pricing multiasset equity options how relevant is the dependence function abstract in this paper we test how different choices for the dependence function can affect the prices of a set of multiasset equity options we conduct the analysis for various 5 dimensional baskets of uk shares and a wide range of payoffs for the multiasset options consistent with the instruments traded on the market we also test the relevance of the dependence specification over both volatile and quiet market scenarios interestingly we find that in most circumstances the choice of a dependence structure richer than the standard linear correlation does not seem to affect option prices substantially however the dependence function becomes more relevant in particularly volatile market conditions

estimating financial risk measures for options abstract this paper proposes a simulation lattice procedure to estimate financial risk measures for option positions the framework proposed can be applied to many different kinds of options including exotic and vanilla options it can take account of early exercise features heavy tails in underlying processes estimate different risk measures including var expected shortfall and spectral risk measures and in a limited way it can be generalized to accommodate multiple factors it avoids many of the limitations of existing approaches and in particular avoids the problems associated approaches based on delta gamma and similar approximations it also generates some interesting results about the risk measures of some illustrative options positions

modeling purchasing behavior with sudden death a flexible customer lifetime model this study proposes a new customer lifetime model the gamma gompertz distribution g g the advantage of this model relative to the well known pareto distribution is twofold i its probability density function can exhibit a mode at zero or an interior mode and ii it can be skewed to the right or to the left we combine the g g with a negative binomial distribution nbd and obtain the moments of the distribution of the number of transactions over 0 t and t t t out of six data sets the g g nbd model provides a notable improvement in the log likelihood over the pareto nbd model in four data sets it can indicate substantial differences in expected residual lifetimes compared to the pareto nbd and induce a retention rather than acquisition policy on the average the g g nbd exhibits slightly better forecasts of the mean number of transactions than the pareto nbd this paper was accepted by pradeep chintagunta marketing

an analysis of the true notional bond system applied to the cbot t bond futures abstract the conversion factor system cfs is used in the determination of the invoice price of the chicago board of trade treasury bond futures as an alternative to the cfs oviedo oviedo r a 2006 improving the design of treasury bond futures contracts the journal of business 79 1293 1315 proposed the true notional bond system tnbs and showed that it outperforms the cfs when interest rates are deterministic the main purpose of this paper is to compare the effectiveness of the two systems in a stochastic environment in order to do so we price the cbot t bond futures as well as all its embedded delivery options under both the cfs and the tnbs our pricing procedure is an adaptation of the dynamic programming algorithm described in ben abdallah et al ben abdallah r ben ameur h breton m 2007 pricing cbot treasury bond futures les cahiers du gerad g 2006 77 numerical illustrations show that in a stochastic framework tnbs does not always outperform the cfs however as the long term mean moves away from the level of the notional rate the tnbs performs increasingly better than the cfs

nonparametric conditional pricing of higher order multivariate contingent claims abstract this paper describes and applies a nonparametric model for pricing multivariate contingent claims multivariate contingent claims are contracts whose payoffs depend on the future prices of more than one underlying variable the pricing however of these kinds of contracts represents a challenge all known models are adaptations of earlier ones that have been introduced to price plain vanilla calls and puts they are imposing strong assumptions on the distributional properties of the underlying variables in contrast this study adopts a methodology that relaxes such restrictions following barone adesi g bourgoin f giannopoulos k 1998 don t look back risk 11 august 100 104 barone adesi g engle r mancini l 2004 garch options in incomplete markets mimeo university of applied sciences of southern switzerland long x 2004 semiparametric multivariate garch model mimeo university of california riverside multivariate pathways for a set of underlying variables are constructed before the option payoffs are computed this enables the covariances in addition to the means and variances to be modelled in a dynamic and nonparametric manner the model is particular suitable for options whose payoffs depend on variables that are characterised by high nonlinearities and extremes and on higher order multivariate options whose underlying variables are more unlikely to conform to a common theoretical distribution

learning by doing and the introduction of new goods a dynamic general equilibrium model is developed in which goods are valued according to the characteristics they contain the set of goods produced in any period is endogenously determined and learning by doing is the force behind sustained growth it is shown that the set of produced goods changes in a systematic way over time with goods of higher quality entering each period and those of lower quality dropping out the model is then used to study the effect of introducing a traditional sector in which there is no learning

a pricing method for options based on average asset values abstract in this paper we present a new strategy for pricing average value options i e options whose payoff depends on the average price of the underlying asset over a fixed period leading up to the maturity date such options are of particular interest and importance for thinly traded assets e g crude oil since price manipulation is inhibited and both the investor and issuer enjoy a welcome degree of protection from the vagaries of the market these options are often implicit in a bond contract although they also appear in a straightforward form our results suggest that the price of an average value option will always be lower than that of a standard european option our pricing strategy involves monte carlo simulation with variance reduction elements and offers an enhanced pricing method to both arbitragers and hedgers as well as to the issuers of such bonds

