price search and periodic price discounts this paper empirically investigates the interplay between buyer search behavior and firm pricing strategy in a commodity market where many firms compete in price to sell homogeneous products we use the heterogeneity in buyer search cost to rationalize why a firm offers periodic price discounts and enjoys a high profit in such a market an estimation method is proposed to recover the nonparametric distribution of buyer search cost from the price and transaction volume data with both data we show that the search cost distribution can be estimated nonparametrically in a sequential search model and estimation results from a nonsequential search model are robust to the assumption on the maximum number of searches we also show that the commonly observed high low pricing strategy can be an optimal strategy for firms when buyers search for price information sequentially as an empirical application we use the proposed method to estimate the two search models using data on a commodity product sold by a firm

wage and technology dispersion this paper explains why firms with identical opportunities may use different technologies and offer different wages our key assumption is that workers must engage in costly search in order to gather information about jobs stigler 1961 in equilibrium some firms adopt high fixed cost high productivity technologies offer high wages and fill job openings quickly other firms adopt less capital intensive technologies and offer low wages hiring mostly uninformed workers in equilibrium the amount of wage dispersion leaves workers indifferent about whether to gather information and the fraction of informed workers leaves firms indifferent about their wage and technology choice we show that worker search which would appear to be a rent seeking activity in partial equilibrium may be efficiency enhancing in general equilibrium

does decentralization contribute to efficiency evidence from oecd countries abstractthis article provides evidence on the relationship between fiscal decentralization and technical efficiency we begin the first stage of this study with a data envelopment analysis to obtain technical efficiency estimates for a sample of 23 oecd countries over the period 1992 2009 in a second stage we explore the effects of fiscal decentralization and other control variables on technical efficiency the results including all the control variables reveal a statistically significant negative relationship between fiscal decentralization of public expenditure and technical efficiency

pitfalls in the use of systemic risk measures we examine pitfalls in the use of return based measures of systemic risk contributions srcs for both linear and nonlinear return frameworks assuming normal and heavy tailed distributions we identify nonexotic cases in which a change in a bank s systematic risk idiosyncratic risk size or contagiousness increases the risk of the system but lowers the measured src of the bank assessments based on estimated srcs could thus produce false interpretations and incentives we also identify potentially adverse side effects a change in a bank s risk structure can make the measured src of its competitors increase more strongly than its own

the long term role of non traditional banking in profitability and risk profiles evidence from a panel of u s banking institutions abstract the goal of this empirical study is to identify empirically and on a panel basis how non traditional bank activities affect directly the profitability and risk profiles of the financial institutions involved in such activities through a dataset that covers 1725 u s financial institutions involved in non traditional bank activities spanning the period 2000 2013 and the methodology of panel cointegration the empirical findings document that non traditional bank activities exert a positive effect on both the profitability and the insolvency risk the results could be important for regulators given they could serve as a pre warning signal that sends a clear message to regulators about the potential systemic risk that exists within the financial markets

this time is the same using bank performance in 1998 to explain bank performance during the recent financial crisis are some banks prone to perform poorly during crises if yes why in this paper we show that a bank s stock return performance during the 1998 crisis predicts its stock return performance and probability of failure during the recent financial crisis this effect is economically large our findings are consistent with persistence in a bank s risk culture and or aspects of its business model that make its performance sensitive to crises banks that relied more on short term funding had more leverage and grew more are more likely to be banks that performed poorly in both crises

using price distributions to estimate search costs we show how the equilibrium restrictions implied by standard search models can be used to estimate search cost distributions using price data alone we consider both sequential and nonsequential search strategies and develop estimation methodologies that exploit equilibrium restrictions to recover estimates of search cost heterogeneity that are theoretically consistent with the search models we illustrate the method using online prices for several economics and statistics textbooks

discrete equilibrium price dispersion an explicit solution of an equilibrium model with price setting firms and searching customers makes possible a number of comparativestatics predictions about how cost differences among firms search costs of customers and taxes will affect the mean and variance of the distribution of market prices another implication of the model is that a firm s demand depends on the difference between its price and the average price in the market

