asset pricing with loss aversion using standard preferences for asset pricing has not been very successful to match asset price characteristics such as the risk free interest rate equity premium and the sharpe ratio to time series data behavioral nance has recently proposed more realistic preferences such as preferences with loss aversion to model asset pricing research has now started to explore the implications of behaviorally founded preferences for asset price characteristics encouraged by some studies of benartzki and thaler 1995 and barberis et al 2001 we study asset pricing with loss aversion in a production economy we here employ a stochastic growth model and use a stochastic version of a dynamic programming method with adaptive grid scheme to compute the above mentioned asset price characteristics of a model with loss aversion in preferences as our results show a model with loss aversion performs considerably better than pure consumption based asset pricing models

modeling the virtuous circle of innovation a test on italian firms this article investigates the virtuous circle between innovative inputs outputs and economic performance with a three equation model highlighting feedback loops and simultaneous relations an empirical test is conducted of innovative expenditure innovative sales and economic results in a sample of italian manufacturing firms comparing occasional and serial innovators the data for 1998 2007 are drawn from a rich panel of italian firms with 20 or more employees compiled by the italian national institute of statistics including three waves of community innovation surveys the model extends that developed at the industry level by bogliacino and pianta industrial and corporate change 2013a 22 3 649 678 innovation and demand in industry dynamics r d new products and profits in a pyka and e s andersen eds long term economic development economic complexity and evolution springer verlag berlin 2013b and confirms those earlier findings for the core of persistent innovators there are complex links at play in different phases of the innovation process and in the feedback between economic success and sustained innovation expenditure

do pharmacists buy bayer informed shoppers and the brand premium we estimate the effect of information and expertise on consumers willingness to pay for national brands in physically homogeneous product categories in a detailed case study of headache remedies we find that more informed or expert consumers are less likely to pay extra to buy national brands with pharmacists choosing them over store brands only 9 percent of the time compared to 26 percent of the time for the average consumer in a similar case study of pantry staples such as salt and sugar we show that chefs devote 12 percentage points less of their purchases to national brands than demographically similar nonchefs we extend our analysis to cover 50 retail health categories and 241 food and drink categories the results suggest that misinformation and related consumer mistakes explain a sizable share of the brand premium for health products and a much smaller share for most food and drink products we tie our estimates together using a stylized model of demand and pricing

causal relationships between public sector agricultural research expenditures and output allocative decisions concerning public sector agricultural research appear to be driven by both supply and politically mediated demand forces in sample granger tests along with post sample predictive tests suggest that simultaneity issues should not be ignored when modeling the research expenditure output relationship the results also provide strong evidence that the impact of research expenditures on agricultural output may persist for as long as thirty years these lags are substantially longer than those commonly used for agricultural research to date the lagged effect of output on research appears to be shorter though still between ten and twelve years in this article we analyze the empirical relationship between public sector agricultural research and agricultural output our interest in this question was spurred on two fronts first emphasis of the contemporary economic literature has shifted from an analysis of the consequences of technical change to an explanation of the observed rate and direction of inventive activity a substantial proportion of this literature has focused on appropriable technologies originating in the private sector and remained largely silent on related issues in the public sector here we analyze the dynamics of public sector research in particular publicly sponsored agricultural research in the

demand and innovation schmookler re examined schmookler s demand pull hypothesis implying that innovation is a function of market demand has been widely accepted re reading schmookler s invention and economic growth we discover a statistical inadequacy re estimating his cross section results in a different way we find somewhat lower coefficients moreover the direction of causality appears to be far from obvious an independent cross sectional test of the schmookler hypothesis in the netherlands based on r d instead of patent data shows similar results the relationship between indicators of demand and innovation turns out to be generally weaker but in most cases still significant and the results suggest that there is a simultaneous relationship between demand and innovation the latter may be explained by the concept of the innovation multiplier which has implications for macro economic modelling 1 re reading schmookler schmookler s 13 finding of a strong relationship between investment in capital goods users industries and patent applications by capital goods producing sectors has been generally accepted by economists as evidence that patenting is a function of effective demand demand pull hypothesis quite a number of case studies have followed schmookier s seminal work but there have been