the sophistication of exports a new trade measure summary trade data are often classified by product characteristics we propose a new classification sophistication as a means of distinguishing between products we construct a sophistication index based on the income levels of exporting economies sophistication captures a range of factors including technology ease of product fragmentation natural resource availability and marketing we calculate sophistication scores at the 3 and 4 digit levels and test how far the index relates to existing technological classifications of products we use the index to examine trade patterns and illustrate how it can be applied in the analysis of export performance of individual economies

options on the minimum or the maximum of two risky assets analysis and applications this paper provides analytical formulas for european put and call options on the minimum or the maximum of two risky assets the properties of these formulas are discussed in detail options on the minimum or the maximum of two risky assets are useful to price a wide variety of contingent claims of interest to financial economists applications discussed in this paper include the valuation of foreign currency debt option bonds compensation plans risk sharing contracts secured debt and growth opportunities involving mutually exclusive investments

international market correlation and volatility international correlations for stocks and bonds fluctuate widely over time as previous studies have found volatility appears to be contagious across markets in addition international correlation increases in periods of high market volatility although the correlation of individual foreign stock markets with the u s stock market has generally increased slightly over the past 37 years it has not increased during the past 10 years similarly the international correlation of bond markets increased in the early 1980s but it has had no discernible trend in the past 10 years the fairly low levels of international correlation among stocks or bonds suggests that national factors still strongly affect local asset prices the link between correlation and market volatility is bad news for global money managers because when the domestic market is subject to a strong negative shock is when the benefits of international risk diversification are needed most

protection of property rights and growth as political equilibria abstract this paper presents a survey of the literature on property rights and economic growth different theoretical mechanisms that relate property rights to economic development are discussed lack of protection of property rights can result in slow economic growth through different channels expropriation of private wealth corruption of civil servants excessive taxation and barriers to adoption of new technologies the origins of property rights are also considered different theories are illustrated but more attention is paid to the social conflict view and its success and limitations the second part of the paper illustrates relevant empirical works on property rights and growth

learning matching and growth we examine an endogenous growth model in which market frictions are an integral part of the economic environment workers invest in education when young which raises their productivity onice employed the level of schooling also acts as a key determinant of the rate of economic growth by influencing workers ability to accumulate additional human capital on the job once schooling is completed workers search for employment the division of the surplus between vacancies and searching workers is characterized as is the optimal level of education the economy may display multiple steady state growth paths

information technology and the changing workplace in canada firm level evidence recent advances in information and communication technology ict have had dramatic effects on both individual and workplace performance use of computers and the internet as general purpose technologies has spread rapidly across all sectors of the economy transforming business organization increasing competition and fostering innovation understanding the influence of ict on the dynamics of the workplace requires information on both demand and supply sides of the labor market but it is only recently that the study of both sides of the market has become feasible using linked employer employee data in this article we investigate the effects of new technology on firm productivity using the rich canadian workplace and employee survey for the period 1999 2003 we apply a mixed regression model which includes both firm and employee characteristics as well as their interactions with computer use our model allows us to control for unobserved heterogeneity at higher levels along many dimensions our findings indicate that computer use by employees has a positive and significant effect on the productivity of firms that the effect has not lost its momentum and that spillover effects are not significant moreover human capital enhances the effect of computer use on productivity but organizational changes do not interact with computer use in our sample period copyright 2011 the author 2011 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

returns to scale productive efficiency and optimal firm size evidence from taiwan s firm data by using taiwan s census firm data this paper estimates and tests the variable returns to scale hypothesis for aggregate manufacturing and two digit industries an efficiency measure is constructed to further examine the size efficiency relations among two digit industries analysis indicates that increasing returns exist at the aggregate manufacturing level and its magnitude is higher for exporting firms than for non exporting firms moreover trade is beneficial only for small firms however the property of increasing returns diminishes for most of the industries at the two digit level particularly for the exporting firms this sharp comparison between aggregate and two digit level results suggests that trade is conducive to productivity and provides an indication of the specific form of technology spillovers among firms and across industries further investigation of the relationship between productive efficiency and firm size renders the result that optimal firm size is small for exporting firms i

effects of the preference for environmental quality on the export competition between china and oecd countries this study examines how importers preferences for environmentally friendly products influence the effect of china s export growth on the exports of oecd countries to third markets the effect of china s export growth is systematically investigated using the theoretical gravity model which assumes that importers environmental preferences are heterogeneous among countries a new measure is also proposed to represent importers revealed preferences for environmental quality across countries panel data consisting of observations for 30 oecd exporting countries and 60 importing countries over the 2000 10 period confirm that the crowding out effect of china s export growth on the exports of oecd countries observed in markets for consumption goods and the dampening effect observed in markets for intermediate goods are becoming weaker as the importer preference for environmental quality becomes stronger