maximum likelihood estimation of search costs abstract in a recent paper hong and shum 2006 using price distributions to estimate search costs rand journal of economics 37 257 275 present a structural method to estimate search cost distributions we extend their approach to the case of oligopoly and present a new maximum likelihood method to estimate search costs we apply our method to a data set of online prices for different computer memory chips the estimates suggest that the consumer population can be roughly split into two groups which either have quite high or quite low search costs search frictions confer a significant amount of market power to the firms despite more than 20 firms operating in each of the markets we estimate price cost margins to be around 25 the paper also illustrates how the structural method can be employed to simulate the effects of the introduction of a sales tax

diversification in banking is noninterest income the answer this paper assesses potential diversification benefits in the u s banking industry from the steady shift toward activities that generate fee income trading revenue and other types of noninterest income in the aggregate declining volatility of net operating revenue reflects reduced volatility of net interest income not diversification benefits from noninterest income which is quite volatile and increasingly correlated with net interest income at the bank level greater reliance on noninterest income particularly trading revenue is associated with lower risk adjusted profits and higher risk this suggests few obvious diversification benefits from the ongoing shift toward noninterest income

multiproduct equilibrium price dispersion abstract the model of burdett and judd econometrica51 1993 955 969 is generalized to the case of may goods consumers choose the best price observed for each good there are two classes of equilibria those that involve constant expected profits for each good independently of price and those with increasing profits for each good in price a continuum of the latter type always exists these equilibria are qualitatively different than the unique equilibrium of the single good case journal of economic literature classification numbers d83 d43 l13

price dispersion in the small and in the large evidence from an internet price comparison site this paper examines four million daily price observations for more than 1 000 consumer electronics products on the price comparison site http shopper com we find little support for the notion that prices on the internet are converging to the law of one price in addition observed levels of price dispersion vary systematically with the number of firms listing prices the difference between the two lowest prices the gap averages 23 per cent when two firms list prices and falls to 3 5 per cent in markets where 17 firms list prices these empirical results are an implication of a general clearinghouse model of equilibrium price dispersion

srisk a conditional capital shortfall measure of systemic risk we introduce srisk to measure the systemic risk contribution of a financial firm srisk measures the capital shortfall of a firm conditional on a severe market decline and is a function of its size leverage and risk we use the measure to study top financial institutions in the recent financial crisis srisk delivers useful rankings of systemic institutions at various stages of the crisis and identifies fannie mae freddie mac morgan stanley bear stearns and lehman brothers as top contributors as early as 2005 q1 moreover aggregate srisk provides early warning signals of distress in indicators of real activity received june 7 2011 accepted april 18 2016 by editor geert bekaert

fiscal federalism and economic growth this paper uses an endogenous growth model with overlapping generations to explore the connection between fiscal federalism and economic growth the analysis shows that federalism which allows public good levels to be tailored to suit the differing demands of young and old consumers who live in different jurisdictions increases the incentive to save this stronger incentive in turn leads to an increase in investment in human capital and a byproduct of this higher investment is faster economic growth

search and price dispersion in online grocery markets abstract consumers often purchase multiple products at a time from retailers creating multi product incentives for search in this paper we consider how product variety affects consumer search intensity and the dispersion of prices in multi product retail markets we employ online grocery pricing data from four large retailers in the uk to estimate search costs and equilibrium price dispersion for food products under circumstances where i consumers search for single products and ii consumers search for multiple products at once we compare estimates in each case between a model in which utility increases with product variety and a model in which utility is not a function of variety relative to our preferred specification with variety effects in utility we find estimates of both search cost and search frequency to be biased upwards in single product settings when variety effects are ignored however we find estimates of search costs are biased upwards while search frequency is biased downwards in multi product settings when variety effects in utility are ignored

equilibrium with product differentiation tive consumer formulations is used to examine the properties of single and multiple price equilibria conditions under which decreases in the intensity of consumer preferences reduce price are given it is shown that with certain types of demand curves entry can eliminate price cost markups even given product differentiation if competition is localized it is demonstrated that entry does not affect the markup finally the effect of spurious product differentiation on price is examined

does deposit insurance increase banking system stability an empirical investigation based on evidence of 61 countries in 1980 97 the authors find that explicit deposit insurance tends to be detrimental to bank stability the more so where bank interest rates are deregulated and the institutional environment is weak the adverse impact of deposit insurance on bank stability tends to be stronger the more extensive is the coverage offered to depositors and where the scheme is funded and run by the government rather than the private sector

