valuing nuclear energy risk evidence from the impact of the fukushima crisis on u s house prices abstract behavioral economics suggests that individuals overweight recent unexpected and or rare events when updating beliefs this study investigates the effect of such an event the fukushima nuclear crisis in 2011 on the learning process of a local environmental risk by evaluating how perceptions of the risk of a nuclear accident are capitalized into house prices near nuclear power plants npps in the u s our results provide new evidence on the dynamics of the effect spatially the impact was concentrated in a 4 km radius around npps and temporally it peaked a half year later and dissipated one year after the crisis

the intertemporal stability of the concentration margins relationship using a longitudinal data base we find that there has been a substantial narrowing of the spread between the price cost margins of concentrated and unconcentrated industries including measures of macroeconomic fluctuations into standard price cost margin regressions we find significant differences in cyclical behavior across market structure we also explore a possible explanation unionization for differences in cyclical behavior finally we investigate the degree to which our results are affected by the potential simultaneity of concentration advertising and the price cost margin

advertising concentration and profitability in manufacturing advertising concentration and profitability in manufacturing i introduction economists have devoted much effort to empirically testing the hypothesized relationships between industrial concentration profits and advertising twenty years ago lester telser concluded that there is little empirical support for an inverse association between advertising and competition 1964 later other economists studying the relationship between advertising and concentration discovered a positive correlation between the four firm concentration ratio a measure of industry concentration and advertising intensity 1 strickland and weiss 1976 went further to show that there is a causal relationship between these elements increases in concentration cause advertising to intensify and conversely a rise in advertising intensity causes an increase in the level of concentration in recent years the empirical literature on advertising concentration and profitability has atrophied because of dissatisfaction with its theoretical basis as a new approach i adopt the theory of advertising developed by stigler and becker 1977 and extend it to incorporate the relationships among advertising concentration and profitability i then test its most important implications using data from the 1977 census of manufactures and the detailed input output structure of the u s economy 2 section ii examines the relationship between concentration and advertising intensity conventional theory known as the inverted u hypothesis asserts that advertising is expected to increase with concentration at first but to decrease at very high levels of concentration because collusion to avoid advertising costs becomes easier extending the stigler and becker theory i hypothesize that when concentration increases even if the large firms do not collude and continue to act independently they will eventually decrease their advertising intensity at high levels of concentration provided that the demand curve for the industry s products is relatively inelastic if the industry s demand curve is relatively elastic advertising intensity increases monotonically with concentration at all levels of concentration this hypothesis is supported by the 1977 data taken from the census and the input output structure of the u s economy section iii focuses on the relationship between advertising and profitability according to conventional theories advertising intensity promotes product differentiation leading to higher barriers to entry and higher profit margins in the past researchers e g strickland and weiss 1976 realized that contrary to the implications of barriers to entry theory the coefficient of advertising in a profit margin equation was longer for a sample of industries producing producer goods than for industries producing consumer goods they viewed this result as an anomaly inconsistent with both their theoretical reasoning and with other important empirical results already published i obtain a similar result which i am able to link to a theoretical structure thus contributing to the refutation of the barriers to entry hypothesis i begin by extending the stigler and becker theory to treat advertising and research and development r d as two complementary intangible capital goods the sample is divided into two groups producers of homogeneous goods who spend relatively more on r d and producers of heterogeneous goods who spend relatively more on advertising since we are unable to measure r d costs at the appropriate industry level it is not included among the regression variables if r d and advertising intensity are correlated we should expect the coefficient of advertising in the profitability equation in the homogeneous goods subsample to exceed the coefficient of advertising in the profitability equation in the heterogeneous goods subsample in this case the omission of the r d variable provides an implication for testing the new hypothesis

