Global Liquidity,Current Account Deficit,and Exchange Rate Balance Sheet Effects in Turkey

This study investigates the current account deficit (CAD) of Turkey from the perspective of its capital account. We discuss how global liquidity conditions and monetary policies in Turkey have contributed to higher deficits through real exchange rate appreciations. We analyze the impact and consequences of exchange rate (ER) changes on the investments of non-financial firms. In the case of real ER depreciations, we find that the magnitude of the contractionary effect through balance sheets of firms with dollarized liabilities is significantly higher than the expansionary effect through trade competitiveness. We also analyze the “soft-landing” policies aimed at reducing the CAD in Turkey and estimate the rate of economic growth that must be foregone for a percentage reduction in CAD.     

The Trade Credit Channel of Monetary Policy Transmission: Evidence from Nonfinancial Manufacturing Firms in Turkey

This study investigates the trade credit channel of monetary policy transmission in Turkey by using a large panel of corporate firms and includes detailed information on balance sheets and income statements of firms that regularly reported to the Central Bank of the Republic of Turkey during the period 1996-2008. The study suggests that the composition of external finance differs considerably across firm types based on size and export performance under tight and loose financial conditions. Small and medium-size manufacturing firms and firms with a low export share are less likely to have access to bank finance, especially in tight periods. In addition, financially constrained firms with limited access to bank finance (small, low-export-share firms) tend to substitute trade credits for bank loans more aggressively in tight periods as monetary policy tightens. The large volume of trade credit on firms' balance sheets and its positive response to contractionary monetary shocks imply that the trade credit channel might subdue the traditional credit channel of monetary transmission.     

Explaining exchange rate volatility: an empirical analysis of ‘the holy trinity’ of monetary independence, fixed exchange rates, and capital mobility

This paper uses a panel of data from twenty-two countries between 1967 and 1992 to explain exchange rate volatility, focusing on potential tradeoffs between fixed exchange rates, independent monetary policy, and capital mobility. I use monetary models to parameterize monetary divergence and factor analysis to measure capital mobility. Exchange rate volatility is loosely linked to both monetary divergence and the degree of capital mobility. Interestingly, exchange rate volatility is significantly correlated with the width of the explicitly declared exchange rate band, even after taking monetary divergence and capital mobility into account.     

Self-oriented monetary policy,global financial markets and excess volatility of international capital flows

This paper explores the nature of macroeconomic spillovers from advanced economies to emerging market economies (EMEs) and the consequences for independent use of monetary policy in EMEs. We first empirically document that a US contractionary monetary policy shock leads a retrenchment in EME capital flows, a fall in EME GDP, and an exchange rate depreciation. We construct a theoretical model that can help to account for these findings. In the model, macroeconomic spillovers may be exacerbated by financial frictions. Absent financial frictions, international spillovers are minor, and an inflation targeting rule represents an effective policy for the EME. With frictions in financial intermediation, however, spillovers are substantially magnified, and an inflation targeting rule has little advantage over an exchange rate peg. However, an optimal monetary policy markedly improves on the performance of naive inflation targeting or an exchange rate peg. Furthermore, optimal policies don't need to be coordinated across countries. A non-cooperative, self-oriented optimal policy gives results very similar to those of a global cooperative optimal policy.     

投资潮涌、双重金融摩擦与货币政策传导——转型时期货币政策的结构调控功能探究

在银行融资与企业融资两大市场均存在金融摩擦的条件下,经济转型时期的“投资潮涌”蕴含重要货币经济学含义。以货币政策调控行业过剩产能为例,本文为解释转型时期中国货币政策结构调控功能构建一个理论分析框架,并对相关理论假说进行实证检验。经验证据显示:当不同产能过剩行业的企业在抵押能力信息传递上存在系统异质性时,货币政策具有显著产能调控功能,而调控作用的大小与企业产权结构以及货币政策工具类型有关。通过融合“投资潮涌”与BGG理论,本文将BGG理论中的货币政策效应异质性从企业层面拓展至行业层面,进而揭示了传统非结构性货币政策在转型经济背景下何以具有结构调控功能的理论机制。结论表明,进一步夯实金融市场微观基础,协同推进实体经济供给侧结构性改革与利率市场化改革,对于健全价格型货币政策调控体系至关重要。文章也为通过进一步完善和创新分类调控政策思路,实现灵活精准、合理适度的货币政策操作路径提供了政策启示。     

The price of gold and the exchange rate

This paper examines the theoretical relationship between the major exchange rates and the prices of internationally-traded commodities. In the empirical section, the case of gold is analyzed using forecast error data. Among other things, it is found that, since the dissolution of the Bretton Woods International monetary system, floating exchange rates among the major currencies have been a major source of price instability in the world gold market and, as the world gold market is dominated by the European currency bloc, appreciations or depreciations of European currencies have strong effects on the price of gold in other currencies.     