local demand pull policy and energy innovation evidence from the solar photovoltaic market in china abstract market demand is an important driver for inducing innovation with many empirical studies supporting the demand induced innovation hypothesis critiques of such studies however emphasize that new empirical evidence that can address existing empirical challenges is needed furthermore existing literature disagrees about whether the locus of demand pull policy matters in this paper we use empirical evidence from the distributed solar photovoltaic pv market in china to address the following questions 1 is there evidence of demand induced innovation 2 does the effect of local demand pull policy differ from the effect of non local demand pull policy on demand induced innovation to address these questions we develop and analyze an original database of pv balance of system bos patents in the distributed pv market filed between 2005 and 2014 in china our results support the demand induced innovation hypothesis and suggest that only local demand significantly induces pv bos innovations in the distributed pv market in china the different effects of local demand and non local demand emphasize the importance of local markets and local policies lending some support to bottom up approaches to clean energy governance

food beliefs and food supply chains the impact of religion and religiosity in israel abstract this paper demonstrates that religion and religiosity affect norms which affect food consumption patterns and production heterogeneity and asymmetric information lead to multiple certification channels as well as multiple supply chains major supply chains may address multiple constituencies that are secular or less religious technological change affects norms and thus the food system we obtain these results by analyzing the food systems for meat products in israel where there are three religions jews muslims and christians and people assign themselves three levels of religiosity secular conservative and orthodox israel has multiple kosher and halal certifiers and several specialized supermarket chains for orthodox groups its main supermarket chains serve secular and some conservative segments the immigration of secular jews from russia led to the proliferation of non kosher supply chains and products and increased consumption of pork new technologies and higher incomes led to emergence of fast food chains serving orthodox jews that had previously tended to eat at home

farmers financing of agricultural research in israel abstract agricultural research is mostly a public undertaking in israel as in many other countries farmers participate in the finance of research through taxes imposed by farm organizations on the marketed products farmers contribution ranges from 8 of research outlay in tomatoes to 79 in cotton strength of organization and ease of collection were the major factors affecting this share in general as inflation eroded the real value of government s finance the farmers increased their share representatives of farmers organization participate in the bodies that approve grants to proposed research projects it was found that the higher the share of farmers finance the larger the part of short term research directed at immediate outcomes and the smaller the part of long term more basic research the tendency of the farmers to prefer short term applicable research may reflect both their familiarity with practical problems and a comparatively high degree of risk aversion it is not clear how farmers participation in the direction of research which is based on their financial contribution affects the efficiency of resource allocation to the agricultural sciences

tfp growth in british and german manufacturing 1950 1996 the paper considers the accuracy of traditional tfp growth estimates using an econometric methodology which takes account of scale economies fixed factors of production and adjustment costs to reveal underlying pure technological change the results suggest that these biases vary substantially over time but do not impact heavily on anglo german comparisons in both countries the early post war years are a period when adjustment costs from a rising supply price of capital goods hold down tfp growth below that which could have accrued from pure technological progress as might be expected this problem largely disappeared in the later globalization period

on the nature of technologies knowledge procedures artifacts and production inputs in the most general terms a technology can be seen as a human constructed means for achieving a particular end such as the movement of goods and people the transmission of information or the cure of a disease these means most often entail procedures regarding how to achieve the ends concerned particular bits of knowledge artifacts and of course specific physical inputs necessary to yield the desired outcomes in fact the procedures and the underlying knowledge they draw upon the physical and intangible inputs implicated and the performance characteristics of outputs are different but complementary aspects of what technology is these things are the object of this short essay copyright the author 2009 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

the influence of market demand upon innovation a critical review of some recent empirical studies abstract a number of recent empirical studies of technical change at the level of the individual firm have concluded that market demand is the dominant influence upon the innovation process calling forth innovations in market economies the pace of innovation in the private sector heavily influences the growth of national output and productivity and these studies and their conclusions have therefore received much attention having been extensively quoted in discussions of appropriate government policy for the encouragement of innovation this paper reviews a number of these studies and concludes that their findings and the interpretations of their findings in the secondary literature are seriously flawed and in many cases invalid the proposition that market demand governs the innovation process is by no means conclusively demonstrated in these studies and they are therefore inadequate and inappropriate guides for the formulation of policy most of the studies examined employ a working definition of demand factors which is so broad as to embrace a range of possible influences upon innovation which should more properly be classified elsewhere the concept of demand utilized in these studies bears little resemblance to the more restrictive and precise definition of market demand found in economics in addition the phenomena analyzed in these studies are a very heterogeneous lot the studies do not address identical empirical questions and their findings are as a result neither uniform nor unambiguous both demand and supply side influences are crucial to understanding the innovation process and it is the exclusive preoccupation with only one set of these forces which is criticized in this paper some implications of the criticism for government policy toward innovation are discussed in the conclusion

