socio economic characteristics and the effect of taxation as a health policy instrument abstract this paper analyses the quantitative effects of using economic instruments in health policy on the basis of price elasticities calculated from estimated demand systems the nutritional effects of various taxation schemes are compared for households in different age groups and social classes focusing on the consumption of saturated fats fibre and sugar it is generally found that the impact of price instruments is stronger for lower social classes than in other groups of the population with regard to age groups it is mostly the youngest that decrease their demand for saturated fat in response to price changes while it is mostly the middle aged who exhibit price responsiveness in their demand for sugar these groups are however not considered as key target groups for dietary regulation thus tax instruments may be effective in improving diets on average but the design of the instruments and the targeting of vulnerable groups with special needs should be done with care it should be noted that a tax on a single nutrient or food may have undesired effects on the demand for other food components though this may be avoided by introducing taxes subsidies on several food products simultaneously

how firms respond to financial restatement ceo successors and external reactions although past studies have paid considerable attention to firms reputations few have investigated the actions that firms take following a reputation damaging event we identify firms involved in financial earnings restatements and examine whether naming a successor ceo with specific qualities serves to signal the seriousness of a firm s efforts to restore its reputation using theories of market signaling we argue that attributes of successor ceos significantly influence the reactions of key external constituencies in particular firms with more severe restatement tend to name successors who have prior ceo or turnaround experience and a more elite education the naming of such successors results in more positive reactions from the stock market financial analysts and mass media we argue that these attributes send messages to stakeholders and the broader public about the ceo s credibility and the firm s efforts

indirect currency substitution a structural approach abstract previous empirical tests of mckinnon s indirect currency substitution ics hypothesis based on macro reduced form models yield ambiguous results because evidence cannot discriminate ics from competing non monetary models this note suggests a structural model based on the money demand function preliminary evidence supports mckinnon s hypothesis for the federal republic of germany switzerland canada and the netherlands but not for the u s

who appropriates centrality rents the role of institutions in regulating social networks in the global islamic finance industry this study explains and tests the effects of country level institutions on the distribution of centrality rents between two sets of actors in an interorganizational network building on the literature on corporate elites we propose that a cohesive elite following organizational logics other than profit maximization diverts centrality rents and induces costs on firms and that macro institutions act as external governance mechanisms to shape this relationship we develop our theory in the emerging islamic finance industry where shariah scholars connect firms and constitute a religious corporate elite while central scholars in this network create legitimacy for firms they also shirk and cause information leakage suggesting a negative centrality performance relationship for the firms country level institutions such as government regulation and democracy we argue ameliorate these effects by influencing this religious elite s institutional logic and restraining their actions while institutions developed from within the industry strengthen the power of the elite testing our theory in a network of 367 scholars and 396 institutions over 31 countries using multi level methods we indeed find a negative centrality performance relationship that is ameliorated by stronger government regulation but exacerbated by better developed industry specific institutions as well as a negative relationship between democratic and regulatory institutions and centrality

currency preferences and the australian dollar abstract we investigate currency substitution and currency complementarity in the case of the australian dollar data spanning 1984 2003 contain evidence of the australian dollar s substitution for the deutschmark and complementarity with the yen and the us dollar consistent with the theory that international variables will in general affect the demand for domestic money atemporally nonseparable preferences also give rise to the possibility of third currency effects our regressions find some evidence of these for example a rise in the us federal funds rate has been associated with rises in the value of the australian dollar against the mark and yen controlling for changes in other interest rates and in money supplies and real outputs

quasi and simulated likelihood approaches to censored demand systems food consumption by food stamp recipients in the united states a quasi maximum likelihood estimator is proposed and applied to a censored translog demand system for foods using a sample of food stamp recipients in the united states the procedure produces remarkably close parameter and elasticity estimates to those of the simulated maximum likelihood procedure a two step procedure is also considered but it produces different elasticities demands are found to be price elastic for pork and fish but price inelastic for all other food products gross complementarity and net substitutability are obvious but these cross price effects are much less pronounced than own price and total food expenditure effects copyright 2003 oxford university press