The impact of monetary policy on the exchange rate: evidence from three small open economies

This paper studies the impact effect of monetary policy shocks on the exchange rate in Australia, Canada, and New Zealand during the 1990s. Shocks are identified by the reaction of three month market interest rates to policy announcements that were not themselves endogenous to economic news on the same day. The main result is that a 100 basis point contractionary shock will appreciate the exchange rate by 2-3 percent on impact. The association of interest rate hikes with depreciations that is sometimes observed during periods of exchange market pressure is mainly attributable to reverse causality.     

Does easing monetary policy increase financial instability?

This paper develops a model featuring both a macroeconomic and a financial friction that speaks to the interaction between monetary and macro-prudential policy and to the role of US monetary and regulatory policy in the run up to the Subprime mortgage crisis. There are two main results. First, interest rate rigidities in a monopolistic banking system increase the probability of a financial crisis (relative to the case of flexible interest rate) in response to contractionary shocks to the economy, while they act as automatic macro-prudential stabilizers in response to expansionary shocks. Second, when the interest rate is the only available instrument, monetary policy faces a trade-off between macroeconomic and financial stability. This trade off is both qualitative and quantitative in response to contractionary shocks, while it is only quantitative in response to positive shocks. We show that a second instrument, such as a Pigouvian tax on credit to households on the demand side of the market, is needed to restore efficiency in the economy when both frictions are at work.     

Capital flows and the risk-taking channel of monetary policy

Adjustments in bank leverage act as the linchpin in the monetary transmission mechanism that works through fluctuations in risk-taking. In the international context, we find evidence of monetary policy spillovers on cross-border bank capital flows and the US dollar exchange rate through the banking sector. A contractionary shock to US monetary policy leads to a decrease in cross-border banking capital flows and a decline in the leverage of international banks. Such a decrease in bank capital flows is associated with an appreciation of the US dollar.     

贸易摩擦、宏观经济波动与经济开放程度的选择

本文构建一个包含关税冲击以及外汇风险溢价的两国开放经济DSGE模型,创新地揭示了关税冲击造成实际汇率波动的“直接效应”与“间接效应”,刻画了关税变动、贸易条件与实际汇率之间的动态关系与作用机制。我们深入分析了不同经济开放程度下贸易摩擦造成的宏观经济波动以及经济福利损失。模拟结果表明,在一定贸易开放程度下,外国加收关税一方面会导致本国贸易条件恶化,引发出口及产出下降;另一方面会导致本国汇率贬值,引发出口及产出增长。关税冲击发生后短期中汇率贬值效应占优,本国产出会出现小幅上升,随后贸易条件恶化效应逐步显现,产出持续下降。福利分析结果表明,本国适度提升贸易开放度,虽然经济福利损失会小幅上升,但福利损失增加幅度小于外国,会在贸易摩擦竞争中形成相对优势;如果本国过度提高贸易开放度,则会导致本国福利损失大幅增加,并且大于外国福利损失增幅,会在贸易摩擦竞争中形成相对劣势。因此,应适度逐步有序地提升贸易开放度。此外,本国适度推进资本账户开放的政策能够改善贸易条件,促进本国经济增长。     

The channels of monetary policy triggered by central bank actions and statements in the Australian equity market

Owing to the discrete disclosure practices of the Reserve Bank of Australia, this paper provides new evidence on the channels of monetary policy triggered by central bank actions (monetary policy announcements) and statements (explanatory minutes releases), in the Australian equity market. Both monetary policy announcements and explanatory minutes releases are shown to have a significant and comparable impact on the returns and volatility of the Australian equity market. Further, distinct from US and European studies that find strong evidence of the interest rate, bank loan and balance sheet channels and no evidence of the exchange rate channel following central bank actions, this paper finds that monetary policy impacts the Australian equity market via the exchange rate, interest rate and bank loan channels of monetary policy, with only weak evidence of the balance sheet channel of monetary policy. These channels are found to be operating irrespective of the trigger (monetary policy announcements or explanatory minutes releases), though results are somewhat weaker when examining the explanatory minutes releases. These results have important implications for central bank officials and financial market participants alike: by confirming a comparable avenue to affect monetary policy; and providing an explication of its impact on the Australian equity market.

Effects of Monetary Policy Shocks on Farm Prices and Exchange Rates in Korea

The effects of monetary policy shocks on farm prices and exchange rates in Korea are empirically investigated by using vector auto-regression models with sign restrictions on impulse responses. The main empirical results are as follows. First, (contractionary) monetary policy shocks have significantly negative effects on real farm prices. Second, the SR effect on farm prices is significant but short-lived. The dynamic response of farm prices is consistent with the predictions of the “overshooting” model. Third, the effects of monetary policy shocks on farm prices are more significant than the effects of monetary policy shocks on exchange rates.     