price increasing competition in a discrete choice model of product differentiation the symmetric duopoly price may be lower than equal to or higher than the single product monopoly price whereas the market share effect encourages a duopolist to charge less than the monopoly price because a duopolist serves fewer consumers the price sensitivity effect motivates a higher price when more consumer choice steepens the firm s demand curve the joint distribution of consumer values for the two conceivable products determines the relative strength of these effects the analysis provides precise conditions for price increasing competition and reveals that it is unexceptional from a theoretical perspective

number of sellers average prices and price dispersion abstract a variety of models provide differing predictions regarding the effect of an increase in the number of competitors in a market seller density on prices and price dispersion we review different approaches to generating equilibrium price dispersion and then empirically estimate the relationship between seller density average product price and price dispersion in the retail gasoline industry using four unique gasoline price data sets controlling for station level characteristics we find that an increase in station density consistently decreases both price levels and price dispersion across four geographical areas

does tax competition really promote growth abstract this paper considers the relationship between tax competition and growth in an endogenous growth model where there are stochastic shocks to productivity and capital taxes fund a public good which may be for final consumption or an infrastructure input absent stochastic shocks decentralized tax setting two or more jurisdictions maximizes the rate of growth as the constant returns to scale present with endogenous growth implies extreme tax competition stochastic shocks imply that households face a portfolio choice problem which dampens down tax competition and may raise taxes above the centralized level growth can be lower with decentralization our results also predict a negative relationship between output volatility and growth with decentralization

existence and persistence of price dispersion an empirical analysis the hebrew university of jerusalem and nber using a unique data set on store level monthly prices of four homogenous products sold in israel i study the existence and characteristics of the dispersion of prices across stores as well as its persistence over time i find that price dispersion prevails even after controlling for observed and unobserved product heterogeneity moreover intra distribution mobility is significant stores move up and down the cross sectional price distribution thus consumers cannot learn about stores that consistently post low prices as a consequence price dispersion does not disappear and persists over time as predicted by varian s 1980 model of sales

price cycles and booms dynamic search equilibrium search theory has been extensively and successfully applied to explain the persistence of price dispersion this paper presents an explicitly dynamic search model that is able to account for cyclical patterns of prices and demand over time these cyclical features of the model are the consequence of the dynamic strategic interaction between buyers and firms and do not require the presence of extraneous factors such as shocks or heterogeneity of agents in order to obtain the model builds on earlier work by kenneth burdett and kenneth l judd and may be interpreted as a dynamic extension of their model copyright 1992 by american economic association

fiscal decentralization and economic growth abstract fiscal decentralization may indeed have a direct impact on economic growth but the theoretical underpinnings for this relationship remain largely undeveloped a fair summary of the empirical search for a direct relationship between fiscal decentralization and economic growth is that it remains an open question much less attention has been devoted in the literature to the indirect channels through which fiscal decentralization may affect economic growth we argue that much work remains to be done before policy advisors and decision makers can formulate and implement decentralization programs on the basis of improving the rate of economic growth

nonsequential search equilibrium with search cost heterogeneity we generalize the model of burdett and judd 1983 to the case where an arbitrary finite number of firms sells a homogeneous good to buyers who have heterogeneous search costs we show that a price dispersed symmetric nash equilibrium always exists numerical results show that the behavior of prices and consumer surplus with respect to the number of firms hinges upon the nature of search cost dispersion when search costs are relatively concentrated entry of firms leads to lower average prices and greater consumer surplus however for relatively dispersed search costs the mean price goes up and consumer surplus may decrease with the number of firms

oligopolistic pricing with sequential consumer search n identical stores compete by choosing prices for a homogeneous good with constant marginal costs consumers search sequentially with perfect recall for the lowest price one class of consumers called shoppers have zero search costs while all other consumers have a positive search cost c there is a unique symmetric nash equilibrium price distribution with the property that it changes smoothly from marginal cost pricing when all consumers are shoppers and or c 0 and monopoly pricing when no consumers are shoppers remarkably as the number of stores increases the nash equilibrium becomes more monopolistic copyright 1989 by american economic association