inflation and welfare in a monetary economy it is in everyone s private interest to try to get someone else to hold non interest bearing cash and reserves but someone has to hold it all so these efforts must simply cancel out all of us spend several hours per year in this effort and employ thousands of talented and highly trained people to help us these person hours are simply thrown away wasted on a task that should not have to be performed at all

getting off to a good start the effects of upper echelon affiliations on underwriter prestige the initial public offering ipo is one of the most critical events in the lifetime of a young firm prior research has shown that firms tend to have successful ipos if they go public with the endorsement of a prestigious lead underwriter this paper examines the antecedents to receiving endorsement by a prestigious underwriter and links this to the experience base of a firm s upper echelon we theorize that the amount and type of upper echelon experience serve as important symbols of a young firm s legitimacy to critical outsiders we introduce a typology of upper echelon experience that distinguishes between upper echelon upstream horizontal and downstream employment based affiliations and suggest that these different types of upper echelon affiliations allay different types of endorser concerns regarding firm legitimacy affecting the endorsement process further we theorize that the relationships between upper echelon experience and investment bank prestige will be moderated by technological uncertainty we test our assertions on a comprehensive sample of public and private biotechnology firms that were founded between 1961 and 1994 and that went public between 1979 and 1996 analyses of the five year career histories of the over 3 200 executives and directors that make up the upper echelons of these firms show that firms with upper echelons with affiliations with prominent downstream organizations i e pharmaceutical and or healthcare companies and with prominent horizontal organizations i e biotechnology companies are more likely to attract the endorsement of a prestigious investment bank we also find that the greater the range of upper echelon affiliations across the categories of upstream horizontal and downstream affiliations the more prestigious the firm s lead underwriter we also find that these latter results are moderated by technological uncertainty the present research has implications for the study of organizational legitimacy interorganizational endorsements and entrepreneurship

quality quantity and spatial variation of price this paper develops and implements a method for estimating price elasticities of demand using cross sectional household survey data geographically clustered households report unit values which when corrected for quality effects and for measurement error indicate the underlying spatial variation in prices and can be matched to variation in demand patterns a simple model of quality choice is proposed while the correction for measurement error exploits the clustered design of such surveys data from a 1979 household survey from the ivory coast are used to estimate price elasticities for beef meat fish cereals and starches copyright 1988 by american economic association

demand systems estimation with microdata a censored regression approach demand systems estimation increasingly makes use of household level microdata mainly to measure the effects of demographic variables data based on these household expenditure surveys present a major estimation problem for any given household many of the goods have zero consumption implying a censored dependent variable techniques which do not take this censored dependent variable into account will yield biased results we utilize a censored regression approach that is computationally simple consistent and asymptotically efficient the results are then presented and compared with those obtained using an uncensored technique

the conditional nature of embeddedness a study of borrowing by large u s firms 1973 1994 economic and organizational sociologists have increasingly demonstrated that the actions of individuals and firms are affected by the social networks within which they are embedded in recent years scholars have begun to recognize that the effects of these social networks may vary across populations or types of relations this article examines the extent to which the effects of interfirm networks on the behavior of firms are historically contingent focusing on the level of debt financing among approximately 140 large u s corporations over a 22 year period the authors show that the extent to which the firms use of debt was influenced by those with which they were tied through director interlocks declined over time the authors argue that this decline in the network effect reflected a shift in the institutional environment within which the firms operated and that it was driven by three processes the professionalization of the finance function within the firm the internalization of financial decision

