decentralized and concentrated investments in china and the performance of taiwanese listed electronic companies abstractever since china surpassed taiwan to become the largest exporter of electronic products dependence between the two sides has deepened which prompts taiwanese companies to go public in china this study conducted the data envelopment analysis dea and regression analysis to analyse the impacts of the depth and breadth of investments in china on the performance of taiwanese listed electronic companies the empirical results show that the breath of the investments in china has a positive correlation with the performance of taiwanese companies while the depth of investments in china has a negative and significant effect on the performances due to the companies lack of know how which leads to a high learning cost in summary companies should strategize their decentralized and concentrated investments in china

alliance strategies of small firms the paper concludes that small firms follow one of two alliance strategies when the firms are small relative to their rivals and to their market they tend to use alliances to gain economies of scale and scope when they are large in relative terms they avoid alliances this behavior is consistent with alliance usage by large firms the paper also analyzes the sources of profit for a small firm that uses a constellation of allies to compete in a scale intensive industry its profits depend on a combination of the group based advantages generated by the constellation and the share of these profits that the firm can appropriate from the group small firms face particular hazards in this regard when their bargaining power within their constellation is weak the paper illustrates these arguments with data froma small survey with case studies from the computer industry and with a simple mathematical model

domestic foreign interest rate differentials near unit roots and symmetric threshold models this paper investigates the near unit root behavior of interest rate differentials across countries using a symmetric band tar model that allows for a heteroscedastic error process we find that the time series properties of monthly short term interest differentials over the period 1974 2005 between the united states and canada france germany japan and the united kingdom can be characterized by a symmetric band tar process which can explain its near unit root behavior reported in the extant literature results significantly reject a linear model in favor of the alternative hypothesis of a two regime symmetric threshold model that exhibits significantly greater persistence within the threshold bands than when outside the threshold bands

potential pitfalls for the purchasing power parity puzzle sampling and specification biases in mean reversion tests of the law of one price the ppp puzzle is based on empirical evidence that international price differences for individual goods loop or baskets of goods ppp appear highly persistent or even nonstationary the present consensus is these price differences have a half life that is of the order of five years at best and infinity at worst this seems unreasonable in a world where transportation and transaction costs appear so low as to encourage arbitrage and the convergence of price gaps over much shorter horizons typically days or weeks however current empirics rely on a particular choice of methodology involving i relatively low frequency monthly quarterly or annual data and ii a linear model specification in fact these methodological choices are not innocent and they can be shown to bias analysis towards findings of slow convergence and a random walk intuitively if we suspect that the actual adjustment horizon is of the order of days then monthly and annual data cannot be expected to reveal it if we suspect arbitrage costs are high enough to produce a substantial band of inaction then a linear model will fail to support convergence if the process spends considerable time random walking in that band thus when testing for ppp or loop model specification and data sampling should not proceed without consideration of the actual institutional context and logistical framework of markets

resource curse or not a question of appropriability this thesis presents three self contained essays focusing on empirical questions in growth and development economics each article addresses specific questions on why countries perform differently in particular i analyse the effect of democracy on economic development the relationship between natural resources and growth and the efficiency of foreign development assistance in the first essay democracy consolidation and growth i analyse the effect of democracy on economic growth in this context i argue that an important aspect to consider is how consolidated political systems are put simply i find that it is not only a question of how democratic countries are but also how long they have been democratic in other words economic performance tends to improve with the duration of uninterrupted democracy the performance of autocracies on the other hand tends to deteriorate over time however for newly established political systems there seems to be a cost of being democratic this implies that democracies only bear their fruit after some time the analysis has important policy implications to overcome initial straits international assistance focused on democratic consolidation may be important and a very good investment in fostering long run development the second essay resource curse or not a question of appropriability together with anne boschini and jesper roine is concerned with the relation between natural resources and economic development for most laymen as well as for most economists it would seem reasonable that countries richly endowed in natural resources also benefit from this wealth however a large literature has found a systematic negative effect of natural resource abundance on economic growth we suggest that this so called resource curse is not determined by resource endowments alone but rather by the interaction between the type of resources a country possesses and the quality of institutions in the country this combination of factors determines what we call the appropriability of a resource the concept of appropriability captures the likelihood of natural resources leading to rentseeking corruption or conflicts which in turn will harm economic development our results suggest that if institutions are good enough the curse may be turned into a blessing this may explain why some countries such as norway and botswana tend to benefit from their resources while others such as angola and sierra leone do not the third and final essay of this thesis foreign sectoral aid fungibility growth and poverty reduction is a contribution to the aid efficiency literature which is concerned with the question of whether aid helps or hinders economic development foreign development assistance is often targeted on specific public expenditure sectors if this aid is not used in the sector for which it was granted e g health education it is said to be fungible and donors may end up financing something completely different from what they intended e g military expenditures the major concern about sectoral fungibility is that the alternative use of aid may be less productive or less socially useful however measuring fungibility is not sufficient to determine whether foreign sectoral aid fungibility is actually harmful what is important is how the funds treated as fungible are used the essay starts by obtaining estimates of fungibility for 57 countries the results suggest that sectoral aid is indeed largely treated as fungible by recipient countries next to assess the economic and health effects of fungibility these estimates are incorporated into an empirical model of aid and growth as well as into a model of aid and infant mortality altogether i find no evidence of more fungible sectoral aid leading to worse performance