quasi experimental evidence on the effect of aircraft noise on apartment rents inferring the implicit price of an environmental good hinges on ceteris paribus conditions that are often hard to justify this paper uses an unexpected change in flight regulations as source of exogenous variation and identifies aircraft noise effects from price adjustments in the market for rental apartments controlling for spatial and apartment heterogeneity we find that aircraft noise reduces apartment rents by about 0 5 per decibel our results indicate i that noise discounts are overestimated in cross sectional studies because aircraft noise tends to be negatively correlated with omitted neighborhood and housing amenities and ii that noise effects are unlikely to be constant over the entire noise range

technological regimes catching up and leapfrogging findings from the korean industries abstract this paper examines the experiences of selected industries in korea to identify the stylized facts in the process of technological capability building and thereby to sort out the conditions for the catching up to occur to explain the process we have built a model of technological and market catching up a special attention has been given to the question of whether there has been a case of leapfrogging in any industry in korea and if so what are the conditions for its incidence in our framework we first measure the degree of catching up in terms of market shares in the world then we focus on catching up in technological capabilities in explaining the different record and prospects of korean industries in market catching up in the model technological capability is determined as a function of both technological effort and the existing knowledge base as determinants of technological effort we look at the technological regimes of the industries such as cumulativeness of technical advances fluidity predictability of technological trajectory and the properties of knowledge base using this model we explain the different technological evolution of the selected industries in korea including the d ram automobile mobile phone consumer electronics personal computer and machine tool industries we find three different patterns of catching ups path creating catching up cdma mobile phone path skipping catching up d ram and automobile and path following catching up consumer electronics personal computers and machine tools we interpret the first two case of catching up as leapfrogging unlike the argument by perez and soete perez c soete l 1988 catching up in technology entry barriers and windows of opportunity in dosi et al eds technical change and economic theory pinter publishers london we find that important r d projects except automobiles where only private r d was involved involved both private and public capacities and that entry was not driven by endogenous generation of knowledge and skills but by collaboration with foreign companies

bank debt restructurings and the composition of exchange offers in financial distress this article examines the relation between bank debt forgiveness and the structure of public debt exchange offers in financial distress i find that the structure of exchange offers and the likelihood of an offer s success are significantly related to whether the bank participates in the restructuring transaction exchange offers made in conjunction with bank concessions are characterized by significantly greater reductions in public debt outstanding and significantly less senior debt offered to bondholders overall the results suggest that the structure of a firm s public and private claims significantly affects the firm s ability to modify its capital structure in financial distress recent empirical studies provide apparently conflicting evidence on the relation between the mix of private and public debt in a firm s capital structure and the ability of the firm to restructure its debt outside of bankruptcy for example gilson john and lang 1990 find that the likelihood of a successful debt restructuring is positively related to a firm s reliance on bank borrowing in contrast asquith gertner and scharfstein 1994 and james 1995 find that for firms with public debt outstanding banks rarely make unilateral concessions indeed the latter two studies suggest that the avoidance of bankruptcy depends on the ability to restructure public not private debt claims finally gilson 1994 finds less debt reduction in financial distress the higher the proportion of bank debt a firm uses in this article i examine the relation between bank debt restructurings and the composition of public debt exchange offers by financially distressed firms the secured status of bank debt and institutional constraints on bank debt for equity swaps imply that banks are unlikely to provide debt forgiveness unless their claims are impaired i e the face value of the bank s claim is greater than the value of the collateral net of transactions and bankruptcy costs 2 however drawing on theoretical work by gertner and scharfstein 1991 i argue that bank participation in a restructuring can play an important role in resolving

repossession and the democratization of credit we exploit a 2004 credit reform in brazil that simplified the sale of repossessed cars used as collateral for auto loans we show that the reform expanded credit to riskier self employed borrowers who purchased newer more expensive cars the legal change has led to larger loans with lower spreads and longer maturities although the credit reform improved riskier borrowers access to credit it also led to increased incidences of delinquency and default our results shed light on the consequences of a credit reform and highlight the crucial role that collateral and repossession play in the liberalization and democratization of credit