predicting the effects of sugar sweetened beverage taxes on food and beverage demand in a large demand system a censored exact affine stone index incomplete demand system is estimated for 23 packaged foods and beverages and a numeraire good instrumental variables are used to control for endogenous prices a half cent per ounce increase in sugar sweetened beverage prices is predicted to reduce total calories from the 23 foods and beverages but increase sodium and fat intakes as a result of product substitution the predicted decline in calories is larger for low income households than for high income households although welfare loss is also higher for low income households neglecting price endogeneity or estimating a conditional demand model significantly overestimates the calorie reduction

did the junk food tax make the hungarians eat healthier i analyse whether the introduction of the unhealthy food tax lead to significant improvements in the dietary habits of the hungarian population i focus on the consumption of processed and unprocessed food before and after the tax was levied on a range of food high in salt and sugar using data from a large scale household panel data set i estimate the consumed quantities of processed food to decrease by 3 4 due to the unhealthy food tax while the consumed quantities of unprocessed food increased by 1 1 the lowest income groups were the most responsive to the introduction of the tax despite data limitations the results indicate moderate improvement in population diet that is likely to be attributable to the tax

domestic alliance network to attract foreign partners evidence from international joint ventures in china partner selection is a critical issue in building international joint ventures ijvs we argue that foreign firms are more likely to select local firms with unique network structural advantages within a local alliance network we frame structural advantages as two network position traits centrality and brokerage specifically network centrality acts as a stronger network trait than brokerage in attracting foreign ijv partners however such a relationship may be moderated by foreign firms local experience and perceived capabilities we contend that when foreign firms have a high level of local market experience and perceived capabilities they may prefer a local broker over a centrally located local firm data on the domestic alliance network in china s electronics and information technology it industries largely support our hypotheses we conclude that as foreign investors become strategic insiders they may not only seek a local partner s capability attributes but also more critically pay attention to a local partner s domestic network

currency substitution and the demand for money some evidence for canada recently the possibility that foreign and domestic currencies are substitutes has received considerable attention see 1 2 3 10 19 21 currency substitution has important implications for the working of flexible exchange rates if the degree of currency substitution is high small changes in the money supply would induce large changes in the exchange rate furthermore currency substitution would transmit the effect of monetary disturbances from one country to another indeed significant currency substitution would seriously undermine the ability of flexible exchange rates to provide monetary independence this paper examines the empirical importance of currency substitution in the framework of the demand function for money if currency substitution is important the expected change in the exchange rate should be a significant determinant of the demand for home currency in section 2 we undertake such a test for the canadian demand for money during the recent flexible exchange rate period there is considerable evidence that the forward exchange rate is a good measure of the expected exchange rate our own tests confirm these results for canadian data since 1970

habit formation and demand for sugar sweetened beverages using scanner data we estimated demand for nine nonalcoholic beverages under habit formation we found strong evidence for habit formation although demand for sugar sweetened beverages by low income households is less elastic to own price changes compared with high income households there is evidence that high income households consider beverages to be more substitutable than low income households do a half cent per ounce tax on store purchased sugar sweetened beverages will result in a moderate reduction in consumption of sugar sweetened beverages for both income strata because of habit formation long run national tax revenue from a sugar sweetened beverage tax is about 15 to 20 lower than short run revenue

cross currency cross maturity forward exchange premiums as predictors of spot rate changes theory and evidence abstract this paper shows that in predicting the spot rate of a currency the term structures of forward premiums of other currencies have incremental information content in addition to the term structure of the currency s own forward premiums the theoretical model motivating the analysis hinges on the abundant evidence on the co movements of excess returns from investing in different currencies the empirical results are obtained through fiml estimation of a vector error correction model for weekly data on three bilateral us dollar exchange rates

networks as the pipes and prisms of the market1 this article draws an analytical distinction between two types of market uncertainty egocentric which refers to a focal actor s uncertainty regarding the best way to convert a set of inputs to an output desired by a potential exchange partner and altercentric which denotes the uncertainty confronted by a focal actor s exchange partners regarding the quality of the output that the focal actor brings to the market given this distinction the article considers how the value of structural holes and market status vary with these two types of uncertainty the article proposes that the value of structural holes increases with egocentric uncertainty but not with altercentric uncertainty in contrast the value of status increases with altercentric uncertainty but declines with egocentric uncertainty thus actors with networks rich in structural holes should sort into markets or market segments that are high in egocentric uncertainty high status actors should sort into markets that are low in egocentric