do land revenue windfalls create a political resource curse evidence from china abstract by analyzing a panel on the political turnovers of 4390 county leaders in china during 1999 2008 we find that the revenue windfalls accrued to these officials from land sales have undermined the effectiveness of the promotion system for government officials instead of rewarding efforts made to boost gdp growth promotion is positively correlated with signaling efforts and with corruption the robust positive relationship between land revenue windfalls and political turnover or specifically promotion suggests that those who are politically connected to their superiors and those beyond the prime age for promotion are the primary beneficiaries the case for corruption is substantiated by the evidence inferred from anti corruption crackdowns which reveals that the additional effect of land revenue on political turnover and size of bureaucracy a proxy for corruption decreases significantly in crackdowns but that land revenue has no effect on city construction expenditure a proxy for signaling

cointegration and threshold adjustment this article proposes an extension to the engle granger testing strategy by permitting asymmetry in the adjustment toward equilibrium in two different ways we demonstrate that our test has good power and size properties over the engle granger test when there are asymmetric departures from equilibrium we consider an application namely whether there exists cointegration among interest rates for instruments with different maturities this issue has been widely tested with mixed results we argue that either cautious policy or possibly opportunistic behavior on the part of the federal reserve implies that an equilibrium relationship between short and long term interest rates exists but that adjustments from disequilibrium are asymmetric in nature empirical tests using u s yields confirm the asymmetric nature of error correction among interest rates of different maturities

optimal dutch disease growth models of the dutch disease such as those of krugman 1987 matsuyama 1992 sachs and warner 1995 and gylfason et al 1999 explain why resource abundance may reduce growth however the literature also raises a new question if the use of resource wealth hurts productivity growth how should such wealth be optimally managed this question forms the topic of the present paper in which we extend the growth literature on the dutch disease from a positive to a normative setting we show that the assumptions in the previous literature imply that the optimal share of national wealth consumed in each period needs to be adjusted down however some dutch disease is always optimal thus lower growth in resource abundant countries may not be a problem in itself but may be part of an optimal growth path the optimal spending path of the resource wealth may be increasing or decreasing over time and we discuss why this is the case

rent seeking and resource booms abstract this paper develops a model of rent seeking in which the opportunity cost of rent seeking is foregone entrepreneurship it provides conditions under which resource booms tend to lead to an increase in rent seeking activity and those in which they induce entrepreneurship we identify an important difference between the two activities which leads resource booms to bias gains in favour of rent seeking over entrepreneurship but we also show that this bias depends on the nature of the initial equilibrium

short term interest rates as subordinated diffusions in this article we cbaracterize and estimate the process for short term interest rates using federal funds interest rate data we presume that we are observing a discrete time sample of a stationary scalar diffusion we concentrate on a class of models in whicb the local volatility elasticity is constant and the drift has aflexible specufication to accommodate missing observations and to break the link between economic time and calendar time we model the sampling scheme as an increasing process that is not directly observed we propose and implement two new methods for estimation we find evidence for a volatility elasticity between one and onehalf and two when interest rates are high local mean reversion is smaul and the mechanism for inducing stationarity is the increased volatility of the diffusion process

the eclectic paradigm of international production a restatement and some possible extensions this article reviews some of the criticisms directed towards the eclectic paradigm of international production over the past decade and restates its main tenets the second part of the article considers a number of possible extensions of the paradigm and concludes by asserting that it remains a robust general framework for explaining and analysing not only the economic rationale of economic production but many organisational and impact issues in relation to mne activity as well