ticking away the moments timing regularity helps to better predict customer activity accurate predictions of a customer s activity status and future purchase propensities are crucial for managing customer relationships this article extends the recency frequency paradigm of customer base analysis by integrating regularity in interpurchase timing in a modeling framework by definition regularity implies less variation in timing patterns and thus better predictability whereas most stochastic customer behavior models assume a poisson process of random purchase occurrence allowing for regularity in the purchase timings is beneficial in noncontractual settings because it improves inferences about customers latent activity status this especially applies to those valuable customers who were previously very frequently active but have recently exhibited a longer purchase hiatus a newly developed generalization of the well known pareto nbd model accounts for varying degrees of regularity across customers by replacing the nbd component with a mixture of gamma distributions labeled pareto gg

catch up in turn in a multi country international trade model with learning by doing and invention abstract we consider how the world income distribution evolves over time when both learning by doing and invention are the engines of economic growth and when countries interact with each other through international trade the main findings are i catch up is possible ii in the three country model transitional dynamics are much richer than in the two country model in particular catch up may occur in turn there may be a first stage in which the middle income country grows fastest closing the gap with the richest country but increasing the income difference with the poorest followed by a second stage where the poorest country catches up

the economics of product variety a survey demand for variety may arise from a taste for diversity in individual consumption and or from diversity in tastes even when each consumer chooses a single variant the full degree of variety potentially demanded will not in general be supplied because scale economies even to a small degree mean that the potential welfare or revenue gain from greater variety must be balanced against the lower unit production costs with fewer variants the economics of product variety consists essentially in analysing the effect of this balance in different situations and comparing the degree of product variety for different market structures with each other and with the optimum the survey commences with the work on market structures with single product firms generalized monopolistic competition tracing modern developments in both the chamberlinian and hotelling traditions the latter has been particularly fruitful due to the expansion of the original locational ideas into virtual spaces in product characteristics the emphasis in recent work on product variety has been on multiproduct firms in both monopolistic and oligopolistic structures including strategic market preemption although most work has been in a full information context there have been advances in product variety under imperfect information either by consumers to properties of the firms products or firms as to consumers demands

economic development as self discovery in the presence of uncertainty about what a country can be good at producing there can be great social value to discovering costs of domestic activities because such discoveries can be easily imitated we develop a general equilibrium framework for a small open economy to clarify the analytical and normative issues we highlight two failures of the laissez faire outcome there is too little investment and entrepreneurship ex ante and too much production diversification ex post optimal policy consists of counteracting these distortions to encourage investments in the modern sector ex ante but to rationalize production ex post we provide some informal evidence on the building blocks of our model

globalization and the skilled city abstract the location of economic activity both across and within countries has undergone dramatic shifts over the last five decades three key trends stand out first cross country inequality has declined as many developing countries have grown rapidly second economic geography within countries has instead grown more unequal in both the developed and the developing world third within country spatial disparities have grown mainly because of the disproportionate success of skilled cities in this paper i develop a model that jointly explains these patterns as a consequence of deepening international economic integration my model explains the faster population and output growth of skilled cities as well as their tendency to increase their initial skill advantage consistent with the evidence my theory predicts a non monotonic path of urban growth in developed countries the model predicts a future shift in worldwide urban hierarchies as some developing world cities overtake unskilled cities in industrialized countries along global supply chains

r d in a model of search and growth just how important a determinant of economic growth is the efficacy with which markets are organized it is clear that in order to answer this question it is necessary to have both a well articulated theory of economic growth and a precise notion of what it means for one market to be better organized than another the newly developed theory of endogenous growth pioneered by among others paul m romer 1986 robert e lucas 1988 nancy stokey 1988 and gene grossman and elhanan helpman 1991 has equipped economists with a rigorous microeconomic foundation of the growth process since its original inception research in this area has bifurcated one strand of work has continued to emphasize the importance of capital accumulation both physical and human in environments in which agents are competitive price takers the other strand has a distinctly neo schumpeterian flavor in which firms are price setters and purposive innovative activity leads to technological advancement but what of the role played by market organization the growth literature has remained relatively silent on this issue the reason is that the canonical growth model is one in which trade either competitive or monopolisticly competitive is coordinated by the walrasian auctioneer given that ex hypothesi trade is frictionless it is meaningless to use this framework to discuss issues pertaining to improvements in market organization however beginning with the seminal contributions of peter diamond 1982 dale t mortensen 1982 and christopher pissarides 1985 economists have begun to construct models that dispense with the auctioneer s coordinating function in this setting it is possible to make precise the notion of an improvement in market efficacy since search and bargaining frictions are explicitly incorporated as an integral part of the trading environment yet it is only very recently that this literature has begun to explore the consequences for perpetual economic growth

