Essays on output and real exchange rate dynamicsKhan, Hashmat Ullah 05 1900 (has links)
There are two key observations in international macroeconomics which pertain to output
and real exchange rate dynamics. First, fluctuations in national output around its long-run
growth path are very persistent. Second, fluctuations in real exchange rates are very
persistent. The sticky price framework offers an explanation for both phenomena. The
first and second essay of this thesis take an empirical approach to test the predictions of
this framework.
In the first essay I test the prediction of the sticky price model for output dynamics
using annual IFS data on 51 countries over the period 1950 -1996. The model predicts that
price stickiness should be less important in high inflation countries and therefore output
fluctuations less persistent. I find that, this inverse relationship is statistically insignificant
in the international data. A similar result holds for OECD countries. In the empirical
implementation I explicitly control for the within-country time variation in inflation by
first characterizing the inflationary environment using the long-run movements in inflation
(trend inflation), and secondly, by excluding episodes of hyperinflation. The analysis shows
that when the within-country time variation in inflation is ignored, there is support for
the prediction. For instance, the inverse relationship between persistence in deviations of
output from its long-run growth path and average inflation is statistically significant in
the full sample. However, the exclusion of a few episodes of hyperinflation renders this
relationship statistically insignificant.
In the second essay I investigate the prediction of the sticky price model for real exchange
rate dynamics using annual IFS data on 49 countries over the period 1972-1996.
The model predicts that deviations of real exchange rates from purchasing power parity
should be less persistent, in high inflation countries. The empirical analysis reveals that
the support for such an inverse relationship is extremely fragile. In particular, eliminating
episodes of hyperinflation renders this relationship statistically insignificant.
The lack of evidence in favour of the two predictions of the sticky price model is problematic
since this model is extensively used as a microfoundation for understanding output
and real exchange rate fluctuations.
In the third essay I take a structural approach to qualitatively explore the role of slow
diffusion of new products in propagating the effect of technology shocks on output. I
present a multi-sector dynamic general equilibrium model in which the creation of new
products requires real resources. These products are beneficial for the economy but only
upon complete diffusion. However, this diffusion is not instantaneous. I find that relative
to a model in which there is instantaneous diffusion of new products, the qualitative
output dynamics are similar to what is observed in the U.S. data. This warrants further
quantitative investigation. / Arts, Faculty of / Vancouver School of Economics / Graduate

Testing for neutrality and rationality with an open-economy model: the case of CanadaAhking, Francis W. January 1981 (has links)
A small open economy model which incorporated. the rational expectations - natural rate hypothesis was constructed. The resulting model indicated that to the extent that foreign monetary policies may affect the relative price of domestic to foreign goods, the domestic unemployment rate was not neutral with respect to foreign monetary policies.
Using Canada as the small open economy and the United States as the rest of the world, the weak open economy version of the natural rate hypothesis was empirically tested for both the flexible and the fixed exchange rate periods. The empirical methodology employed was the Granger causality test. The results based on the goodness of fit test indicated that for all the exchange rate regimes, the Canadian unemployment rate was rtot Granger caused by any causal variables considered. However, the results based on a comparison of the postsample forecasting performance were different. For the first flexible exchange rate. period, 1953-1962, we found that the Canadian unemployment rate was Granger caused by the foreign price level. However, this result was consistent with the weak open economy version of the natural rate hypothesis. We also found that the foreign unemployment rate Granger caused theCanadianunemployment rate in the second flexible rate period, 1970-1979. But, this did not damage the natural rate hypothesis since the natural rate hypothesis does not preclude real variables from having a systematic effect on the Canadian unemployment rate.
The tests for rationality with the Canadian price level equations for both the flexible and the fixed exchange rate periods were inconclusive. First, we were not able to detect a breakpoint in the foreign and domestic money rules. The alternate tests of rationality which examined whether the relevant variables were included in the Canadian price level equations were also inconclusive because of a high degree of multicollinearity between the variables. / Ph.

Incorporating default risk into the Black-Scholes model using stochastic barrier option pricing theoryRich, Don R. 06 June 2008 (has links)
The valuation of many types of financial contracts and contingent claim agreements is complicated by the possibility that one party will default on their contractual obligations. This dissertation develops a general model that prices Black-Scholes options subject to intertemporal default risk using stochastic barrier option pricing theory. The explicit closed-form solution is obtained by generalizing the reflection principle to k-space to determine the appropriate transition density function. The European analytical valuation formula has a straightforward economic interpretation and preserves much of the intuitive appeal of the traditional Black-Scholes model. The hedging properties of this model are compared and contrasted with the default-free model. The model is extended to include partial recoveries. In one situation, the option holder is assumed to recover α (a constant) percent of the value of the writer’s assets at the time of default. This version of the partial recovery option leads to an analytical valuation formula for a first passage option - an option with a random payoff at a random time. / Ph. D.