fiscal decentralization and economic growth reconsidered recent studies examining the relation between fiscal decentralization and economic growth have failed to take account of the extent of the independent taxing powers available to sub national governments and thus have substantially overstated the degree of effective decentralization results from a cross section study of 19 oecd member countries suggest that when the measure of fiscal decentralization is limited to the revenues over which sub national governments have full autonomy its impact on economic growth is not statistically significant

regional economic disparities and decentralisation the study of the influence of decentralisation on economic growth has received some attention in recent years but very few studies deal with its impact on regional inequalities this paper analyses the impact of both fiscal and political decentralisation on regional inequalities using alternative measures for a sample of 17 oecd countries in order to check for other possible influences the study also includes measures of public sector size and the type of party in government the final section studies the relevance of fiscal decentralisation in the regional convergence process observed by several authors during the past two decades the research reveals a strong negative correlation between decentralisation especially fiscal decentralisation and regional inequalities and also a positive influence of decentralisation on regional convergence

prices and heterogeneous search costs we study price formation in a model of consumer search for differentiated products in which consumers have heterogeneous search costs we provide conditions under which a pure strategy symmetric nash equilibrium exists and is unique search costs affect two margins the intensive search margin or search intensity and the extensive search margin or the decision to search rather than to not search at all these two margins affect the elasticity of demand in opposite directions and whether lower search costs result in higher or lower prices depends on the properties of the search cost density

federal competition and economic growth abstract this paper exploits exogenous variation in the natural topography of the united states to estimate the causal impact of inter jurisdictional competition on income growth we find that doubling the number of county governments in a metropolitan area leads to a 17 increase in the average annual growth rate of earnings per employee over 1969 2006 and a 10 increase in 2006 income per employee decomposing income effects using 2000 census worker level data we find that approximately half of the effect stems from making workers more productive while the other half comes from changing the composition of the workforce and inducing workers to work more hours we also present evidence that inter jurisdictional competition leads local governments to raise more in taxes spend more and issue more debt per capita but does not help them obtain more inter governmental transfers however the additional cost from this increase in expenditures to a median wage employee is much smaller than the increase in that employee s wages due to greater inter jurisdictional competition

aid growth and devolution considering aid modality and different types of decentralization in this paper we provide further evidence on the relationship between decentralization and foreign aid effectiveness our previous work has shown that decentralization decreases aid effectiveness i e the impact of aid on economic growth is negative in decentralized countries however our previous work has not taken different types of aid and different types of decentralization into account which is at the heart of our current analysis we consider different measures of decentralization in particular measures of fiscal decentralization derived from government finance statistics and measures of political decentralization that are constructed based on countries constitutional rules in addition we take different types of aid into account grants loans technical assistance total net oda and we distinguish between multi lateral and bi lateral aid in order to consider differences in the donor structure our empirical analysis is based on panel data of up to 53 developing countries in our growth regressions we combine all types of decentralization with the different types of aid we find important differences between different types of decentralization i fiscal decentralization negatively affects aid effectiveness in line with our previous work ii employment decentralization may increase aid effectiveness and iii political decentralization does not hamper aid effectiveness or may even have positive effects

semi nonparametric estimation of consumer search costs this paper studies the estimation of the distribution of non sequential search costs we show that the search cost distribution is identified by combining data from multiple markets with common search technology but varying consumer valuations firms costs and numbers of competitors to exploit such data optimally we provide a new method based on semi nonparametric estimation we apply our method to a dataset of online prices for memory chips and find that the search cost density is essentially bimodal such that a large fraction of consumers searches very little whereas a smaller fraction searches a relatively large number of stores copyright c 2012 john wiley sons ltd

price dispersion and competition with differentiated sellers i measure price dispersion among differentiated retail gasoline sellers and study the relationship between dispersion and the local competitive environment significant price dispersion exists even after controlling for differences in station characteristics and price differences between sellers change frequently the extent of price dispersion is related to the density of local competition but this relationship varies significantly depending on the type of seller and the composition of its competitors these findings are consistent with interactions between seller and consumer heterogeneity that are not well understood in the existing price dispersion literature