the profitability concentration relation market power or efficiency industrial economists have been studying the relationship between profitability and concentration using cross industry samples for many years now however as sometimes happens once it appeared that some consensus had been achieved with few exceptions market concentration and industry profitability are positively correlated peltzman i977 p 229 people began to question the interpretation of those results in particular demsetz e g i973 i974 and others suggested that rather than concentration market power leading to higher prices and profits the causal direction in fact ran from greater efficiency to both higher profits and incidentally to higher concentration our purpose here is to subject these conflicting hypotheses to cross industry empirical test using u k data in order to do this we first develop a model which is sufficiently general to allow for both alternative explanations of a positive concentration profitability correlation in the light of this model we then examine the implications for the within industry relation between market share and firm level profitability more specifically we explore demsetz s claim that the empirical form of this relationship should signal which of the alternative hypotheses is consistent with the between industry profitability concentration correlation our model suggests that in certain special circumstances this claim is partly justified in that it should be possible to assess the relative strengths of the market power and efficiency effects from the within industry relation more generally however factors such as product differentiation and scale economies may seriously impair the information content of the relation with at least a strong suspicion that the estimates will tend to exaggerate the evidence in favour of the efficiency hypothesis in the event our results tend to confirm that for most industries the within industry data offer little conclusive support for either hypothesis but for a not insignificant minority of industries the evidence suggests some support for the view that both efficiency and market power are at work simultaneously our model is detailed in section ii and estimated on u k data in section iii after which we offer a few comments in section iv first however we drovide a backcloth to the later analysis

hedonic valuation of the perceived risks of nuclear power plants we use the 2011 fukushima accident to evaluate the impact of the perceived risks of nuclear power plants on apartment rents in switzerland using online advertisements over 12 years and a difference in differences approach we find a 2 3 price discount after the accident for apartments near nuclear power plants

efficiency and market power in greek food industries this paper uses firm level data to examine the market power versus efficiency hypothesis by taking into consideration both the long run behavior of profitability and the possible endogeneity bias among profitability market share and advertising variables in a sample of 266 greek food manufacturing firms in the period 1987 95 two stage least squares results show both a direct effect of firm characteristics and an indirect effect of industry characteristics on profitability which do not provide support for the efficiency hypothesis alone but they do show that profitability is affected by both firm and industry variables

concentration profitability and trade in a simultaneous equation analysis the case of taiwan this paper is the first attempt to use a simultaneous four equation system to study the role of foreign trade in the analysis of market structure and performance and the determinants of trade intensity in a newly industrializing country taiwan a cross sectional analysis is carried out with the manufacturing censuses of 1976 the results indicate that public enterprises significantly influence market structures and performance also import control measures influence import intensity significantly and offset potential impacts of imports on concentration and on profitability however trade intensity is mainly explained by comparative advantage rather than market forces concentration and profitability

intangible capital aspects of advertising and r d expenditures twenty years have passed since economists first emphasized the intangible capital aspects of advertising according to this view consumers tend to forget brands and continuous advertising is needed to maintain a given rate of sales thus advertising expenditures can be viewed as a capital good that depreciates over time and needs maintenance and repair 22 p 197 more recently weiss 25 among others has suggested that research and development r d costs might also be capitalized as such expenditures yield benefits mainly in the future 25 p 421 unfortunately most analyses of the intangible capital issue have been limited to advertising largely because no comprehensive data on r d were available until quite recently however important recent theoretical contributions on the topic and improvements in data availability now make it possible more completely to consider the intangible capital aspects of both advertising and r d expenditures here the intangible capital issue is investigated through use of a market valuation model in this approach significant future intangible capital effects of advertising and r d are suggested to the extent that current expenditures have significant effects on the market value of the firm given positive market value influences individual coefficient estimates can be used to estimate both the total stock of intangible capital as well as average annual depreciation rates for advertising and r d while these depreciation rate estimates are interfirm averages and undoubtedly err in individual instances they can be quite useful in indicating the general magnitude of corporate profit and tax misstatement due to current reporting and tax policies in section i below various articles closely related to this study are reviewed section ii develops a valuation model embodying intangible capital considerations the data are discussed in section iii and estimation results are presented in section iv and finally conclusions and implications for public policy are discussed in section v

