INTERNATIONAL BUSINESS CYCLES IN EMERGING MARKETS

I document cyclical behavior of real exchange rates (RERs) in emerging and developed economies: stronger RER procyclicality coincides with larger relative volatility of consumption and more countercyclical trade balance. I then reevaluate the sources of fluctuations in emerging economies using an international business cycle model estimated to match the behavior of the RERs. Interest rate shocks, without any frictions, account for most of output fluctuations. This result is driven by imperfect substitution between domestic and foreign goods, which dampens the impact of trend shocks and accentuates the impact of interest rate shocks on output and consumption.     

A Tale of Two Currencies: the Asian Crisis and the Exchange Rate Regimes of Hong Kong and Singapore

Hong Kong has maintained a pegged exchange rate since 1983, while Singapore has been on a floating regime since the early 1970s. This paper provides an interpretation of the different performance of the Hong Kong and Singapore economy that could be attributable to the differences in their exchange rate regime. We develop a model that can help to interpret the differences in both the longer run trends in inflation and real exchange rates in Hong Kong and Singapore as well as the short differences in macroeconomic and real exchange rate volatility. The difference in the response of the two economies to the Asian crisis is also consistent with our model.     

The propagation of U.S. shocks to Canada: Understanding the role of real financial linkages

This paper examines the role of financial frictions in affecting the transmission of U.S. real and financial shocks to Canada using a dynamic stochastic general‐equilibrium model with an active banking sector and financial frictions. We find that the U.S. banking and interbank markets can be a potentially important source of variability of Canadian output and inflation—consistent with the financial crisis. The presence of both the demand and the real supply sides of credit in the model help to capture the stylized facts of both the domestic and the international business cycles.     

Impact of US monetary policy rate shock and other external shocks on the Hong Kong economy: A factor‐augmented vector autoregression approach

This paper uses the factor‐augmented vector autoregression framework to study the impact on the Hong Kong economy of the diverging monetary policies by the Fed, the European Central Bank (ECB) and the Bank of Japan as well as the slowdown of the Mainland economy. The empirical results show that shocks in US monetary policy rate mainly affect interest rate‐sensitive sectors in Hong Kong and that monetary easing from the European Central Bank and the Bank of Japan somewhat offsets the impact of tightening of the Fed. The transmission of external shocks is through trade and capital markets. Real variables such as real GDP growth and the unemployment rate are more sensitive to the economic slowdown in Mainland China. It is estimated that the combined effect of the four external shocks will on average lower Hong Kong's quarterly GDP growth by 0.6 percentage points and quarterly inflation by 0.2 percentage points in the first four quarters. However, Hong Kong's financial stability, particularly with regard to loan quality, banks’ capital and liquidity, is well maintained by macroprudential policies, suggesting that Hong Kong's financial system is resilient to external shocks.     

Monetary policy in a financial crisis

What are the economic effects of an interest rate cut when an economy is in the midst of a financial crisis? Under what conditions will a cut stimulate output and employment, and raise welfare? Under what conditions will a cut have the opposite effects? We answer these questions in a general class of open economy models, where a financial crisis is modelled as a time when collateral constraints are suddenly binding. We find that when there are frictions in adjusting the level of output in the traded good sector and in adjusting the rate at which that output can be used in other parts of the economy, then a cut in the interest rate is most likely to result in a welfare-reducing fall in output and employment. When these frictions are absent, a cut in the interest rate improves asset positions and promotes a welfare-increasing economic expansion.     

Foreign interest rate shocks and exchange rate regimes in East Asia

Using a theoretical dynamic stochastic general equilibrium model and an empirical panel vector autoregression, we assess the transmission of foreign real interest rate shocks on the volatility of various key macroeconomic variables in nine small open economies in East Asia taking into account the role of exchange rate regimes. Both the theoretical and empirical findings confirm the hypothesis that flexible exchange rate may work as a shock absorber when the economy is hit by foreign real interest rate shocks. The findings suggest a clear trade-off between the volatility of real exchange rate and real output to foreign interest rate shocks, both the US and G7 real interest rates, where the responses of real output are mitigated in countries that have more flexible exchange rate regime.     

The equity price channel in a New-Keynesian DSGE model with financial frictions and banking

This paper studies the role of the equity price channel in business cycle fluctuations, and highlights the equity price channel as a different aspect to general equilibrium models with financial frictions and, as a result, emphasizes the systemic influence of financial markets on the real economy. We develop a canonical dynamic general equilibrium model with a tractable role for the equity market in banking, entrepreneur and household economic activities. The model is estimated with Bayesian techniques using U.S. data over the sample period 1982Q01–2015Q01. We show that a dynamic general equilibrium model with an equity price channel well mimics the U.S. business cycle. The model reproduces the strong procyclicality of the equity price. The equity price channel significantly exacerbates business cycle fluctuations through both financial accelerator and bank capital channels. Our results support the increasing emphasis on common equity capital in Basel III regulations. This is beneficial in terms of financial stability, but amplifies and propagates shocks to the real economy.     