relative price changes as a tool to stimulate more healthy food choices a danish household panel study abstract the increased prevalence of lifestyle related illnesses particularly in western countries calls for public action a poor diet is a key explanatory factor to this development previous research has addressed the problem of unhealthy food consumption behavior by looking at how taxes may function as an instrument to change purchase behavior from less healthy products to healthier ones in this paper we address this issue by looking at the effects of discounts depending on whether healthy or less healthy products are available at a discount our study is based on weekly purchase data from a danish household panel for the period 2010 2011 interestingly from a public health perspective our findings suggest that there is an asymmetric effect of discounts depending on the fat content of the product furthermore our results point at two classes of consumers where the asymmetric effects go in different directions

getting known by the company you keep publicizing the qualifications and former associations of skilled employees when product quality cannot be ascertained in advance of purchase producers must convince relevant audiences that they are worthy of consideration as quality players we propose that quality oriented producers will selectively publicize information about their skilled employees in anticipation of signaling benefits which include the accrual of visibility and the projection of quality based identities we validate our perspective on publicizing affiliation information by analyzing how a sample of australian wine producers publicized specific career information about their skilled employees i e their winemakers including the names of certain former employers of these individuals copyright 2009 oxford university press

the effects of a fat tax on french households purchases a nutritional approach this article assesses the effects of a fat tax on the nutrients purchased by french households across different income groups this is done by making a preliminary estimation of price elasticities using a complete demand system on household scanner data and by calculating nutrient elasticities using estimated price elasticities we find that a fat tax has small and ambiguous effects on nutrients purchased by french households and a slight effect on body weight in the short run with a greater effect in the long run such a tax generates substantial tax revenue but is highly regressive

toward an aspiration level theory of open innovation although open innovation has become increasingly established in the management literature comprehensive theoretical explanations of what drives firms to be open are sparse taking the perspective of the behavioral theory of the firm we conceive of open innovation as a form of nonlocal search arguing that firms will turn to open innovation when substantially under or over performing relative to their aspirations we further enquire how this relationship is moderated by firm specific innovation related resources human capital research and development investment and patents employing a representative survey of uk firms we find some evidence of moderation allowing us to present explanations of search through open innovation and contribute to the behavioral theory of the firm itself

between preferences and references asymmetric price elasticities and the simulation of fiscal policies abstract canonical demand studies and fiscal policy simulations rest on the assumption that consumers react symmetrically to price increases and decreases such assumption has been challenged from both the empirical and theoretical points of view we propose theoretically consistent empirical specifications to estimate discrete choice models random utility dcm and continuous demand systems easi and aids demand systems that allow for reference prices and asymmetric own and cross price demand response our application focuses on the demand for sugar sweetened beverages in great britain using transaction level household purchase data and different product aggregation levels we find substantial evidence of asymmetric consumer response and loss aversion with a stronger response when prices rise above their reference level our results hold for both dcms on highly differentiated products and demand systems on aggregate product categories and are robust to alternative model and reference price specifications simulations of taxes and subsidies on soft drinks shows that ignoring asymmetry may lead to biases especially when predicting price cuts

quality quantity and spatial variation of price back to the bog abstract estimating potential effects of price reforms is a key issue for many developing countries demand studies increasingly use household survey data on budget shares which vary with quantity price and quality if quality response to price is ignored estimated price elasticities of quantity demand conflate responses on quantity and quality margins our review finds over 80 of published studies using budget shares from household survey data have this error we use survey data from vietnam with prices and qualities observed over space to directly estimate the price elasticity of quality this is much larger than what is derived from the income elasticity of quality based on the deaton 1988 separability restrictions across the 45 items we study the own price elasticity of quantity demand is overstated by a factor of four on average if the response of quality to price is ignored