resource intensity institutions and development summary we examine the relationship between resource abundance and several indicators of human welfare consistent with the existing literature on the relationship between resource abundance and economic growth we find that given an initial income level resource intensive countries tend to suffer lower levels of human development while we find only weak support for a direct link between resources and welfare there is an indirect link that operates through institutional quality there are also significant differences in the effects that resources have on different measures of institutional quality these results imply that the resource curse is a more encompassing phenomenon than previously considered and that key differences exist between the effects of different resource types on various aspects of governance and human welfare 2005 elsevier ltd all rights reserved

the dutch disease a disease after all many third world oil producers are encountering serious problems in building up a diversified export base while west european oil and gas producers netherlands united kingdom are suffering a decline in their traded goods manufacturing sector induced by real wage pressures it is becoming increasingly clear that high but temporary oil revenues may be somewhat ora mixed blessing the quip of the economist notwithstanding the mechanism behind this unbalance is clear enough part of the oil revenues is spent on non traded goods which leads to a real appreciation i e a rise in the relative price of non traded goods in terms of traded goods this in turn draws resources out of the non oil traded sector into the non traded goods producing sector corden and neary 1982 van wijnbergen 1980 one may say that this is an efficient response to the increase in income from oil production the united kingdom mexico egypt simply should move into oil derived industries and non traded goods and forget about their manufacturing sector until oil reserves are exhausted however many developing countries are hesitant to take this advice after all the post world war ii success stories in economic development involve without exception countries that promoted their traded goods sector aggressively moreover it is a well established stylised fact that technological progress is faster in the traded non sheltered sectors of an economy than in the non traded sector balassa 1964 is an early reference considering the hypothesis that technological progress rather than taking place exogenously with the passage of time is a function of accumulated experience the concern of countries like egypt mexico or indonesia is much easier to understand since solow 1957 and denison 1962 it is known that capital accumulation explain only a small part of economic growth if most of economic growth is caused by learning by doing induced technologica

the voracity effect abstract we analyze an economy that lacks a strong legal political institutional infrastructure and is populated by multiple powerful groups powerful groups dynamically interact via a fiscal process that effectively allows open access to the aggregate capital stock in equilibrium this leads to slow economic growth and a voracity effect by which a shock such as a terms of trade windfall perversely generates a more than proportionate increase in fiscal redistribution and reduces growth we also show that a dilution in the concentration of power leads to faster growth and a less procyclical response to shocks jel f43 o10 o23 o40

cursed by resources or institutions natural resource abundant countries constitute both growth losers and growth winners and the main difference between the success cases and the cases of failure lays in the quality of institutions with grabber friendly institutions more natural resources push aggregate income down while with producer friendly institutions more natural resources increase income such a theory finds strong support in data a key question we also discuss is if resources in addition alter the quality of institutions when that is the case countries with bad institutions suffer a double resource curse as the deterioration of institutions strenghtens the negative effect of more natural resources

testing the term structure of interest rates using a stationary vector autoregression with regime switching abstract the expectations model of the term structure for us data on three and six month treasury bills for the period 1962 1 1987 3 is explored the analysis allows for the nonstationarity of the data and for unobserved stochastic switches of regime by estimating vars in the yield spread and the change in the three month rate which allow the time series processes to change between regimes in contrast to other results for the expectations model such as those of hamilton 1988 mankiw and miron 1986 and others we find that the data do not reject the model

the narrow moving band the dutch disease and the competitive consequences of mrs thatcher notes on trade in the presence of dynamic scale economies abstract this paper presents a model of trade in which comparative advantage instead of being determined by underlying attributes of countries evolves over time through learning by doing in this model arbitrary patterns of specialization once established tend to become entrenched over time the model sheds light on three widely held views that do not make sense in more conventional models first is the view that temporary protection of selected sectors can permanently alter the pattern of comparative advantage in the protecting country s favor second is the view that seemingly favorable developments such as the discovery of exportable natural resources may lead to a permanent loss of other sectors and reduce welfare in the long run third is the possibility that a temporary overvaluation of a currency due to tight money can lead to a permanent loss of competitiveness in some sectors

history lessons institutions factor endowments and paths of development in the new world the explanations offered for the contrasting records of long run growth and development among the societies of north and south america most often focus on institutions the traditional explanations for the sources of these differences in institutions typically highlight the significance of national heritage or religion we in contrast argue that a hemispheric perspective across the wide range of colonies established in the new world by the europeans suggests that although there were many influences factor endowments or initial conditions had profound and enduring effects on the long run paths of institutional and economic development followed by the respective economies