Emerging economy business cycles: Interest rate shocks vs trend shocks

The recent literature studying the source of business cycles in emerging market economies (EMEs) has debated the relative importance of productivity trend shocks versus interest rate shocks coupled with financial frictions. The studies in which an important role is assigned to interest rate shocks do not force their models to match the historical paths of the world or country interest rate. We show that this leads to poorly identified interest rate shocks and inaccurate measures of contributions of shocks to EME business cycles. To address this issue, we estimate a small open economy model for Argentina and Mexico using Bayesian methods where the world and country interest rate series in the model are forced to match their data counterparts. This estimation strategy results in larger variations in interest rate shock and, therefore, shifts explanatory power away from trend shocks towards interest rate shocks, although both shocks remain important.     

Fiscal deficits,banking crises and policy reversal in a semi-open economy

We study the effect of domestic policies and external shocks in a semi-open economy characterized by incomplete liberalization of the financial sector. We argue that in such transition economies stabilization programs can have a negative impact on the fiscal imbalances, offsetting to some extent the very achievement of the stabilization program. We develop a simple general equilibrium model which allows propagation of shocks in the presence of government guarantees and imperfect capital mobility. We also empirically test the impact of positive foreign interest shock on the Indian economy using a reduced form VAR approach. The econometric evidence, though broadly consistent with the main predictions of the model, suggests no significant impact of foreign interest rate shock on output and credit. We conclude that incomplete liberalization of the financial sector in transition economies has two effects. It reduces i) exposure to external financial shocks (like the current credit crisis) and ii) ability to deal with real sector shocks (which may arise from global recession in the medium term) due to endogenous policy reversals and presence of government guarantees.     

Sources of business fluctuations: Financial or technology shocks?

Despite the widespread belief that technology shocks are the main source of business fluctuations, recent empirical studies indicate that in the absence of financial frictions, a shock to the marginal efficiency of investment is the main source and is closely related to financial conditions for investment. We incorporate a financial accelerator mechanism and two types of financial shocks to the external finance premium and net worth in a dynamic stochastic general equilibrium model with shocks to the marginal efficiency of investment, the investment-good price markup, and the rates of neutral and investment-specific technological changes. This model is estimated using eleven US time series that include data on loan, net worth, the loan rate, and the relative price of investment. Our estimation results show that the (non-stationary) neutral and investment-specific technology shocks primarily drive output and investment fluctuations, while the external finance premium shock plays an important role for investment fluctuations. This financial shock induced substantial falls and subsequent sharp hikes in the external finance premium and caused boom–bust cycles over the past two decades.     

New evidence on breaking trend functions in real GDPs from Great China Economic Area

This article explores the difference in the time series property of economic output for the Great China Economic Area (GCEA) (Mainland China, Hong Kong and Taiwan). Using the powerful Kim and Perron (2009) unit root test and real GDPs over the period 1992–2014 as the study sample, results indicate the presence of a break for all economies that corresponds to the Asian financial crisis. Additionally, allowing for a break leads to the rejection of the unit root hypothesis for Taiwan only. Important implications are provided. First, considering the presence of a break in testing for nonstationarity is important or false conclusions can be drawn. Second, given the stationarity of GDP found for Taiwan only, investors should look beyond any local economic shocks and focus more on world economy development when investing in Taiwan. By contrast, investors in Mainland China and Hong Kong should pay attention to any shock because it is likely to be persistent. Third, relevant authorities should recognize that any government policy intended to promote long-run economic growth may be ineffective in Taiwan whereas it can be more effective in Mainland China and Hong Kong.     

Emerging Market Business Cycles: Recent Advances

Higher variability of consumption relative to output and strong countercyclicality of the trade balance are important regularities of emerging market business cycles. This paper surveys the recent advances in the literature with a goal to understanding the main drivers of these regularities. The literature suggests that trend shocks or countercyclical interest rate shocks are useful modeling tools, but these shocks need to be amplified through inherent frictions to capture these two regularities with realistic calibrations. Informational frictions in expectation formation and search-matching frictions in the labor market appear to provide powerful amplification to trend shocks and countercyclical interest rate shocks, respectively.     

Housing market volatility connectedness among G7 countries

This study investigates international linkages among housing markets in the G7 countries, using the connectedness methodology developed in Diebold and Yilmaz (2012, 2015). We find that volatility connectedness varies over the business cycle, with a surge during the global financial crisis. We also show that the United States and Italy were major net transmitters of housing market volatility shocks to other countries during the global financial crisis and the European debt crisis, respectively.     