charting the territory recombination as a source of uncertainty for potential entrants in this paper we conceptualize categories as regions of a cognitive map that structure the market and guide the investment decisions of potential entrants i e of new and established organizations we advance that as a category appears altered via incumbents acts of recombination potential entrants face market specific uncertainty and are discouraged to invest in that category these negative effects of recombination on market entries are however mitigated at increasing values of category status we test our arguments in the market for electronic music the analyses of product and organizational entries in music styles between 1978 and 2011 lend support to our arguments

the dynamics of organizational status this paper examines the growth and decline of organizational status it is argued that an organization s status is determined by two factors past performance outcomes and the status of the organization s affiliates the better the past performance outcomes and the higher the status of the affiliates the greater the organization s growth in status this basic proposition is tested in an examination of status changes among investment banks in the non investment grade market between 1981 and 1987 implications and extensions are discussed in the conclusion copyright 1996 by oxford university press

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

the welfare effects of health based food tax policy this paper examines the effects of health oriented food tax reforms on the distribution of tax payments food demand and health outcomes we offer an illustration of how one can take into account the uncertainty related to both demand estimation and health estimates and to produce confidence intervals for the overall health effects instead of only point estimates taxation of sugar could lead to a statistically significant reduction in both the incidence of type 2 diabetes and coronary heart disease the health effects appear to be most pronounced for low income individuals and the reforms may therefore reduce health inequality this effect undermines the traditional regressivity argument against the heavy taxation of unhealthy food

dynamic information spillovers in intraregionally focused spot and forward currency markets abstract this paper proposes an intraregionally focused tri currency modeling framework to investigate dynamic information spillovers across spot and forward exchange rate markets in frontier and emerging country currencies for both price levels and volatilities empirical estimates of structural parameters were obtained using an mgarch mskst model that incorporated the term structure of non deliverable forward ndf and deliverable forward df markets the dominance of regional currencies and the influence of differing forward contract maturities 1 3 6 and 12 months the currencies for nine countries were grouped into three regions northeast asia china korea and taiwan south southeast asia india indonesia and philippines and latin america brazil chile and columbia the currency for each selected country was evaluated within the regionally determined tri currency system we found that ndf markets play a dominant role over df markets with regard to price discovery during periods of tranquility during periods of crisis both ndf and df markets exhibit a more balanced impact on currency market price discovery mechanisms in addition distinct differences were observed across regions currencies in northeast asia were shown to be affected by the chinese renminbi during periods of crisis and the indian rupee could be regarded as the dominant currency in south southeast asia no robust results were obtained with regard to the dominance of currencies in latin america finally our results also suggest important distinctions between the effect of various instrument maturities on ndf and df market returns with df returns being more responsive to longer maturities 6 months and 12 months during tranquil periods ndf returns are more responsive to shorter maturities but during crisis periods this effect is diminished

momentary exchange rate locked in a triangular mechanism of international currency this study uses two way quoted data on major and nonmajor currencies to test the exchange rate dynamics particular attention is paid to the arbitrage and the spread in triangular foreign exchange trades there is only one possible triangle when a bilateral exchange rate equals its trilateral rate otherwise any third currency would potentially create arbitrage opportunities empirical testing evidence supports that small but possibly exploitable profitable arbitrage has significantly occurred over the very short haul of uncertainty and turbulence in other words we are convinced that the bilateral exchange rate could be diverged from one common currency side of the trilateral basket rates until markets function efficiently this helps in better explaining foreign exchange rate movements in addition we find that the currency correlating decreases slightly but the volatility increases over time as we expected