Lower inflation : ways and incentives for central banksGeissler, Johannes January 2011 (has links)
This thesis is a technical inquiry into remedies for high inflation. In its center there is the usual tradeoff between inflation aversion on the one hand and some benefit from inflation via Phillips curve effects on the other hand. Most remarkable and pioneering work for us is the famous Barro-Gordon model - see (Barro & Gordon 1983a) respectively (Barro & Gordon 1983b). Parts of this model form the basis of our work here. Though being well known the discretionary equilibrium is suboptimal the question arises how to overcome this. We will introduce four different models, each of them giving a different perspective and way of thinking. Each model shows a (sometimes slightly) different way a central banker might deliver lower inflation than the one shot Barro-Gordon game at a first glance would suggest. To cut a long story short we provide a number of reasons for believing that the purely discretionary equilibrium may be rarely observed in real life. Further the thesis provides new insights for derivative pricing theories. In particular, the potential role of financial markets and instruments will be a major focus. We investigate how such instruments can be used for monetary policy. On the contrary these financial securities have strong influence on the behavior of the central bank. Taking this into account in chapters 3 and 4 we come up with a new method of pricing inflation linked derivatives. The latter to the best of our knowledge has never been done before - (Persson, Persson & Svenson 2006), as one of very view economic works taking into account financial markets, is purely focused on the social planer's problem. A purely game theoretic approach is done in chapter 2 to change the original Barro-Gordon. Here we deviate from a purely rational and purely one period wise thinking. Finally in chapter 5 we model an asymmetric information situation where the central banker faces a trade off between his current objective on the one hand and benefit arising from not perfectly informed agents on the other hand. In that sense the central bank is also concerned about its reputation.

Two essays on derivatives markets. / CUHK electronic theses & dissertations collection / Digital dissertation consortium / ProQuest dissertations and thesesJanuary 2001 (has links)
The development and introduction of financial derivatives have great impact on modern finance. Option pricing theory has become a powerful tool to value and to understand these innovations. It is also an indispensable tool to calculate hedge ratios for risk measurement and management. On the one hand, the introduction of new financial derivatives has been blamed for making financial market more volatile and risky as evidenced in the financial markets of the USA and Japan, especially during the expiration of index futures and index options, On the other hand, the applicability of new pricing models to hedging strategies is essential in monitoring and managing option positions. This study tries to give some answers on first: whether the expiration of financial derivatives increases the volatility of the Hong Kong stock market; second: whether we can better hedge by straightly applying more elaborated option valuation models replacing the standard Black-Scholes model, which market participants commonly employed for hedging option positions. Part I of this article addresses the first question while Part II studies the second question. / Yung Hei Ming. / Source: Dissertation Abstracts International, Volume: 62-09, Section: A, page: 3138. / Supervisor: Zhang Hua. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2001. / Includes bibliographical references. / Electronic reproduction.

Technical analysis and market inefficiency: a study of the Hong Kong stock market. / CUHK electronic theses & dissertations collection / Digital dissertation consortium / ProQuest dissertations and thesesJanuary 1997 (has links)
All these results indicate that the hypothesis of weak-form market efficiency has limited applicability in the Hong Kong stock market and that recognised inefficiencies are strongly associated with the information of trend-chasing technical analysts. The results are also consistent with the findings of a theoretical model proposed in this dissertation. In particular, the model suggests that trend-chasing behaviour, together with uncertainty about intrinsic values, contributes to market inefficiency. / This dissertation studies the relationship between the use of trend-chasing technical analysis and inefficiency in the Hong Kong stock market. To answer how widespread use of technical analysis can influence stock prices, a simple equilibrium model is developed. It is shown that trend-chasing behaviour, together with uncertainty about intrinsic values, leads to market inefficiencies in the form of overshooting, positive autocorrelation of short-horizon returns, mean reversion and excess volatility. / To empirically test whether market inefficiency is associated with the information of trend-chasing technical analysts, this dissertation focuses on the Hong Kong stock market, in which technical analysis is widely used. The data covers daily closing values of the Hang Seng Index (HSI) in Hong Kong from 1969 to 1992. The results show that the buy and sell signals obtained from MA rules, which are commonly used indicators of technical analysis in the market, are strongly associated with abnormal price behaviour. For instance, when changes in these MA signals are observed, short-run abnormal price behaviour is noted. That is, stock prices tend to rise when the MA rules change to buy signals and tend to fall when they change to sell signals. Also, autocorrelation in daily returns appears to differ for periods following buy and sell signals. Daily returns tend to be more autocorrelated when the MA rules provide buy signals and less autocorrelated when they provide sell signals. Moreover, when most MA rules show buy signals, mean reversion is more pronounced in subsequent dates. Furthermore, fund managers in Hong Kong can benefit from using the buy and sell signals because they consistently provide information allowing for superior market timing. / by Wong Chak-sham Michael. / Source: Dissertation Abstracts International, Volume: 59-09, Section: A, page: 3579. / Thesis (Ph.D.)--Chinese University of Hong Kong, 1997. / Includes bibliographical references (p. 134-145). / Electronic reproduction.