firm and industry effects within strategic management an empirical examination this study brings out the complementarities between resource based and industrial organization schools within strategic management through an empirical examination of firm and industry effects a variance component analysis of 264 single business companies from 69 industries using 5 and 15 year periods suggests that firm effects are more important than industry effects on firm performance but not on core strategies such as technology and marketing the findings also point to the need to study core strategies at lower levels of aggregation to understand the sources of competitive advantage 1998 john wiley sons ltd

testable competing hypotheses from structure performance theory efficient structure versus market power this paper provides a structure performance theory that can accommodate leading firm efficiency as well as several competing market power hypotheses the author derive s testable implications distinguishing the simple collusion product differentiation and scale economy hypotheses from the innovative lea ding firm alternative it is shown that recent evidence of a positive market share price cost margin pcm relationship and a nonpositive concentration pcm relationship can reject the scale economy and simpl e collusion hypotheses in homogeneous product markets unfortunately this same evidence cannot reject the product differentiation hypothe sis in favor of leading firm efficiency copyright 1988 by blackwell publishing ltd

inter industry differences in profitability the legacy of the structure efficiency debate revisited this study presents a simple model on the sources of inter industry variation in profitability and tests its empirical implications in order to shed new light on the long lasting debate over industry profitability the model identifies four key factors that jointly influence an industry s price cost margin i the intensity of strategic investment e g r d and advertising ii the skewness of the distribution of market share or market concentration iii the appropriability of strategic investment and iv the extent to which firms market shares are determined by the intensity of their strategic investment these factors are expected to be positively related to industry profitability and our empirical analysis provides supportive evidence the model also suggests that the conventional single dimensional hypotheses on profitability the market power or market structure hypothesis and the efficiency hypothesis are overly simplified more importantly existing empirical results allegedly supporting each of these hypotheses are spurious to the extent that the distribution of firm specific strategic competence reflects firm heterogeneity in efficiency and at the same time underlies the distribution of market share or market concentration copyright 2009 oxford university press

the risks of nuclear disaster and its impact on housing prices abstract using a data set on housing sales transactions we explore the potential effect of the fukushima disaster on housing prices in sweden in contrast to most earlier findings in other countries we do not find any disproportionate effect from the fukushima disaster on housing prices in vicinity of nuclear power plants in sweden

price and advertising signals of product quality we present a signaling model based on ideas of phillip nelson in which both the introductory price and the level of directly uninformative advertising or other dissipative marketing expenditures are choice variables and may be used as signals for the initially unobservable quality of a newly introduced experience good repeat purchases play a crucial role in our model a second focus of the paper is on illustrating an approach to refining the set of equilibria in signalling games with multiple potential signals

changes in implicit flood risk premiums empirical evidence from the housing market abstract hedonic valuation models have shown that sales prices can capitalize property risk factors such as flood zone properties facing lower risk sell at a premium all else being equal previous research has indicated that price differentials reflecting risk of flooding become much larger in the wake of a storm we re examine these findings for pitt county north carolina using multiple storm events within a difference in differences framework and we compare flood zone price differentials for a more recent sample of property sales prior to hurricane fran in 1996 we detect no market risk premium for the presence in a flood zone but we find significant price differentials after major flooding events amounting to a 5 7 decrease after hurricane fran and 8 8 decrease after hurricane floyd results from a separate model that examines more recent data covering a period without significant storm related flood impacts indicate a significant risk premium ranging between 6 0 and 20 2 for homes sold in the flood zone but this effect is diminishing over time essentially disappearing about 5 or 6 years after hurricane floyd the lack of a persistent effect suggests that buyers and sellers risk perceptions may change with the prevalence of hazard events and that homebuyers are unaware of flood risks and insurance requirements when bidding on properties