equilibrium price dispersion in retail markets for prescription drugs this study seeks to establish the empirical importance of price dispersion due to costly consumer search by examining retail prices for prescription drugs posted prices in two geographically distinct markets are shown to vary considerably across pharmacies within the same market even after one controls for variation due to pharmacy differences pharmacy heterogeneity accounts for at most one third of the observed price dispersion the empirical analysis hinges on the observation that consumers incentives to price shop depend on characteristics of the drug therapy cross sectional patterns in price distributions across drugs are consistent with the predictions of a search model prices for repeatedly purchased prescriptions for which the expected benefits of search are highest exhibit significant reductions in both dispersion and price cost margins

fiscal decentralisation and idc economic growth an empirical investigation the impact of fiscal decentralisation on ldc economic growth and development is widely debated in the development literature notwithstanding this there has been little attempt to test systematically this relationship accordingly in this note we present an empirical examination of the relationship between the level of fiscal decentralisation and economic growth rates across a sample of twenty three ldcsfrom 1974 to 1991 we fail to find however any strong systematic relationship between the two among our sample of ldcs

an empirical model of search with vertically differentiated products this paper presents a nonsequential search model that allows for vertical product dierentiation in the unique symmetric equilibrium firms with dierent characteristics draw utilities from a common utility distribution because the firms dier in their characteristics this leads to dierent price distributions the model therefore provides a theoretical rationale for explaining price dispersion as a result of quality dierences and search behavior of consumers together using the equilibrium conditions derived from the model it is shown how to estimate search costs by maximum likelihood using only price data a data set on prices from dutch supermarkets reveals that the amount of search has decreased over the sampling period moreover ignoring vertical product dierentiation results in an overestimation of search costs

strategic pricing consumer search and the number of firms discover prices there are three distinct price dispersed equilibria characterized by low moderate and high search intensity the effects of an increase in the number of firms on search behaviour expected prices price dispersion and welfare are sensitive i to the equilibrium consumers search intensity and ii to the status quo number of firms for instance when consumers search with low intensity an increase in the number of firms reduces search does not affect expected price leads to greater price dispersion and reduces welfare in contrast when consumers search with high intensity increased competition results in more search and lower prices when the number of competitors in the market is low to begin with but in less search and higher prices when the number of competitors is large duopoly yields identical expected price and price dispersion but higher welfare than an infinite number of firms a question that has received much attention in economic theory is how the number of competitors and market outcomes are related despite the existence of work showing the contrary see e g satterthwaite 1979 rosenthal 1980 the prediction that emerges from a market where firms interact in a cournot fashion has come to dominate economic thought namely that an increase in the number of competitors leads to larger aggregate production lower market price and improved market performance measured in terms of some social welfare criterion ruffin 1971 this paper challenges the generality of this belief by presenting an oligopoly model with consumer search where the equilibrium expected price may be constant increasing or nonmonotonic in the number of firms we present an economy with two types of consumers consumers who search for prices at no cost fully informed and consumers who must pay a fixed search cost for each price quotation they observe less informed 1 all buyers have the same willingness to pay for the good and buy either a single unit or nothing at all on the supply side of the market there are n firms producing a homogeneous good at constant marginal cost we analyse a one shot simultaneous move game firms set prices and consumers decide how many prices to search for at the same moment in time our model is essentially an oligopolistic version of burdett and judd 1983 where some consumers search costlessly in this model consumers search using a fixed sample size search strategy i e they choose the number of prices to observe before receiving any offer nonsequential search is appealing when consumers find it more advantageous to gather price information quickly morgan and manning 1985 this occurs when the search outcome is observed with delay and delay is costly for instance an mba graduate looking for a job 1 the presence in the model of consumers who search costlessly captures the fact that some people have a

pricing product diversity and search costs a bertrand chamberlin diamond model we study price competition in the presence of search costs and product differentiation the limit cases of the model are the bertrand paradox the diamond paradox and chamberlinian monopolistic competition market prices rise with search costs and decrease with the number of firms prices may initially fall with the degree of product differentiation because more diversity leads to more search and more competition equilibrium diversity rises with search costs while the optimum level falls so entry is excessive the market failure is most pronounced for low preference for variety and high search costs

on the riskiness of universal banking evidence from banks in the investment banking business pre and post glba we explore whether an economically significant differential exists in market based risk measures between universal banks and traditional banks using a three asset portfolio regression model we find that between 1990 and 2007 a period of gradual deregulation culminating in passage of the gramm leach bliley act glba of 1999 an increased participation in investment banking was associated with higher total and unsystematic risks and no significant change in systematic risk small risk reduction benefits emerged in the post glba era but such benefits were likely the result of the particular sample period rather than a fundamental change in bank structure following the glba our results cannot justify the glba on risk reduction grounds though the act may be defensible for other reasons