institutions and the resource curse countries rich in natural resources constitute both growth losers and growth winners we claim that the main reason for these diverging experiences is differences in the quality of institutions more natural resources push aggregate income down when institutions are grabber friendly while more resources raise income when institutions are producer friendly we test this theory building on sachs and warner s influential works on the resource curse our main hypothesis that institutions are decisive for the resource curse is confirmed our results contrast the claims of sachs and warner that institutions do not play a role

natural resources rent seeking and welfare abstract a new and very simple mechanism to explain why natural resource abundance may lower income and welfare is developed in a model with rent seeking a greater amount of natural resources increases the number of entrepreneurs engaged in rent seeking and reduces the number of entrepreneurs running productive firms with a demand externality it is shown that the drop in income as a result of this is higher than the increase in income from the natural resource more natural resources thus lead to lower welfare

short rate nonlinearities and regime switches abstract using non parametric estimation methods various authors have shown distinct non linearities in the drift and volatility function of the us short rate which are inconsistent with standard affine term structure models we document how a regime switching model with state dependent transition probabilities between regimes can replicate the patterns found by the non parametric studies to do so we use data from the uk and germany in addition to us data and include term spreads in some of our models we also examine the drift and volatility function of the term spread

rational expectations econometric analysis of changes in regime an investigation of the term structure of interest rates abstract this paper is of interest both for its methodological contribution of new tools for analyzing rational expectations models and for its substantive conclusions concerning the term structure of interest rates during the monetary experiment of october 1979 the paper studies systems subject to changes in regime interpreted here as occasional discrete shifts in the parameters governing the time series behavior of exogenous economic variables the specification is shown to be quite tractable both theoretically and empirically the technique is used to analyze yields on three month treasury bills and ten year treasury bonds during 1962 to 1987 a constant parameter linear model for short term rates is shown to be inconsistent both with the univariate time series properties of short rates and with the observed bivariate relation between long and short rates under the expectations hypothesis of the term structure an alternative nonlinear model that admits the possibility of changes in regime affords a much better description of the univariate process for short rates moreover the cross equation restrictions implied by the expectations hypothesis of the term structure are consistent with the nonlinear specification indeed the residuals of the restricted relation have a standard error of only 0 8 basis points this is a third less than that of a completely unrestricted linear regression of long rates on short rates and compares with an unconditional standard deviation of long rates of 142 basis points i conclude that once the recognition by bond traders of changes in regime is taken into account the expectations hypothesis of the term structure of interest rates holds up fairly well for these data

predator or prey parasitic enterprises in economic development abstract in many developing and transition economies mafia like activities are rampant extortion and other forms of predation lower profitability in private businesses and distort investment incentives incorporated in a model of industrialization bimodal club convergence may result economies may get stuck in a predators club characterized by a vicious cycle of poverty and predation societies with a low flow of new entrepreneurs are especially vulnerable to predation and never get out of this club poor societies with a high flow of new entrepreneurs however may grow out of the trap and join the rich producers club

network linkages and location choice in foreign direct investment this paper shows that network linkage is an important determinant of location choice in foreign direct investment fdi network linkages are divided into internal intra firm and external inter firm linkages external linkages are further separated into strategic and relational linkages we found that taiwanese firms are keen on making external linkages but are indifferent to or incapable of making internal linkages through fdi strategic linkages motivate taiwanese fdi in the united states while relational linkages facilitate taiwanese fdi in southeast asia and china small firms are more sensitive to relational linkages than large firms in their choice of fdi location

crime induced poverty traps abstract poverty makes thieves and thieves hamper economic growth we study these linkages in a model of modern sector job creation job creation has two effects higher labor demand tends to lower crime while higher output gives more to steal tending to increase crime at low levels of modernization the second effect dominates and as a consequence the model has decreasing returns to scale at higher levels of modernization there is increasing returns to scale due to declining crime the economy may end up in a poverty trap with high crime and low production or obtain full modernization with low crime rates the danger of ending up in a poverty trap has implications for economic policies we show for instance that a reform intended to improve efficiency may throw the economy into a vicious circle of increasing crime and stagnation if implemented too fast