market structure and market value while the use of market models to determine the sources of economic profits is quite new at least two empirical studies considering the market structure and market value relation have appeared to date interestingly they conflict thomadakis 1977 found a close positive relation between the four firm concentration ratio and relative excess valuation measured as the difference between the market value of the firm and the book value of tangible assets all normalized by sales as a result thomadakis argued that industry concentration plays a role in the determination of excess profits from currently held assets and those expected from the firm s investment options p 185 in contrast lindenberg and ross 1981 reported no significant relation between concentration and tobin s q ratio measured as the ratio of the market value of the firm to the replacement cost of tangible assets this result disputes thomadakis s findings and a purely structuralist interpretation of economic profits according to lindenberg and ross market power may or may not be evident in highly concentrated markets since high q s can occur in concentrated or unconcentrated markets and conversely low q s indicating no significant market power can occur in markets that have high degrees of concentration p 28

the influence of increased foreign competition on industrial concentration and profitability abstract this paper uses the chilean manufacturing censuses of 1967 and 1979 to examine the effects of the chilean reforms in the mid 1970s on market structure and performance the reforms substantially increased the concentration in industry and substantially reduced profitability these outcomes are interpreted in the light of hypotheses about the effect of potential entrants on market structure and on the pricing behavior of incumbents next a cross sectoral simultaneous equations model of structure and performance is estimated to isolate the contribution of import and export shares to cross sectoral variations in concentration and profitability and to test for structural change between the two censuses the analysis confirms that the liberalization of trade changed the way import and export shares determined profitability and supports the import discipline hypothesis

a new view of the market structure performance debate ion typically considered in market structure performance studies data on cross sections of firms or industries are unlikely to be sufficiently 2 the question of data selection has been discussed fairly thoroughly by weiss 44 and demsetz i 5 among others although there appears to be little agreement on the direction of bias in the most commonly used samples the question of exogeneity has been less thoroughly discussed although in specific instances e g schmalensee 37 martin 27 it has been dealt with explicitly this content downloaded from

may therefore be more productive to return to industry specific analysis there will undoubtedly be some who are unconvinced by this argument and for them we offer the observation that further empirical studies based on weak deductive foundations are likely to be convincing only to the extent that they account explicitly for the role of prior beliefs and specification uncertainty ii determinants of profitability the conventional market structure conduct performance paradigm has guided vast amounts of empirical research in the field of industrial organization for the past three decades like empirical research in other areas of economics the maintained hypotheses that are considered reflect to a large extent the prior beliefs of the researchers the result is that there is always a suspicion that what is being engaged in is more advocacy than objective empirical analysis in the market structure performance literature the most important alternative prior beliefs maintained hypotheses appear to fall into six categories which we characterize as follows i seller concentration explains profits high rates of return are thought to be caused by monopoly power conferred by high degrees of seller concentration this is the basic collusion specification of bain i 2 seller concentration and entry barriers explain profits high rates of return are thought to reflect monopoly power resulting from both high seller concentration and high barriers to entry this prior comes from the traditional market structure performance paradigm of industrial organization and accounts for the peristence of collusive gains it is prevalent in the work of mann 26 weiss 45 46 comanor and wilson i i qualls 34 1j35 and many other researchers 3 absolute or relative firm size explain profits this prior reflects the demsetz i4 i5 and peltzman 133 notion that high rates of return result from superior firm efficiency or innovativeness and not from oligopolistic collusion and joint profit maximization this prior has also been adopted by others e g shepherd 39 gale i7 who assume that high market shares indicate high barriers to entry 4 risk differentials explain profitability differences this reflects the notion that high rates of return reflect neither monopoly power nor superior efficiency but the payment of positive risk premiums to risk averse investors it underlies much of the work of stigler 4i fisher and hall i6 cootner and holland i3 and many others there are however considerable differences in beliefs about which measure of risk variability of

market structure performance debate 40i 5 advertising intensity explains profits this reflects the notion of bloch 4 and others that differences in reported accounting profit rates result from