the impact of fiscal decentralization on the composition of public expenditure panel data evidence from italy grisorio m j and prota f the impact of fiscal decentralization on the composition of public expenditure panel data evidence from italy regional studies this paper is an original contribution to the understanding of the relationship between fiscal decentralization and public expenditure composition it studies the effects of the ongoing decentralization process in italy on the share of different categories of public spending in total expenditure of the italian regional administrations over the period 1996 2008 the data used allow one to go beyond the usual distinction between current and capital expenditures and to present a functional classification of public expenditures through a panel data analysis the paper shows that the level of decentralization influences the composition of expenditure

price price dispersion and number of sellers at a low entry cost shopbot abstract shopbots function as market intermediaries by providing unprecedented quantities of information to buyers and sellers this paper explores the role of market structure across shopbot mediated markets using an unbalanced panel of 399 digital camera models it extends prior work by using an ultra low entry cost site additionally allowing controls for life cycle and popularity effects we find a robust negative relationship between seller number and price which persists even as markets become crowded with sellers the results are capable of either an scp or a carlson mcafee heterogeneous cost interpretation but observed entry behaviour here is consistent with the latter

the impact of fiscal decentralization on economics performance in high income oecd nations an institutional approach this paper examines the impact of public sector decentralization on per capita income controlling for differences in institutional arrangements among countries panel data regressions on a sample of observations from 20 high income oecd nations spanning the years 1972 to 2005 indicate that decentralization is positively related to income the empirical analysis shows that institutions consistent with economic freedom enhance the positive income effects of decentralization thus the impact of public sector decentralization is dependent upon a nation s institutional environment

fiscal federalism decentralization and economic growth a meta analysis the theoretical literature on fiscal federalism has identified several channels through which government decentralization could affect economic growth much of the literature focuses on the efficiency aspects of a decentralized provision of public services but decentralization may also increase growth by raising the ability of the political system to innovate and carry out reforms in contrast some authors argue that decentralization increases corruption and government inefficiency and thus may diminish growth given this theoretical ambiguity several studies have attempted to identify the effect of decentralization on economic growth empirically over the last two decades we review and conduct a meta analysis of this empirical literature based on our analysis we point out open questions and discuss possible ways to answer them jel h77 043 c52 i introduction building on various theoretical contributions an empirical literature analyzing the effect of fiscal decentralization on economic growth has emerged since the 1990s the relevant studies vary as to whether they use cross sectional time series or panel data as to whether they rely on cross country or single country samples and they vary in estimation methods decentralization measures and sample composition given the size and heterogeneity of the empirical literature it is useful to review the individual studies and summarize their main findings conducting a comprehensive search we identify 31 published and unpublished studies on the effect of fiscal decentralization on economic growth each of these studies estimates several models resulting in over 400 individual estimates while we first review these studies in a traditional manner our main aim is to analyze these estimates quantitatively specifically the main contribution of this article is to offer a meta analysis of the empirical findings on fiscal decentralization and economic growth a meta analysis is a useful methodology in our context as it is difficult to obtain clear cut conclusions with only a traditional survey of empirical literature the individual studies vary substantially in their characteristics and correspondingly in the findings they report by conducting a meta analysis however we can identify how the idiosyncratic characteristics of a particular study relate to its findings the meta analysis approach thus addresses model uncertainty with regard to each individual estimate in addition it can also serve as a partial response to the methodological critique of empirical research on fiscal decentralization by rodden 2004 as it helps to clarify the quantitative effects of different decentralization measures and estimation techniques finally as meta analytical techniques are rarely used in economics we also aim at contributing to the further establishment of this methodology stanley 2001 2008 the next section briefly discusses the various theoretical arguments as to why fiscal decentralization may affect economic growth we then provide a short traditional survey of the empirical studies in section iii we review this literature more systematically and quantitatively in section iv in section v we report the results of meta regressions and discuss how the idiosyncratic characteristics of a given study are related to its specific findings finally section vi provides a discussion of the results and some conclusions ii how could fiscal federalism affect economic growth theoretical approaches within the framework of the solow swan model solow 1956 swan 1956 fiscal federalism may be associated with a different level of efficiency in governance than unitary systems leading to a different value of solow s a the level of technology a regime change toward federalism would then be associated with temporarily different growth rates and eventually different levels of income but not with persistent growth differences