the liability of good reputation a study of product recalls in the u s automobile industry in this paper we explore opposing theoretical claims about how organizational reputation affects market reactions to product defects on the one hand good reputation could be a disadvantage because expectations about product quality are more likely to be violated by defects in highly reputed products on the other hand a good reputation could be an advantage because of strong inertial effects on reputation orderings we empirically test these competing hypotheses using data on product recalls in the u s automobile industry from 1975 to 1999 our results support for the idea that reputation can be an organizational liability in that highly reputed firms suffer more market penalty as a result of their product recalls we also propose that the reputational effects are moderated by two important factors substitutability and generalism specialism our results show that having few substitutes with an equivalent level of reputation or a focused product identity stemming from specialism buffers the negative market reactions to product recalls we conclude with a discussion on the implications of these results for institutional reputation and status theories

characteristics of firms correcting previously reported quarterly earnings abstract this paper analyzes economic characteristics of firms that correct previously reported quarterly earnings the basic findings are that relative to their industry the sample correcting firms are smaller less profitable have higher debt are slower growing and face more serious uncertainties their average stock returns between the issuance of erroneous quarterly reports and their correction are negative also correction disclosure frequently precedes sec or stockholder suits against firm management results are consistent with predictions based on the economic interests of management and their auditors

network composition collaborative ties and upgrading in emerging market firms lessons from the argentine autoparts sector what types of relational and institutional mechanisms shape knowledge flows and the upgrading capabilities of emerging market firms in the face of economic liberalization we analyze the argentine autoparts sector to distinguish the relative impact of different types of network relationships on a firm s process and product upgrading a few social ties to international assemblers appear to be most beneficial for local suppliers although they may be insufficient to compensate fully for the negative effect of being located in a lower tier supplier customer relationships that are part of regular disciplined discussions for product and process improvements appear to be especially beneficial for upgrading

the decline of social entrenchment social network cohesion and board responsiveness to shareholder activism shareholder activism through corporate governance proposals is a prominent avenue for investors to voice their concerns in corporate governance matters however shareholder proposals have an uneven effect on corporate governance this paper contributes to research on shareholder activism by joining social movement approaches to activism with network theoretic approaches to corporate governance the paper examines how firms position within cohesive sections of the board interlock network termed social entrenchment predicts 1 the likelihood of being targeted by activist investors and 2 firms responsiveness to proposal demands first a firm s position in the board network serves as a salient network prism attracting activists attention this is especially true for activist investors who lack other backchannel avenues for engagement or seek to use public reputational penalties as part of their activism strategy second the board network traditionally served as an important collective infrastruc

the effect of prices on nutrition comparing the impact of product and nutrient specific taxes this paper provides an analysis of the role of prices in determining food purchases and nutrition using very detailed transaction level observations for a large nationally representative sample of us consumers over the period 2002 2007 using product specific nutritional information we develop a new method of partitioning the product space into relevant nutritional clusters that define a set of nutritionally bundled goods which parsimoniously characterize consumer choice sets we then estimate a large utility derived demand system over this joint product nutrient space that allows us to calculate price and expenditure elasticities using our structural demand estimates we simulate the role of product taxes on soda sugar sweetened beverages packaged meals and snacks and nutrient taxes on fat salt and sugar we find that a 20 nutrient tax has a significantly larger impact on nutrition than an equivalent product tax due to the fact that these are broader based taxes however the costs of these taxes in terms of consumer utility are only about 70 cents per household per day a sugar tax in particular is a powerful tool to induce healthier nutritive bundles among consumers

the effectiveness of taxes in decreasing candy purchases abstract we use candy purchase data at the household level to analyze changes in candy purchases due to colorado s candy tax colorado is one of the many states that exempts candy containing flour from their candy tax to do this we construct a dataset of monthly household taxed and tax exempt candy purchases for the years 2009 and 2010 for the denver co and omaha ne metros difference in differences estimates imply that colorado s candy tax led to a decrease in taxed candy purchases of at least 11 2 which would translate into a reduction of household body weight of at least one pound during the first year the tax is in effect conversely we find no effect on the purchase of tax exempt candy