export sophistication and economic growth evidence from china we consider the effect of export sophistication on economic performance by appealing to regional variation within one single country china over the 1997 2009 period we find evidence in support of hausmann hwang and rodrik 2007 in that regions specializing in more sophisticated goods subsequently grow faster we find substantial variation in export sophistication at the province and prefecture level controlling for the level of development and that this sophistication in turn drives growth our results suggest that these gains are limited to the ordinary export activities undertaken by domestic firms no direct gains result from either processing trade activities or foreign firms even though these are the main contributors to the global upgrading of china s exports as such the extent of assembly trade and foreign entities should be distinguished in order to measure the true movement in a country s technology and the contribution of exports to economic growth

production experiences and market structure in r d competition abstract in the rd and ii the likelihood of persistent leadership increases with the value of being the winner and the value of being a loser but decreases with expected waiting time of r d innovation and the flow of monopoly profits however destructive innovations may still occur even when production experiences are allowed to play an important role in the r d competition

does aid for trade diversify the export structure of recipient countries the importance of aid for trade as a tool for facilitating trade economic growth and social development has received attention since the concept was introduced in 2005 while one of the main targets of aid for trade is export diversification reflecting the fact that the exports of many developing countries are concentrated in a small range of items there have not been many efforts to measure the effect of aid for trade on export structure this study therefore attempts to trace the relationship between aid for trade and 133 aid recipients export structure between 1996 and 2013 using the herfindahl hirschman index to measure the degree of export concentration the findings suggest that total aid for trade has reduced the concentration level in the short run in the long run on the other hand aid for trade has had no significant effect on export structure of recipient countries only aid for building productive capacity which is one of the three categories of aid for trade contributes to lower concentration yet this change is not caused by an increase in export diversity but by the redistribution of shares of existing products of a similar sophistication level

customer lifetime value measurement the measurement of customer lifetime value is important because it is used as a metric in evaluating decisions in the context of customer relationship management for a firm it is important to form some expectations as to the lifetime value of each customer at the time a customer starts doing business with the firm and at each purchase by the customer in this paper we use a hierarchical bayes approach to estimate the lifetime value of each customer at each purchase occasion by jointly modeling the purchase timing purchase amount and risk of defection from the firm for each customer the data come from a membership based direct marketing company where the times of each customer joining the membership and terminating it are known once these events happen in addition there is an uncertain relationship between customer lifetime and purchase behavior therefore longer customer lifetime does not necessarily imply higher customer lifetime value we compare the performance of our model with other models on a separate validation data set the models compared are the extended nbd pareto model the recency frequency and monetary value model two models nested in our proposed model and a heuristic model that takes the average customer lifetime the average interpurchase time and the average dollar purchase amount observed in our estimation sample and uses them to predict the present value of future customer revenues at each purchase occasion in our hold out sample the results show that our model performs better than all the other models compared both at predicting customer lifetime value and in targeting valuable customers the results also show that longer interpurchase times are associated with larger purchase amounts and a greater risk of leaving the firm both male and female customers seem to have similar interpurchase time intervals and risk of leaving however female customers spend less compared with male customers

has latin america s post reform growth been disappointing after years of poor economic performance many latin american countries undertook ambitious programs of macroeconomic stabilization and structural reform in recent years this change in policy created high expectations for the region and some observers have questioned whether actual growth outcomes have lived up to these expectations the authors offer evidence that the response of economic growth to reforms in latin america has not been disappointing because of their significant policy changes and despite a global slowdown latin america did well to return to its historic growth rate of 2 percent per capita in 1990 93 latin america has responded to changes in policy variables as would have been predicted by the experience of other times and places those earlier experiences are summarized by a panel regression spanning many countries and multi year periods from 1960 to 1993 to get consistent estimates of the parameters linking growth and policy variables the authors use a dynamic panel methodology that both controls for unobserved time and country specific effects and accounts for the likely internal dynamism of the explanatory variables

an overlapping generations model of growth and the environment this article analyzes the potential conflict between economic growth and the maintenance of environmental quality in an overlapping generations model short lived individuals make decisions which have long lasting effects on both factor productivity and the environment the model provides a theoretical explanation of observed correlations between environmental quality and income whereby economic growth is associated first with declines then improvements in environmental quality it suggests circumstances in which multiple pareto ranked steady state equilibria may arise and in which sustained growth of both capital and environmental quality may occur overmaintenance of the environment analogous to dynamically inefficient overaccumulation of capital may emerge copyright 1994 by royal economic society