real exchange rates and switching regimes abstract we suggest that the real exchange rate between the major currencies in the post bretton woods period can be described by a stationary 2 state markov switching ar 1 model based on the forecast performance we find that this model outperforms two competing models where the real exchange rate is nonstationary we also find that the existence of different regimes as in the markov switching model is consistent with the common finding of unit roots in real exchange rates

small firms as international players in this paper using aggregate data from the u s bureau of economic analysis the author explores the strategies small u s based foreign investing firms follow in their international activities the aggregate study supports the findings of an earlier study of a few small firms with international activities these firms have a lower than expected tendency to form minority owned affiliates abroad an analysis of the industries in which these small foreign investing firms operate supports the notion that these firms follow specific strategies uncovered in the small scale study finally the paper ties the findings to alliance strategies of small firms

learning by doing and the dutch disease this paper develops a model of learning by doing and the dutch disease that extends the earlier literature in two ways first it is assumed that both the traded and the non traded sector can contribute to learning second it is assumed that there are learning spillovers between the sectors it is shown that within such a model a foreign exchange gift results in a real exchange rate depreciation in the long run due to a shift in the steady state relative productivity between the traded and the non traded sector in contrast to standard models of the dutch disease production and productivity in both sectors may go up or down the conditions for the different cases are worked out

a dynamic decision model of smes fdi many scholars generally believe that small and medium sized enterprises smes in comparison to large firms are at a disadvantage in foreign direct investment fdi however new evidence suggests that smes also play an important role in fdi why do they undertake risk in other countries we are interested in what factors significantly motivate them to go abroad taiwan s smes play a vital role in her economic development and outward fdi and this study therefore focuses on the outward fdi of taiwan s smes we apply the hazard rate approach to perform an empirical analysis taking into consideration the conditional probability of the element of time among smes the lower the degree of capital intensities the larger the firm sizes the higher the export ratios or the larger the level of r d intensities are the greater the intention will be to undergo fdi the major factors motivating taiwanese smes to conduct fdi in recent years are utilizing local labor expanding markets and following major clients

the process of direct foreign investment a considerable amount of the economic literature concerning direct foreign investment dfi has been devoted to the question of why firms choose to become multinational this question has occupied both theorists of multinational enterprises mne s 1 6 7 9 11 and those who have done statistical studies of mne s 2 3 8 certainly a firm s decision to invest directly abroad rather than export goods produced at a single location is a central question in the analysis of mne s as the number of mne s continues to rise though it becomes increasingly useful to investigate the behavior of firms that are already multinational is it true for example that the factors that initially make a firm more likely to become a multinational also cause the firm to increase the size of its foreign investment kogut has argued that t here is a fallacy of explanation of genesis in failing to distinguish between the initial investment decision and the subsequent incremental investment flows 10 38 he argues that dfi should be analyzed as a flow and that the mne engages in this flow of foreign investment in order to capitalize on the flexibility inherent in the firm s multinationality thus dfi should be studied as a process and not as a onetime decision this paper formally develops this idea in the context of a model of international trade developed by helpman that incorporates mne s 6 the rest of this paper is organized as follows section ii contains a brief summary of the model that helpman has developed as an extension of helpman the model is used to develop the distinction between the decision to become multinational and the decision to add incremental flows to the direct foreign investment section iii discusses a method for testing whether there is a distinction between the decision to become a multinational and the decision to continue flows of incremental investment section iv presents the results of such a test using a sample of u s multinational firms conclusions are presented in section v

minerals institutions openness and growth an empirical analysis competing explanations of the resource curse are tested using panel data the data support the existence of a mineral resource curse for developing countries with weak institutions consistent with the hypothesis that owners of mineral resources use weak institutions and openness to trade to stifle the development of human capital to the detriment of growth in other sectors of the economy manufacturing imports substitute for the development of domestic production so openness to trade correlates with lower growth in mineral dependent economies the dutch disease and debt overhang explanations of the resource curse are not supported

political foundations of the resource curse in this paper we argue that the political incentives that resource endowments generate are the key to understanding whether or not they are a curse we show 1 politicians tend to over extract natural resources relative to the efficient extraction path because they discount the future too much and 2 resource booms improve the efficiency of the extraction path however 3 resource booms by raising the value of being in power and by providing politicians with more resources which they can use to influence the outcome of elections increase resource misallocation in the rest of the economy 4 the overall impact of resource booms on the economy depends critically on institutions since these determine the extent to which political incentives map into policy outcomes countries with institutions that promote accountability and state competence will tend to benefit from resource booms since these institutions ameliorate the perverse political incentives that such booms create countries without such institutions however may suffer from a resource curse