designing a tax to discourage unhealthy food and beverage purchases the case of chile the global shift towards diets high in sugar sweetened beverages ssbs and energy dense ultra processed foods is linked to higher prevalence of obesity diabetes and most other noncommunicable diseases ncds causing significant health costs chile has the highest ssb consumption in the world very high junk food intake and very rapid increases in these poor components of the diet plus obesity prevalence this study s purpose is to compare the effect of different tax schemes for ssbs and ultra processed foods on nutrient availability utilizing price elasticities which are estimated from a quadratic almost ideal demand system model using the 2011 2012 income and expenditure survey we take into account the high proportion of households not purchasing various food and beverage groups censored nature of data the food groups considered were sweets and desserts salty snacks and chips meat products and fats fruits vegetables and seafood cereals and cereal products ssb ready to drink ssb from concentrate plain water coffee and tea and milk which together represent 90 of food expenditures the simulated taxes were 1 40 price tax on ssbs 22 above the current tax level 2 a 5 cents per gram of sugar tax on products with added sugar and 3 30 price tax on all foods 27 above current tax levels and beverages 12 above the current tax level exceeding thresholds on sodium saturated fat and added sugar and for which marketing is restricted based on a chilean law effective june 16 2016 unhealthy foods are price elastic 1 99 for salty snacks and chips 1 06 for ssbs ready to drink and 1 27 for ssbs from concentrate meaning that the change in consumption is proportionally larger with respect to a change in price results are robust to different model specification and consistent among different socioeconomic sub populations overall the tax on marketing controlled foods and beverages is associated with the largest reduction in household purchases of sodium added sugar saturated fat and calorie purchases chile is unique in currently having instituted a small current ssb tax as well as marketing controls and front of package labeling of unhealthy foods and beverages the design of a larger more comprehensive tax to enhance the overall effect of these policies on healthier diets is a next critical step this study shows that a large tax on the same foods and beverages already delineated as unhealthy by the marketing controls and front of pack labeling should prove to be more effective for promoting a healthier diet

the curvilinear relationships between structural embeddedness and productive efficiency an exploratory study abstract existing network studies pay much attention to the benefits of structural embeddedness however uzzi 1996 points out the marginal benefits of structural embeddedness may follow a pattern of diminishing returns using major customer disclosure data from compustat this study investigates the curvilinear relationships between multiple aspects of structural embeddedness and productive efficiency applying both wang and ho 2010 and chen and lin 2009 stochastic frontier models we confirm the diminishing returns of eigenvector and betweenness centralities with a partial support for interconnectedness implications from our findings can help decision makers better understand the effects of structural embeddedness and help devise network structural change strategies for productive efficiency

tax incidence with strategic firms in the soft drink market abstract because soft drink sd consumption is considered to be a contributor to the epidemic of obesity there is a growing interest in evaluating the impact on sd consumption of alternative tax policies in this paper we propose a methodology to evaluate the impact of taxation of a food market taking into account the strategic price response of both manufacturers and retailers we apply this methodology to the french sd market and simulate the impacts of ad valorem and excise taxes we find that firms behave differently when facing an ad valorem tax or an excise tax an excise tax is overshifted to consumer prices while an ad valorem tax is undershifted to consumer prices we find that an excise tax based on the sugar content of sd is the most effective at reducing sd consumption our results also indicate that ignoring strategic pricing by firms leads to misestimations of the impact of taxation by between 15 and 40 depending on the products and the tax implemented in the short term that is ignoring positive long term health effects a 9 cents l excise tax has a small negative welfare effect about 1 person year