quantile estimates of the impact of r d intensity on firm performance this paper investigates the relationship between initial research and development r d intensity and firm growth using a unique data set for firms with r d activities in austria during the period 1995 2006 results based on the least absolute deviation lad estimator show that initial r d intensity has a positive and significant impact on both employment and sales growth in the subsequent 2 years quantile regressions for each cross section reveal that the impact of r d intensity is significant from 0 3 to the highest quantile of the conditional distribution of employment growth furthermore the elasticity of employment growth with respect to r d intensity is highest for firms at or slightly below the median of the distribution of firm growth finally we find that the impact of r d decreases significantly over time

profits r d and innovation a model and a test in this article we investigate both conceptually and empirically the relationships between three interconnected elements of the schumpeterian engine of progress the ability of industries rd the ability of innovations to lead to high entrepreneurial profits the commitment of industries to invest profits in further technological efforts we build a simultaneous three equation model with appropriate lags and we test it at industry level for 38 manufacturing and service sectors on eight european countries over two time periods from 1994 to 2006 the results show that the model effectively accounts for the dynamics of european industries

production growth and business cycles ii new directions abstract this paper outlines new directions for investigations of real business cycle models consideration of stochastic growth of exogenous and endogenous forms analysis of suboptimal outcomes arising due to externalities of distorting taxes and implications of labor market heterogeneity

is demand pulled innovation equally important in different groups of firms previous empirical literature has tested the demand pull hypothesis and found that innovation may be driven by output using a balanced panel of 216 italian manufacturing firms 1995 2000 and checking for the path dependent nature of r d we find a role of sales in inducing r d however the demand pull effect plays a varying role for different sub samples of firms exporting firms liquidity constrained firms not subsidised firms and those not heading a group seem to be sensitive to sales in deciding r d these results have been obtained using a least squares dummy variable corrected estimator a recent panel data technique suitable for small samples

estimating parameters of real business cycle models abstract the calibration technique is the most common procedure to match the data generated from an equilibrium business cycle model with actual macroeconomic time series this paper goes a step further and tests and applies a maximum likelihood procedure in combination with the simulated annealing to estimate the parameters of a baseline rbc model from u s macroeconomic time series data the procedure is tested on a simulated data set where the parameters are known and then applied to u s time series data this permits us to evaluate the efficiency of the procedure and the extent to which the rbc model is a good representation of macroeconomic data

accounting for innovation and measuring innovativeness an illustrative framework and an application the purpose of this paper is to propose and illustrate an accounting framework for innovation we characterize the intensity of innovation by a sales weighted measure of innovation the share of sales in innovative products but other output indicators of innovation could be considered as well comparing statistics on the share of innovative sales across countries industries or firms measures but does not explain the intercountry interindustry or interfirm differences in innovation intensity to have a more meaningful basis of comparison we need a model if an exact model of innovation in its various dimensions existed and if we knew it we would be able to understand fully why innovation differs among countries industries or firms of course such a model does not exist nevertheless it is worth trying to account for innovation differences if only very roughly in such an endeavor what remains to be explained is as important to consider as what can be explained because it reflects the extent of innovative ability or capacity or innovativeness to motivate our approach better and make it more explicit we find it appealing to draw a comparison with the standard framework for growth accounting and the underlying model of a production function production output is viewed as resulting from a process of transformation of inputs into output that can be represented and analyzed in terms of a production function based on the production function an accounting framework can be constructed in which changes in output between periods years decades or differences between spatial units firms industries countries are ascribed to changes or differences in the inputs and in a residual that is known as total factor or multifactor productivity tfp or mfp or simply productivity likewise innovation output can be viewed as resulting from innovation inputs such as r d efforts and other contextual determinants such as the pressure of competition this linkage can be represented in terms of an innovation function and an innovation accounting framework on the basis of which changes in innovation output between periods or differences between spatial units can be ascribed to changes or differences in the factors of innovation and in a residual that we call innovativeness or the unexplained ability to turn innovation inputs into innovation output innovativeness is thus to innovation what tfp is to production innovativeness is conditional on a model of an innovation function and a set of factors of innovation just as tfp is conditional on an assumed specification of the production function and measured factors of production both correspond to omitted factors of performance such as technological organizational cultural or environmental factors and to other sources of misspecification errors although tfp is commonly interpreted as being mainly an indicator of technology the produc

