Can a Lucas model with habit generate realistic conditional volatility in exchange rate returns?

In this paper, we attempt to give a theoretical underpinning to the well established empirical stylized fact that asset returns in general and the spot FOREX returns in particular display predictable volatility characteristics. Adopting Moore and Roche.s habit persistence version of Lucas model we .nd that both the innovation in the spot FOREX return and the FOREX return itself follow "ARCH" style processes. Using the impulse response functions (IRFs) we show that the baseline simulated FOREX series has "ARCH" properties in the quarterly frequency that match well the "ARCH" properties of the empirical monthly estimations in that when we scale the x-axis to synchronize the monthly and quarterly responses we find similar impulse responses to one unit shock in variance. The IRFs for the ARCH processes we estimate "look the same" with an approximately monotonic decreasing fashion. The Lucas two-country monetary model with habit can generate realistic conditional volatility in spot FOREX return.: asset pricing, CCAPM, conditional volatility, GARCH models, foreign exchange, habit persistence

Lessons from the evolution of foreign exchange trading strategies

The adaptive markets hypothesis posits that trading strategies evolve as traders adapt their behavior to changing circumstances. This paper studies the evolution of trading strategies for a hypothetical trader who chooses portfolios from foreign exchange (forex) technical rules in major and emerging markets, the carry trade, and U.S. equities. The results show that forex trading alone dramatically outperforms the S&P 500 but there is little gain to coordinating forex and equity strategies, which explains why practitioners consider these tools separately. In addition, a backtesting procedure to choose optimal portfolios does not select carry trade strategies until well into the 1990s, which helps to explain the relatively recent surge in interest in this strategy. Forex trading returns dip significantly in the 1990s but recover by the end of the decade and have greatly outperformed an equity position since 1998. Overall, trading rule returns still exist in forex markets—with substantial stability in the types of rules—though they have migrated to emerging markets to a considerable degree.Foreign exchange ; Trade

Testing for Efficiency in Selected Developing Foreign Exchange Markets: An Equilibrium-based Approach.

This paper proposes an alternative way of testing FOREX efficiency for developing countries. The FOREX market will be efficient if fully reflects all available information. If this holds, the actual exchange rate will not deviate significantly from its equilibrium rate. Moreover, the spot rate should deviate from its equilibrium rate by only transitory components (i.e. it should follow a white noise process). This test is applied to three Central & Eastern European Countries – members of the EU. Considering an LSTAR model we find no evidence of nonlinear adjustment in the misalignment series. So, linear unit root tests imply that the Poland/Euro FOREX market is efficient, the Czech/Euro FOREX market is not, while the Slovak/Euro FOREX market is quasi-efficient.FOREX efficiency; BEER; Linearity test; Unit Root.

Official Foreign Exchange Interventions in the Czech Republic: Did They Matter?

This paper studies the impact of daily official foreign exchange interventions on the Czech koruna’s exchange rate vis-à-vis the euro (German mark prior to 1999) from 1997 to 2002. Using both the event study methodology and a variety of GARCH models reveal that central bank interventions, especially koruna purchases were fairly ineffective from 1997 to mid-1998 compared to the size of the interventions. However, from mid-1998 to 2002, koruna sales were surprisingly effective in either smoothing the path of the exchange rate or even reversing the appreciating trend up to 60 days. Higher volatility triggered koruna purchases in the period from 1997 to mid-1998, which in turn leads to higher volatility. This suggests that the CNB tried in vain to calm the markets after the currency crisis. Koruna sales simply yield more forex rate volatility, a by-product of the monetary authorities’ efforts to counter excessive appreciation.http://deepblue.lib.umich.edu/bitstream/2027.42/40146/3/wp760.pd

Exchange Rate Regimes, Foreign Exchange Volatility and Export Performance in Central and Eastern Europe: Just Another Blur Project?

This paper attempts to analyze the direct impact of exchange rate volatility on the export performance of ten Central and Eastern European transition economies as well as its indirect impact via changes in exchange rate regimes. Not only aggregate but also bilateral and sectoral export flows are studied. To this end, we first analyze shifts in exchange rate volatility linked to changes in the exchange rate regimes and second, use these changes to construct dummy variables we include in our export function. The results suggest that the size and the direction of the impact of forex volatility and of regime changes on exports vary considerably across sectors and countries and that they may be related to specific periods.http://deepblue.lib.umich.edu/bitstream/2027.42/40168/3/wp782.pd

Exchange Rate Pass-Through to Consumer Prices in Nigeria

The increasing overdependence of Nigerian economy on imports has necessitated the need to continually examine the effect of exchange rate shocks in consumer prices. The paper adopts a Structural Vector autoregressive to estimate the pass-through effect of exchange rate changes to consumer prices. Using the Variance Decomposition analyses, the study found a substantially large exchange rate pass-through to inflation in Nigeria. Finding shows that exchange rate has been more important in explaining Nigeria’s rising inflation phenomenon than the actual money supply. Therefore, it is recommended that Nigerian economy focuses on policies that ensure exchange rate stability and sound monetary surveillance

An Asset Market Integration Test Based on Observable Macroeconomic Stochastic Discount Factors

There are a number of tests and measures of the degree of integration in the literature. An example is the idea that integrated markets should provide rates of return that are highly correlated with one another and that a measure of correlation provides an appropriate test. This particular idea is clearly false; for substantial periods of time we don't ever see stocks traded on the same market moving together. Specific models of what prices risk in individual markets could provide the basis of a test of integration. However, as has been widely shown, any differences between these pricing models will be subject to arbitrage by informed traders and so cannot form the basis for a test. In this paper we exploit the absence of arbitrage possibilities and the operation of the 'Law of One Price' in stochastic discount factor (SDF) theory to construct a test of integration based on a common approach to pricing assets in all markets, not only for stocks. The SDF approach that we adopt says that one SDF should price all assets as the model is not market or asset-specific.Unlike much of the literature, we adopt a direct parametric approach which takes estimates of an identical SDF from two asset markets and asks whether the price of risk associated with this SDF is the same for the two assets as SDF theory says it should. Another distinctive feature of our approach is that we employ observable macroeconomic factors. This allows us to estimate and compare the estimated risk premia in the markets concerned, with and without the integration restriction being applied. The paper uses this methodology to test market integration between the UK equity and FOREX markets. Our test rejects market integration for the consumption-based capital asset pricing model (CCAPM) and two variable SDF models based on consumption growth and inflation and on output and money growth. As equity and FOREX returns have a similar degree of variability, the finding that the risk premium in the FOREX market is generally much more variable than that in the equity market may contribute to the the test outcome.
