Global financial crisis as a phenomenon of stock market overshooting

Inspired by Dornbusch’s model of exchange rate overshooting we develop a theory of stock market behaviour and its impact on the real economy. The idea is that stock market prices overshoot and undershoot their long-run equilibrium values which are determined by the development in the real economy. The overshooting is triggered primarily by a loose monetary policy. With our model we explain the genesis of the global financial crisis (GFC) 2008/2009 primarily as the result of a loose monetary policy in the USA. Following the overshooting and crash in the stock market the real economy dropped into a recession. After modelling the interaction of three markets with different speed of adjustment—money, stocks and goods—for a closed economy we expand it to an open economy and lastly study the spillovers of a financial market crisis between countries (from a large to a small country) by introducing the transmission channels of external trade or cross-border financial transactions. A long-lasting monetary easing as exhibiting by the Fed and the ECB since 2007 and 2008, respectively could—according to our model—generate another boom-bust cycle.     

Capital inflow-terms of trade ‘nexus’: Does it lead to financial crisis?

The paper models the nexus of foreign capital inflow and dynamic terms of trade to explain financial crisis in the form of sudden stop or reversal of capital inflow. Crisis in this structure is rooted in the role played by dynamic terms of trade rather than informational imperfections as generally found in the existing literature. Inspite of satisfying the regularity conditions for model consistency episodes of sudden crises get magnified due to the non-linearity of the equilibrium relations. This is the novelty of this paper and differentiates it from the standard theoretical literature, and well captures empirical evidence documented in the literature. Non-linearity plays a very important role in the model. Expectation of the exchange rate depreciation has higher potential to generate a financial crisis than shift in the risk perception of foreign lenders or supply shock in the borrowing country.

A few observations on financial liberalization and financial instability

Recent studies have conjectured that there may be a link between financial liberalization (FL) and financial instability in emerging economies. Most of these studies, however, do not investigate whether emerging economies are, in fact, becoming structurally more vulnerable to currency and banking crises. In this paper, I argue that emerging economies are becoming more susceptible to both currency and banking crises after FL. Using data for 27 emerging economies—excluding transition economies—from 1973 to the present, a univariate analysis indicates that the likelihood of currency crises may increase with stronger reactions to financial variables than to real or external trade variables. Similarly, for banking crises, interest rate, exchange rate, maturity, and default may increase, while simultaneously the support structure of the government seems to decline.     

Black market exchange rates in India: an empirical analysis

In this paper, we explore the determinants of black market (BM) exchange rates in India using annual data from 1955–1994 and integration and cointegration analysis. Two important factors, namely the import capacity of official foreign exchange reserves and restrictions on international trade, have largely been ignored as determinants of BM rates. We stress the importance of these two factors and incorporate them, with others more familiar in the literature, in our theoretical and empirical model for BM rates in India. Our empirical findings show that a low level of official foreign exchange reserves negatively and a high level of trade restrictions positively affect BM rates. We show that the flexible Bretton Woods exchange rate policies for India in 1973 have a negative impact on BM rates. The results also reveal that interest rate policies positively affect BM rates. Thus, our empirical model lends support to the trade and monetary approaches to BM rates and hence, trade restrictions with excess money supply should be removed to eliminate the BMs for forex in India.

Microeconomic analysis on the growth of trade volume in China: 1978–2007

The gravity equation is usually employed by researchers in the field of international trade to explain the growth of a country’s imports and exports volume, especially the manufactured goods. But in China, variables in the model, such as exchange rate, tariff, transportation cost, and spatial distance etc., are not sufficient to explain the riddle of China’s growth in trade volume. In fact, this growth in China’s trade volume is owing to the disintegration of production in the process of economic globalization, to the multinational corporations’ (MNC) vertical outsourcing of their manufacturing processes and procedures, and to the timely readjustment of Chinese enterprises on their strategies of participating in the international intra-product specialization. In this paper we establish an equilibrium model of intra-product specialization dominated by MNCs, and do some empirical tests on the growth in trade volume in China by using the variables including technological conditions of trade, similarity of economies, policy conditions of trade, disintegration of production and level of per capita capital equipment. The empirical results support our basic judgments.     

Three measures of East Asian currency evaluation

One of the prominent explanations for the East Asian financial crises of 1997 relies upon East Asian currency overvaluation. However, most empirical studies of these crises do not undertake serious examination of whether these currencies were overvalued. In this article, three major approaches to identifying the equilibrium exchange rate are implemented: long-run purchasing power parity (PPP), a productivity-based model, and a monetary model of the nominal exchange rate. The PPP calculations indicate that as of May 1997, the Hong Kong dollar, baht, ringgit, and peso were overvalued, and the won undervalued. In a framework that explicitly accounts for the role of productivity, substantial overvaluation of the peso is detected, but an undervaluation of the won is also uncovered. Misalignments of the ringgit and baht are small. Finally, the estimated equilibrium rates from a monetary model do not imply much deviation from short-run equilibrium at the end of June 1997. A conclusion of substantial overvaluation on the eve of the East Asian currency turmoil is not very plausible, suggesting that some alternate mechanism for generating crises - other than one involving the conventional macroeconomic fundamentals - was at work.     