MONEY,CAPITAL, AND EXCHANGE RATE FLUCTUATIONS*

We explore how the informational frictions underlying monetary exchange affect international exchange rate dynamics. Our perfectly flexible price model is capable of producing endogenously rigid international relative prices in response to technology and monetary shocks. The model is capable of accounting for the empirical regularities that the real and nominal exchange rates are more volatile than U.S. output, and that the two are positively and perfectly correlated. The model is also consistent with other standard real business cycle facts for the United States.     

FINANCIAL RISK AND UNEMPLOYMENT

There is a strong correlation between corporate interest rates, their spreads relative to Treasuries, and the unemployment rate. We model how corporate interest rates affect equilibrium unemployment and vacancies, in a Diamond–Mortesen–Pissarides search and matching model. Our simple model permits the exploration of U.S. business cycle statistics through the lens of financial shocks. We calibrate the model using U.S. data without targeting business cycle statistics. Volatility in the corporate interest rate can explain a quantitatively meaningful portion of the labor market. Data on corporate firms support the hypothesis that firms facing more volatile financial conditions have more volatile employment.     

The role of financial frictions during the crisis: An estimated DSGE model

After the recent banking crisis in 2008, financial market conditions have turned out to be a relevant factor for economic fluctuations. This paper provides a quantitative assessment of the impact of financial frictions on the U.S. business cycle. The analysis compares the original Smets and Wouters model (2003, 2007) with an alternative version augmented with the financial accelerator mechanism á la Bernanke, Gertler and Gilchrist (1996, 1999). Both versions are estimated using Bayesian techniques over a sample extended to 2012. The analysis supports the role of financial channels, namely the financial accelerator mechanism, in transmitting dysfunctions from financial markets to the real economy.The Smets and Wouters model, augmented with the financial accelerator mechanism, is suitable to capture much of the historical developments in U.S. financial markets that led to the financial crisis. The model can account for the output contraction in 2008, as well as the widening in corporate spreads, and supports the argument that financial conditions have amplified the U.S. business cycle and the intensity of the recession.     

MACROECONOMIC VOLATILITY AND COUNTERFACTUAL INFLATION‐TARGETING IN HONG KONG

The present paper evaluates macroeconomic adjustment in Hong Kong with an estimated dynamic stochastic general equilibrium (DSGE) model under a fixed exchange rate regime. We find that exports and world inflation shocks are the dominant sources of GDP volatility, with the risk premium taking on importance during the Asian crisis after 1997. A counterfactual simulation, assuming a flexible exchange rate regime with inflation targeting, shows that inflation would have decreased slightly, but interest‐rate volatility would have increased significantly. The welfare gains from switching out of the currency board system appear to be marginal.     

Monetary policy tradeoffs between financial stability and price stability

We analyze the impact of interest rate policy on financial stability in an environment where banks can experience runs on their short‐term liabilities forcing them to sell assets at fire‐sale prices. Price adjustment frictions and a state‐dependent risk of financial crisis create the possibility of a policy tradeoff between price stability and financial stability. Focusing on Taylor rules with monetary policy possibly reacting to banks’ short‐term liabilities, we find that the optimized policy uses the extra tool to support investment at the expense of higher inflation and output volatility.     

The recent boom–bust cycle: The relative contribution of capital flows, credit supply and asset bubbles

We use an estimated open economy DSGE model with financial frictions for the US and the rest of the world to evaluate various competing explanations about the recent boom–bust cycle. We find that the savings glut hypothesis is insufficient for explaining all aspects of the boom in the US. Relatively strong TFP growth and expansionary monetary policy are also not able to explain fully the volatility of corporate and in particular residential investment. We identify bubbles in the stock and housing market as crucial. Concerning the downturn in 2008/2009, the fall in house prices and residential investment only plays a minor role. Mortgage defaults have more explanatory power, especially in a specification of the model with a segregated equity market. Finally, the bursting of the stock market bubble was at least as important in this recession as in 2001. Because of various negative shocks hitting the economy at the same time in 2008/2009 and continued positive technology growth, not only the real interest rate declined but inflation fell rapidly and left insufficient room for monetary policy to play a similar stabilising role as in previous recessions.     

Interest rate volatility and macroeconomic dynamics: Heterogeneity matters

We examine the relation between real interest rate volatility and aggregate fluctuations for a diverse sample of countries. Compiling a new dataset including emerging and advanced countries, the substantial variation in our data yields novel results: (a) stochastic volatility outperforms Markov‐switching in representing interest rates, (b) some advanced economies can be more volatile than emerging markets, and (c) creditors take on more debt following volatility shocks. We show how an equilibrium business cycle model with uncertainty shocks can generate these facts. Sample heterogeneity produces significant parameter differences, playing an important role in distinguishing the effects of volatility shocks.