a parametric nonlinear model of term structure dynamics recent nonparametric estimation studies pioneered by ait sahalia document that the diffusion of the short rate is similar to the parametric function r superscript 1 5 estimated by chan et al whereas the drift is substantially nonlinear in the short rate these empirical properties call into question the efficacy of the existing affine term structure models and beg for alternative models which admit the observed behavior this article presents such a model our model delivers closed form solutions for bond prices and a concave relationship between the interest rate and the yields we show that in empirical analyses our model outperforms the one factor affine models in both time series as well as cross sectional tests article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

revisiting the oil curse does ownership matter summary a large body of literature finds a negative relationship between oil abundance and economic growth the existing empirical evidence on the oil curse however does not account for variations in the ownership of oil this article investigates whether the effect of oil abundance on growth varies with ownership structures it also investigates whether pre existing institutional conditions influence the effect of oil abundance across different ownership structures using a novel database on ownership structures and employing a panel fixed effects estimation method it analyzes a sample of oil exporting developing countries during the period 1984 2005 the results show that the effect of oil abundance on growth varies with ownership structures and is also influenced by the quality of pre existing institutions under state ownership and control oil abundance reduces growth when the institutional quality is poor but increases growth when the institutional quality is good under private ownership on the other hand oil abundance increases growth when the institutional quality is poor but reduces growth when the institutional quality is good the results suggest that ownership matters and countries can avoid the oil curse by choosing an appropriate ownership structure given their pre existing institutional circumstances the policy advice in this article is adopt state ownership and control if the institutions are strong if the institutions are weak transfer ownership to foreign oil companies

transactions costs and nonlinear adjustment in real exchange rates an empirical investigation eolquilibrium models of real exchange rate determination in the presence of transactions costs imply a nonlinear adjustment process toward purchasing power parity ppp conventional cointegration tests which ignore the effect of transactions costs may be biased against the long run ppp hypothesis our results using both monthly data for the interwar period and annual data spanning two centuries clearly reject the linear framework in favor of an exponential smooth transition autoregressive process the systematic pattern in the estimates of the nonlinear models provides strong evidence of mean reverting behavior for ppp deviations and helps explain the mixed results of previous studies

the internationalization of small and medium sized enterprises a policy perspective small and medium sized firms play an impor tant role in the process of creative destruction the focus of the paper is on the international diffusion of small and medium sized firms innovations small and medium sized firms face two challenges in globalization property rights protection and barriers to entry we suggest that these barriers can frequently be circumvented by using existing multinationals as interna tional conduits for small and medium size firms innovations however such intermediated modes of expansion is adversely affected by transaction difficulties and intermediator s rent extraction we raise two categories of questions i is the private sector systematically making the wrong choice between the direct and intermediated mode of international expansion and ii what should be the policy guidelines to improve the overall rate of international diffusion of innova tion by small and medium sized enterprises

natural resources and economic growth the role of investment is it possible that excessive reliance on natural resources affects saving and investment in a way that retards economic growth and thus in the long run the level of output per capita this paper reviews the literature explores the data and compares and contrasts the explanatory power and interplay of natural resources and civil liberties our proxy for institutional variables currently under scrutiny in the literature we propose that natural resource dependence may be viewed as an exogenous factor that impedes economic growth and investment as well as institutions even if we stress that natural resource abundance may be good for growth

bootstrapping financial time series it is well known that time series of returns are characterized by volatility clustering and excess kurtosis therefore when modelling the dynamic behavior of returns inference and prediction methods based on independent and or gaussian observations may be inadequate as bootstrap methods are not in general based on any particular assumption on the distribution of the data they are well suited for the analysis of returns this paper reviews the application of bootstrap procedures for inference and prediction of financial time series in relation to inference bootstrap techniques have been applied to obtain the sample distribution of statistics for testing for example autoregressive dynamics in the conditional mean and variance unit roots in the mean fractional integration in volatility and the predictive ability of technical trading rules on the other hand bootstrap procedures have been used to estimate the distribution of returns which is of interest for example for value at risk var models or for prediction purposes although the application of bootstrap techniques to the empirical analysis of financial time series is very broad there are few analytical results on the statistical properties of these techniques when applied to heteroscedastic time series furthermore there are quite a few papers where the bootstrap procedures used are not adequate