Revisiting the interest rate–exchange rate nexus: a Markov-switching approach

In this paper the interest rate–exchange rate nexus and the effectiveness of an interest rate defense are investigated empirically. I present a reduced form evidence which characterizes the empirical relationship between interest rates and exchange rates. I use a Markov-switching specification of the nominal exchange rate with time-varying transition probabilities. Empirical evidence from six developing countries: Indonesia, South Korea, the Philippines, Thailand, Mexico, and Turkey indicates that raising nominal interest rates leads to a higher probability of switching to a crisis regime. Thus, the empirical results presented here may support the view that a high interest rate policy is unable to defend the exchange rate. Unlike other studies which consider linear models only, my findings are robust and consistent over different countries and crisis episodes (Asian 1997 crises, Mexico 1994 crisis, and Turkey 1994, 2001 crises). In order to explain the empirical findings, I construct a simple theoretical model by incorporating an interest rate rule in the model proposed by Jeanne and Rose (2002) [Jeanne, O., Rose, A.K., 2002. Noise trading and exchange rate regimes, Quarterly Journal of Economics. 117 (2) 537–569]. The model has multiple equilibria, and under plausible conditions, higher exchange rate volatility is associated with higher interest rates.     

Real exchange rate volatility,financial crises and exchange rate regimes

This article examines real exchange rate (RER) volatility in 80 countries around the world, during the period 1970 to 2011. Two main questions are raised: are structural breaks in RER volatility related to changes in exchange rate regimes or financial crises? And do these two events affect the permanent and transitory components of RER volatility? To answer these, we employ two complementary procedures that consist in detecting structural breaks in the RER series and decomposing volatility into its permanent and transitory components. Our results suggest that structural breaks in RER volatility coincidence with financial crises and certain changes in nominal exchange rate regimes. Moreover, our findings confirm that RER volatility does increase with the global financial crises and detect that the more flexible the exchange rate regime, the higher the volatility of the RER using a de facto exchange rate classification.

Exchange rate volatility and capital inflows: role of financial development

There is vast literature examining the impact of exchange rate volatility on various macroeconomic aggregates such as economic growth, trade flows, domestic investment, and more recently capital flows. However, these studies have ignored the role of financial development while examining the impact of exchange rate volatility on capital flows. This study aims to analyze the impact of exchange rate volatility on capital inflows towards developing countries by incorporating the role of financial development over the time period 1980–2013. In this regard, the behavior of two types of capital flows is examined: physical capital inflows measured as foreign direct investment, and financial inflows quantified through remittance inflows. The empirical investigation comprises the direct as well as indirect effect of exchange rate volatility on capital inflows. The study employs dynamic system GMM estimation technique to empirically estimate the effect of exchange rate volatility on capital inflows. The empirical results of the study identify that exchange rate volatility dampens both physical and financial inflows towards developing countries. The indirect impact of exchange rate volatility through financial development, however, turns out positive and statistically significant. This finding reflects that financial development helps in reducing the harmful impact of exchange rate volatility on capital inflows. Hence, the study concludes that a developed financial system is an important channel through which developing countries may improve capital inflows in the long run.     

The Green Solow model

We argue that a key empirical finding in environmental economics—the Environmental Kuznets Curve (EKC)—and the core model of modern macroeconomics—the Solow model—are intimately related. Once we amend the Solow model to incorporate technological progress in abatement, the EKC is a necessary by product of convergence to a sustainable growth path. We explain why current methods for estimating an EKC are likely to fail; provide an alternative empirical method directly tied to our theory; and estimate our model on carbon emissions from 173 countries over the 1960–1998 period.

Asymmetric effect of exchange rate volatility on India's cross‐border trade: Evidence from global financial crisis and multiple threshold nonlinear autoregressive distributed lag model

This paper examines the asymmetric effect of exchange rate volatility on India's cross‐border trade with its major trading partners: Japan, Germany, the United States, and China. We extend previous studies in two ways. First, we examine whether global financial crisis changes the asymmetric effect of exchange rate volatility on India's cross‐border trade. Next, we divide exchange rate volatility into quintiles and examine the effect of each quintile on cross‐border trade by using the multiple threshold nonlinear autoregressive distributed lag (MTNARDL) model. Our findings from standard nonlinear ARDL (NARDL) indicate that the asymmetric relationship between exchange rate volatility and cross‐border trade changes as a result of global financial crisis. In addition, findings from MTNARDL indicate that in short‐run, exchange rate volatility symmetrically affects India's cross‐border trade with all sample countries whereas in long‐run it asymmetrically affects cross‐border trade. Overall, these findings are very important for policy implications and open a new dimension to exchange rate volatility and trade flows.     