hypothesis that profitability differences result not from monopoly power but from adjustments in capacity lagging behind changes in demand given a particular maintained hypothesis about the most important determinant of profitability there remains uncertainty about the rest of the specification of the model if the results are not robust with respect to uncertainty about the conditioning set of variables then it cannot be concluded that the data are very informative about the hypothesis in question the next section discusses the methodology used to determine whether the results are robust to such specification uncertainty iii specification uncertainty the hypotheses discussed in the previous section all specify the primary determinants of profitability in each case however the investigator must have in mind a set of possible conditioning variables that may or may not belong in the regression although uncertainty about the inclusion or exclusion of such variables is not often explicitly acknowledged it is an inevitable and important aspect of virtually all empirical investigations the primary concern for the problem at hand is the extent to which this specification uncertainty leads to uncertainty in the estimated parameters of primary interest consider the regression model

do markets differ much this essay reports the results of a crosssection study of differences in accounting profitability that sheds light on some basic controversies in industrial economics most previous cross section studies in this field have been concerned with testing hypotheses about structural coefficients in models meant to apply to essentially all markets as we have learned more about the difficulties of constructing such general models and of performing tests on their structural parameters properly structural cross section analysis has fallen out of fashion in contrast to most of the cross section literature the analysis reported here is fundamentally descriptive it does not attempt directly to estimate or to test hypotheses about structural parameters i hope to show by example that one can perform illuminating analysis of cross section data without a host of controversial maintained hypotheses cross section data can yield interesting stylized facts to guide both general theorizing and empirical analysis of specific industries even if they cannot easily support full blown structural estimation one can view the sort of search for stylized facts conducted here as either a replacement for or an input to interindustry structural estimation depending on one s feeling about the long run potential of that research approach this study also departs from much of the cross section literature by being fundamentally concerned with the importance of various effects not just with coefficient signs and t statistics in particular this essay provides estimates of the relative importance of firm market and market share differences in the determination of business unit divisional profitability in u s manufacturing using 1975 data from the line of business program of the u s federal trade commission ftc i find support neither for the existence of firm effects nor for the importance of market share effects moreover while industry effects apparently exist and are important they appear to be negatively correlated with seller concentration in these data section i relates firm market and share effects to current issues and controversies in industrial economics and thus supplies the motivation for our empirical analysis the remainder of the essay treats the data and

collusion versus differential efficiency testing alternative hypotheses the predictions of collusion and efficiency based static equilibrium explanations of interindustry profitability differences are formally developed and tested using appropriate econometric techniques with intraindustry data on seventy u s internal revenue service minor manufacturing industries in 1963 and 1972 none of the explanations has much explanatory power the 1963 data are consistent with collusion based models while the 1972 data are inconsistent with all non null hypotheses considered patterns of profitability are sharply different in the two years in complex ways apparently unrelated to cyclical forces or the phase ii price controls implications of these results are discussed copyright 1987 by blackwell publishing ltd

bankruptcy law and bank financing exploiting the timing of the 2005 2006 italian bankruptcy law reforms we disentangle the effects of reorganization and liquidation in bankruptcy on bank financing and firm investment a 2005 reform introduces reorganization procedures facilitating loan renegotiation the 2006 reform subsequently strengthens creditor rights in liquidation the first reform increases interest rates and reduces investment the second reform reduces interest rates and spurs investment our results highlight the importance of identifying the distinct effects of liquidation and reorganization as these procedures differently address the tension in bankruptcy law between the continuation of viable businesses and the preservation of repayment incentives

beyond firm and industry effects on profitability in imperfect markets the federal trade commission s line of business data imply that the effect of an industry s seller concentration on profitability has been misinterpreted because it has not been conditioned on capital intensity conclusions that market share rather than seller concentration is the primary structural determinant of profitability and that mutual dependence recognized among oligopolistic sellers is less important than superiority effects of large share firms appear unwarranted significant firm effects exist and explanatory power for a conventional model of structure and performance is found to be small relative to that of the general linear model within which the conventional model is nested
