSTRACT

We study the effects of macroeconomic shocks on measures of economic inequality obtained from U.S. survey data. To identify aggregate supply, aggregate demand, and monetary policy shocks, we estimate vector autoregressions and impose sign and zero restrictions on impulse response functions. We find that the effects of the macroeconomic shocks on inequality depend on the type of shock as well as on the measure of inequality considered. Contractionary monetary policy shocks increase expenditure and consumption inequality, whereas income and earnings inequality are less affected. Adverse aggregate supply and demand shocks increase income and earnings inequality, but reduce expenditure and consumption inequality. Our results suggest that different channels dominate in the transmission of the shocks. The earnings heterogeneity channel is consistent with the inequality dynamics after monetary policy shocks, but it appears to be less crucial when the economy is hit by either aggregate supply or aggregate demand shocks. Using variance decompositions, we find that although the macroeconomic shocks account for large shares of the variation in the macroeconomic variables, their contributions to the dynamics of the inequality measures are limited.     

A K% MONEY GROWTH LEADERSHIP RULE IN AN INTERNATIONAL MONETARY POLICY GAME

This paper examines a version of the Friedman k% money growth rule in an open economy monetary policy game. Using the two-country model proposed by Canzoneri and Henderson (1991), we show that, in response to asymmetric aggregate demand shocks, the Pareto-efficient outcome can be achieved by a policy that we call a k% money growth leadership rule. Following that rule, one country, the leader, sets her money supply growth rate, and the follower sets her money supply growth rate so as to keep the sum of nominal money supply growth at k%. We show that this policy yields the same outcome as does cooperative equilibrium. We also show that alternative policy rules, such as keeping exchange-rate adjusted money supply growth at k%, or forming a currency union, will not lead to the Pareto-efficient outcome in response to these demand shocks.

On the choice between capital import and labor export

The paper analyses some questions arising in connection with inflow of foreign capital into a host country and its free zone. When capital is mobile between sectors capital import into any part of the economy decreases welfare. With sector-specific capital, import of capital into the protected sector (export sector) decreases (increases) welfare. If capital import into the export sector of the domestic zone is infeasible, there may be a case for establishing a free zone and allowing capital import exclusively there. With a suitable tax policy, capital import into the free zone will always be beneficial.