valuation of diversified banks new evidence abstract this paper reconsiders the effect of diversification on bank valuation our objective is to provide new evidence based on a unified estimation framework that places particular emphasis on separating the effects of diversification specialised banks vs diversified banks from those of bank type investment banks vs commercial banks consistent with prior studies we find a significant diversification discount at the end of the 1990s our main finding is that it decreases over time and practically vanishes after the financial crisis we do not find support for the hypothesis that the diversification effect is influenced by geographical or regulatory factors the valuation impact of bank characteristics varies over time particularly in the financial crisis but this structural break does not explain the observed decrease of the diversification discount we show that the pre crisis discount is considerably smaller in a robust regression which in part is driven by banks with a large share of non interest income

do financial conglomerates create or destroy value evidence for the eu there is an ongoing debate about whether firm focus creates or destroys shareholder value earlier literature has shown significant diversification discounts firms that engage in multiple activities are valued lower various factors are important in determining the size of the discount for example cross subsidization and agency problems the existing literature however generally focuses on non financial firms or on banks combining investment and commercial banking our paper focuses specifically on the valuation of bank insurance conglomerates we find no universal diversification discount but significant variability the discount is explained by the size increasing the familiarity with the conglomerate business model decreasing and the risk profile decreasing our results are robust to the historical origin the merger record and the age of the conglomerate as well as peer group specification and outlier elimination

does uniqueness in banking matter abstract we investigate whether and how the uniqueness of banking activities affects the performance and systemic risk of u s banks we find that banks performing more unique activities exhibit higher profitability and lower risk controlling for size diversification and other key characteristics we further find that banks sensitivity to systemic risk displays an inversely u shaped relation with activity uniqueness we interpret the impact of uniqueness in analogy to recent theories showing that systemic diversity promotes financial stability our study highlights the role of uniqueness in banking and has important implications for policy makers and banking regulators

aid growth and devolution summary this paper examines whether the degree of fiscal decentralization in aid receiving countries matters in explaining aid effectiveness the decentralization theorem predicts that the devolution of powers should increase aid effectiveness since local decision makers are better informed about local needs thereby decentralization may also have reverse effects e g through coordination problems excessive regulation administrative costs and local capture we use panel data for up to 60 countries and find that aid contributes to economic growth in centralized developing economies whereas it is less effective or even harmful in decentralized countries the cases of indonesia the philippines and uganda support our findings our results imply that donor countries should carefully consider how the two development instruments foreign aid and decentralization interact

fiscal decentralization and economic growth in the oecd what impact if any does fiscal decentralization fd have on economic growth further investigations of the inter relationships between fd and economic growth are timely given that government decentralization remains at the forefront of many organization for economic cooperation and development oecd policy agendas this study incorporates a range of measures of fd to better account for the direct impact of different levels of subnational fiscal autonomy on economic growth the analysis also considers the impact of previously omitted public sector decentralization variables that provide further indication of the extent to which subnational governments sng are closer to the people and potentially better able to account for local preferences in fiscal decision making whilst little evidence of a direct relationship between fd and output growth is found some evidence is found to suggest that federal systems tend to have lower growth rates than do unitary states independent of their degree of decentr

services and the business models of product firms an empirical analysis of the software industry some product firms increasingly rely on service revenues as part of their business models one possible explanation is that they turn to services to generate additional profits when their product industries mature and product revenues and profits decline we explore this assumption by examining the role of services in the financial performance of firms in the prepackaged software products industry standard industrial classification code 7372 from 1990 to 2006 we find a convex nonlinear relationship between a product firm s fraction of total sales coming from services and its overall operating margins as expected firms with a very high level of product sales are most profitable and rising services are associated with declining profitability we find however that additional services start to have a positive marginal effect on the firm s overall profits when services reach a majority of a product firm s sales we show that traditional industry maturity arguments cannot fully explain our data it is likely that changes in both strategy and the business environment lead product firms to place more emphasis on services this paper was accepted by christoph loch r d and product development