全球金融周期、美国货币政策与“三元悖论”

全球金融周期存在的背景下“三元悖论”是否依然成立充满争议。本文通过构建包含银行与金融摩擦的两国DSGE模型,为考察全球金融周期的形成提供了理论依据。美国货币政策通过资本流动传导到外围国金融市场,使外围国信贷利率、银行风险承担以及杠杆率与美国银行趋同,形成全球金融周期。金融渠道的传导速度快于实体经济渠道导致外围国国内经济周期与金融周期相背离,外围国想要稳定经济就不得不与美国保持同向的政策利率变化,货币政策独立性将不再存在。随着全球经济一体化进程加速,估值效应的作用越来越明显,浮动汇率制度并不能隔离全球金融周期的影响也无法保证货币政策的独立性。在资本账户开放的情况下,外围国金融市场越不发达,受全球金融周期的影响越大,货币政策越不独立。     

The impact of monetary policy shocks on stock prices: Evidence from Canada and the United States

Using structural VAR models with short-run restrictions appropriate for Canada and the United States, we empirically examine whether trade and financial market openness matter for the impact on and transmission to stock prices of monetary policy shocks. We find that, in Canada, the immediate response of stock prices to a domestic contractionary monetary policy shock is small and the dynamic response is brief, whereas in the United States, the immediate response of stock prices to a similar shock is relatively large and the dynamic response is relatively prolonged. We find that these differences are largely driven by differences in financial market openness and hence different dynamic responses of monetary policy shocks between the two countries that we model in this paper.     

The impact of monetary policy on the exchange rate: A high frequency exchange rate puzzle in emerging economies

This study investigates the impact of monetary policy shocks on the exchange rates of Brazil, Mexico and Chile. We find that even a focus on 1 day exchange rate changes following policy events – which reduces the potential for reverse causality considerably – fails to lend support for the view that associates unexpected interest rate hikes with immediate appreciations. This lack of empirical backing for the predictions of standard open economy models persists irrespective of whether we use the US Dollar or effective exchange rates, whether changes in the policy rate that were followed by exchange rate interventions are excluded, whether “contaminated” events are dropped from the analysis or whether we allow for non-linearities. We argue that it is difficult to attribute this stronger version of the exchange rate puzzle to fiscal dominance, as unexpected rate increases are not associated with increases in risk premia, and similar results are obtained in the case of Chile – a country that has had the highest possible short-term credit rating since 1995 and a debt/GDP ratio below 10%.     

人民币汇率波动对我国出口价格传递效应分析

汇率传递效应不仅影响国内总需求与总供给的均衡．而且还会影响国内货币政策实施的有效性。人民币汇率变动对我国进口价格及其他价格水平的传递程度是决定汇率调节我国贸易收支以及稳定国内物价水平的一个关键因素。本文的目的在于运用协整等方法分析人民币汇率变动对我国出口价格水平的影响,研究结果表明：无论长期内还是短期内,进出口价格对汇率波动的反应都较为敏感,不完全汇率的传递广泛存在于中国的出口企业。     

Inventories and optimal monetary policy in a small open economy

We study how inventory investment affects the design of optimal monetary policy in a New Keynesian small open economy model. We find that under producer currency pricing, when the intratemporal elasticity of substitution is smaller than 1, optimal monetary policy in our model with inventories is similar to a standard model without inventories. However, when the intratemporal elasticity of substitution is larger than 1, inventory investment increases the importance of nominal exchange rate stabilization relative to a standard model without inventories. The importance of nominal exchange rate stabilization increases with the intratemporal elasticity of substitution.     

Trade flow lags, monetary and fiscal policy, and exchange-rate overshooting

In this paper model a is constructed that combines trade slow lags with the model in the appendix to Dornbusch's seminal paper on exchange-rate dynamics. Here output is free to vary and inflation is determined by a simple Phillips curve mechanism. It turns out that, because of the trade slow lags, monetary expansion causes interest rates to decline, but the exchange rate need not oveshoot, as one would expect; whereas fiscal policy always produces overshooting. It follows that monetary policy may be a less important source of exchange-rate variability than is commonly believed, and fiscal policy more important.     

Monetary Policy,Bank Lending,and the Risk‐Pricing Channel

This paper identifies a monetary policy channel through the risk pricing of bank debt in the market for jumbo certificates of deposit (jumbo CDs). Adverse policy shocks increase debt holder perceptions of bank default, increasing the risk premia for some banks, thereby decreasing their external funding of loans. The results show that contractionary policy increases the sensitivity of jumbo‐CD spreads to leverage and asset risk for small banks, and to leverage for large banks. The results also show a distributional and aggregate effect on banking system jumbo CDs and total loans, producing a risk‐pricing (or market discipline) channel. This channel has implications for monetary and regulatory policies, and financial stability.