statistical estimation and moment evaluation of a stochastic growth model with asset market restrictions abstract this paper estimates the parameters of a stochastic growth model with asset market and contrasts the model s moments with moments of the actual data we solve the model through log linearization along the line of campbell 1994 journal of monetary economics 33 3 463 and estimate the model without and with asset pricing restrictions as asset pricing restrictions we employ the riskfree interest rate and the sharpe ratio to estimate the parameters we employ as in semmler and gong 1996a journal of economics behavior and organization 30 301 a ml estimation the estimation is conducted through the simulated annealing we introduce a diagnostic procedure which is closely related to watson 1993 journal of political economy 101 6 1011 and diebold et al 1995 technical working paper no 174 national burea of economic research to test whether the second moments of the actual macroeconomic time series data are matched by the model s time series several models are explored the overall results are that sensible parameter estimates may be obtained when the actual and computed riskfree rate is included in the moments to be matched the attempt however to include the sharpe ratio as restriction in the estimation does not produce sensible estimates the paper thus shows by employing statistical estimation techniques that the baseline real business cycle rbc model is not likely to give correct predictions on asset market pricing when parameters are estimated from actual time series data

leverage time preference and the equity premium puzzle abstract we re examine the mehra and prescott 1985 model a combination of the time preference factor greater than one and reasonable leverage ratios in the equity market resolve the equity premium puzzle such parameter values can be consistent with finite expected utility and a positive risk free rate of interest rate the model performs better for the mp target values than for economically reasonable variations around those values

the roles of science in technological innovation abstract one of the central issues in science policy during the past decade has been the extent to which the national levels of expenditure on scientific education and research influence the standard of living this paper provides empirical evidence to show that the pay off from this investment in science is more complex and indirect than previously supposed

demand side vs supply side technology policies hidden treatment and new empirical evidence on the policy mix this paper provides new empirical evidence about the impact of various technological policies upon firms innovative behaviour we take into consideration the role of policies for innovative activities and we focus on their interaction while supply side policies such as r d subsidies and tax credits have been both extensively discussed in the literature and empirically investigated the analysis of innovative public procurement is a growing trend in the literature which still lacks robust empirical evidence in this paper we replicate the existing results on supply side policies surmise fresh empirical evidence on the outcome of innovative public procurement and address the issue of possible interaction among the various tools when controlling for the interaction with other policies supply side subsidies cease to be as effective as reported in previous studies and innovative public procurement seems to be more effective than other tools the preliminary evidence suggests that technology policies exert the highest impact when different policies interact

inventor networks in renewable energies the influence of the policy mix in germany technological change and gains in efficiency of renewable power generation technologies are to a large extent driven by governmental support various policy instruments that can broadly be categorized as technology push demand pull or systemic constitute part of the policy mix for renewable energies our goal is to gain insights into the influence of this policy mix on the intensity and organization of inventive activities for wind power and photovoltaics in germany since the 1980s we examine the effect of different instruments on the size and structure of co inventor networks based on patent data our results indicate notable differences between the technologies the network size for wind power is driven by technology push and systemic instruments while in photovoltaics demand pull is decisive for network growth by and large the instruments complement each other and form a consistent mix of policy instruments the structure of the networks is driven by demand pull for both technologies systemic instruments increase interaction especially in the wind power network and are complementary to demand pull in fostering collaboration

patent quality and research productivity measuring innovation with multiple indicators we analyse the determinants of the decline in research productivity using panel data on manufacturing firms in the us for the period 1980 93 we focus on three factors the level of demand the quality of patents and technological exhaustion we develop an index of patent quality using detailed patent information and show that using multiple indicators substantially reduces the measured variance in quality research productivity at the firm level is inversely related to patent quality and the level of demand as predicted by theory and patent quality is positively associated with the stock market value of firms

from government to market and from producer to consumer transition of policy mix towards clean mobility in china abstract this paper proposes a new typology that classifies innovation policy instruments into two dimensions government selection versus market selection and producer orientation versus consumer orientation such a typology articulates the importance of consumer behavior in the policy design for a transition and the relevance for the market to select target subjects of policy during the deployment stage of clean technology innovation we apply this typology to policy instruments of china s new energy vehicle nev industry between 1991 and 2015 in order to explain the industry s rapid growth the focus of china s policy mix has transited from government selection to market selection and from producer orientation to consumer orientation other than the new typology this paper traces the entire history of policy transition within china s nev industry and finds the transition to be a result of policy learning thus contributing to future empirical studies of this industry