The comovement between exchange rates and stock prices in the Asian emerging markets

This study investigates the comovement between exchange rates and stock prices in the Asian emerging markets. The sample covers major institutional changes, such as market liberalization and financial crises, so as to examine how the short-term and long-term relations change after such events. The autoregressive distributed lag (ARDL) model proposed by Pesaran et al. (2001) is adopted, which allows us to deal with structural breaks easily, and to handle data that have integrals of different orders. Interest rates and foreign reserves are also included in the analysis to reduce potential omitted variable bias. My empirical results suggest that the comovement between exchange rates and stock prices becomes stronger during crisis periods, consistent with contagion or spillover between asset prices, when compared with tranquil periods. Furthermore, most of the spillovers during crisis periods can be attributed to the channel running from stock price shocks to the exchange rate, suggesting that governments should stimulate economic growth and stock markets to attract capital inflow, thereby preventing a currency crisis. However, the industry causality analysis shows the comovement is not stronger for export-oriented industries for all periods, such as industrials and technology industries, thus implying that comovement between exchange rates and stock prices in the Asian emerging markets is generally driven by capital account balance rather than that of trade.     

CHINA'S EQUILIBRIUM REAL EXCHANGE RATE: A COUNTERFACTUAL ANALYSIS

Abstract.  China's 'equilibrium' real effective exchange rate is explored using an adaptation of the Devarajan-Lewis-Robinson three-good general equilibrium model under a variety of assumptions about the balance of trade. The absence of secondary indices of import and export prices necessitates their construction from trade data. Some undervaluation is suggested in the lead-up to and during the financial crisis, due in part to an extraordinary accumulation of foreign reserves following exchange rate integration in 1994. If, instead, China had run a more typical trade balance prior to the crisis its real effective exchange rate would have been higher by about a tenth.     

A reappraisal of the evidence on PPP: a systematic investigation into MA roots in panel unit root tests and their implications

Panel unit root tests of real exchange rates—as opposed to univariate tests—usually reject non-stationarity. These tests, however, could be biased if the real exchange rate contained MA roots. Indeed, two independent arguments claim that the real exchange rate, being a sum of a stationary and a non-stationary component, is possibly an ARIMA (1, 1, 1) process. Monte Carlo simulations show how systematic changes in the parameters of the components, of the test equation and of the correlation matrix affect the size of first and second-generation panel unit root tests. Two components of the real exchange rate—the real exchange rate of a single good and a weighted sum of relative prices—are constructed from the data for a panel of countries. Computation of the relevant parameters reveals that panel unit root tests of the real exchange rate are severely oversized, usually much more so than simple augmented Dickey-Fuller tests. Thus, the evidence for purchasing power parity from first and second-generation panel unit root tests may be merely due to extreme size biases.

Withstanding financial crises: would trade partners help or hurt?

This article provides new empirical evidence on the losses of real activity caused by various financial shocks. Spillover effects due to foreign trade linkages deserve special attention. To this end, we estimate a modify auto-regressive process and a Seemingly Unrelated Regression Equations estimator is used to account for the dependency of one’s country growth on its trade-weighted partners growth. We run estimations on a set of currency collapses, banking crises and sovereign defaults in 49 advanced and developing countries from 1978 to 2011. The trade-weighted foreign demand effect mitigated the economic downturn following a banking or a sovereign debt crisis in all countries, while only the advanced ones benefited from it after a currency collapse. Trade-based spillover effects make banking crises more costly in the developing countries, in those that liberalize their financial account. It contrasts with what is observed during currency or sovereign debt crises.     

Were the peseta exchange rate crises forecastable during target zone period?

During the 1990s several fixed or quasi-fixed exchange rate systems collapsed. Currency crises have happened in both developed and emerging countries so it is necessary to forecast and avoid them. However, financial market crises have been extremely difficult to forecast. Economic agents' expectations are nonobservable variables that cannot be ignored in the models. In addition, if it is required to study the European case during the 1990s, the censored disposition of the exchange rate cannot be ignored either. A discrete time target zones model is proposed where these aspects are taken into account. It will be tested in a peseta/deutsche mark exchange rate framework, from June 1989 to December 1998. The results indicate differences between before and after the shift in band widths in August 1993.