r d subsidies external collaborative breadth differential gains and the role of collaboration experience abstract external collaboration breadth is important for firms to acquire the knowledge needed to innovate in this paper we combine cross sectional and longitudinal data from the spanish panel of technological innovation survey pitec to examine the indirect impact of r d subsidies on firm external collaboration breadth we contribute to understanding of the indirect impacts of r d subsidies by first providing strong evidence of an economically significant average positive impact of r d subsidies on firm external collaboration breadth second our results advance understanding of the differential impacts of r d subsidies by revealing the vast heterogeneity of the impact at the firm level where approximately only half of treated firms experience a positive collaboration impact from r d subsidies while the remainder experience no impact or a negative effect finally we advance understanding of the characteristics explaining the differential impact of r d subsidies on external collaboration breadth by utilising the organisational learning literature to demonstrate the important role of firm collaboration experience

the effects of taxes on purchases of sugar sweetened carbonated soft drinks a quantile regression approach the consumption of large quantities of sugar sweetened carbonated soft drinks sscsd may lead to obesity which is associated with health problems such as diabetes cardiac diseases and mental health problems the effects of increasing the value added tax vat on purchases of sscsd are estimated obesity is more likely among heavy drinkers than among light or moderate drinkers therefore the effects on high and low purchasing households are estimated by using quantile regressions qrs on norwegian household purchase data since many households did not purchase sscsd during each survey period censored as well as ordinary qrs are used our results suggest that a vat increase from 13 to 25 will have the highest percentage effect among low purchasing households but the absolute effect is highest among high purchasing households low purchasing households will reduce their purchases by about 5 l while the reduction is almost 20 l among high purchasing households however the effects among high purchasi

management turnover and governance changes following the revelation of fraud abstract fraud scandals can create incentives to change managers in an attempt to improve the firm s performance recover lost reputational capital or limit the firm s exposure to liabilities that arise from the fraud it also is possible that the revelation of fraud creates incentives to change the composition of the firm s board to improve the external monitoring of managers or to rent new directors valuable reputational or political capital despite such claims we find little systematic evidence that firms suspected or charged with fraud have unusually high turnover among senior managers or directors in univariate comparisons there is some evidence that firms committing fraud have higher managerial and director turnover but in multivariate tests that control for other firm attributes such evidence disappears these findings indicate that the revelation of fraud does not in general increase the net benefits to changing managers or the firm s leadership structure

venture capitalists and cooperative start up commercialization strategy this paper examines the possible impact of venture capital vc backing on the commercialization direction of technology based start ups by asking to what extent if at all do vc funded start ups engage in cooperative commercialization strategies strategic alliances or technology licensing or both relative to a comparable set of start ups and with what consequences to address these questions i assemble a novel data set that matches firms receiving a federal research and development subsidy through the u s small business innovative research program to vc funded firms by observable characteristics in five technology intensive industries these data allow decoupling of cooperative activity resulting from start up development via the passage of calendar time from that due to association with vcs an analysis of the 696 start ups in the sample split by an external funding source suggests substantial boosts in both cooperative activity associated with vc backed firms and in the likelihood of an initial public offering

quadratic engel curves and consumer demand this paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative prices a nonparametric analysis of consumer expenditure patterns suggests that engel curves require quadratic terms in the logarithm of expenditure while popular models of demand such as the translog or the almost ideal demand systems do allow flexible price responses within a theoretically coherent structure they have expenditure share engel curves that are linear in the logarithm of total expenditure we derive the complete class of integrable quadratic logarithmic expenditure share systems a specification from this class is estimated on a large pooled data set of u k households models that fail to account for engel curvature are found ro generate important distortions in the patterns of welfare losses associated with a tax increase

the impacts of inclusive and exclusive taxes on healthy eating an experimental study abstract based on a laboratory experiment conducted with 131 adults non students subjects we empirically examine the differential impacts of an inclusive and exclusive tax on changing consumers eating behavior we compare the caloric and nutrient content of the meals selected by the subjects using a difference in difference regression model to determine the efficacy of the policy treatments the results indicate that an inclusive tax has a significantly stronger effect on reducing the consumption of total calories calories from fat and the intake of carbohydrates cholesterol sugar and sodium compared with an exclusive tax
