frictionless commerce a comparison of internet and conventional retailers there have been many claims that the internet represents a new nearly frictionless market our research empirically analyzes the characteristics of the internet as a channel for two categories of homogeneous products books and cds using a data set of over 8 500 price observations collected over a period of 15 months we compare pricing behavior at 41 internet and conventional retail outlets we find that prices on the internet are 9 16 lower than prices in conventional outlets depending on whether taxes shipping and shopping costs are included in the price additionally we find that internet retailers price adjustments over time are up to 100 times smaller than conventional retailers price adjustments presumably reflecting lower menu costs in internet channels we also find that levels of price dispersion depend importantly on the measures employed when we compare the prices posted by different internet retailers we find substantial dispersion internet retailer prices differ by an average of 33 for books and 25 for cds however when we weight these prices by proxies for market share we find dispersion is lower in internet channels than in conventional channels reflecting the dominance of certain heavily branded retailers we conclude that while there is lower friction in many dimensions of internet competition branding awareness and trust remain important sources of heterogeneity among internet retailers

you can t save alone commitment in rotating savings and credit associations in kenya abstract this article examines one reason why individuals develop and maintain local level financial savings organizations known as rotating savings and credit organizations or roscas economic theories suggest that individuals form roscas to finance the purchase of a lumpy durable good in response to intrahousehold conflict over savings or to provide themselves with insurance the article proposes an additional hypothesis for rosca participation saving requires discipline and some roscas may be formed to provide a collective mechanism for commitment in the presence of time inconsistent preferences data from 70 roscas located in western kenya indicate that the commitment hypothesis is plausible and broadly consistent with the design and patterns of participation in these roscas as many rosca participants put it you can t save alone

pricing under quality of service uncertainty market segmentation via statistical qos guarantees abstract this article examines how performance contingent pricing schemes with long term statistical performance guarantees can be applied to many it services we study two forms of performance contingent pricing with rebate proportional to failure rate and fixed rebate for below threshold performance we show that threshold performance contingency pricing can increase both profits and fairness customers who receive higher benefits pay higher effective price relative to standard pricing but an even better solution is to offer a menu of performance guarantees this can increase the firm s profit and segment the market only service providers whose performance level is sufficiently better than the industry standard can benefit from this pricing mechanism

technology acquisition with technological progress effects of expectations rivalry and uncertainty abstract we study the effect of expectations regarding technological progress on a firm s technology adoption decision in a duopoly new generation technologies become available one in each period with successive generations representing better and better performance a game theoretic framework is used involving two identical firms competing in the same market over two periods it is shown that expectations retard adoption of the first period technology it is also shown that an asymmetric equilibrium results in higher social welfare and that more investment does not necessarily mean higher levels of welfare uncertainty is shown to have either no effect or a negative effect on the adoption of the current technology when nash equilibrium holds however when subgame perfect equilibrium holds uncertainty has a more complicated effect and numerical examples show that it may even encourage the adoption of the current technology relative to the deterministic equilibrium

the name your own price channel in the travel industry an analytical exploration name your own price nyop retailers such as priceline offer an alternative distribution channel for service providers in the travel industry such as airlines hotels and car rental companies our research employs an analytical model to identify and understand key trade offs driving the decision by a service provider to employ an nyop channel assuming that such a channel is available this decision requires the existence of forces that counteract the adverse consequences of cannibalization of sales through traditional posted price channels our analysis provides some insight into these forces contracting with the nyop retailer facilitates market segmentation and price discrimination and allows for disposal of excess capacity after meeting business travel demand however the cost of this flexibility is that the service provider can no longer credibly precommit to maintaining high prices when there is unsold capacity also when contracting with an independent retailer the service provider is unable to extract the entire revenue generated from nyop consumers a key insight from our model is that the rationale for contracting with an nyop retailer is driven by the uncertainty in business travel demand not the expectation of excess capacity indeed all else equal the larger the capacity the less likely it is that contracting with an nyop retailer is the right decision on the part of the service provider

prices and price dispersion on the web evidence from the online book industry using data collected between august 1999 and january 2000 covering 399 books we examine pricing by thirty two online united states based bookstores at the aggregate level we find that both advertising and competitive structure had the predicted effects more competition led to lower prices and to lower price dispersion holding competitive structure constant more widely advertised items also had lower prices at the firm level we observe considerable heterogeneity in behavior firms had differentiated or attempted to differentiate on dimensions such as brand price and selection

technological expectations and adoption of improved technology abstract attention is focused upon the adoption demand rather than the creation supply of new technology which improves from time to time based on the expected flow of technological progress over which the firm demander has no control it must decide either to adopt the current best available technology or to postpone adoption the distinguishing features of the model are that more than one technological innovation is anticipated and expectations about the likelihood of such innovations are revised as time passes since the last innovation our analysis shows that the firm will adopt the current best practice if its technological lag exceeds a certain threshold moreover as time passes without new technological advances it may become profitable to purchase a technology that has been available even though it was not profitable to do so in the past

managing online auctions current business and research issues the internet s computational power and flexibility have made auctions a widespread and integral part of both consumer and business markets though online auctions are a multi billion dollar annual activity with a growing variety of sophisticated trading mechanisms scientific research on them is at an early stage this paper analyzes the current state of management science research on online auctions it develops a broad research agenda for issues such as the behavior of online auction participants the optimal design of online auctions the integration of auctions into the ongoing operation of firms and the use of the data generated by online auctions to inform future trading mechanisms these research areas will draw from applied and theoretical work spanning management science economics and information systems

the reaper and the scanner indivisibility led incremental innovations and the adoption of new technologies widespread adoption of a new capital embodied technology requires a continu ous flow of incremental innovations a few of them address the key problem of indivisibility by making renting the new machine a viable alternative to buying it or by dividing it up into modular elements such incremental innovations differ from the learning by doing effects usually considered by diffusion models and greatly affect the structure of the adopting industry the case for keeping them in due account is made by revisiting paul david s classic paper on the mccormick reaper by criticising the subsequent evolution of threshold models of adoption and by summarising my own findings on the diffusion of electronic pre press devices

measuring the frictional costs of online transactions the case of a name your own price channel we study the offers submitted by consumers to a large name your own price nyop online retailer a distinctive feature of this retailer is that it allows consumers to repeatedly submit offers on one and the same product while consumers could identify the threshold price the minimum price for which the retailer is willing to sell by incrementing their offer in small steps in each consecutive round such a strategy would require them to go through many additional online transactions we define frictional cost as the disutility that the consumer experiences when conducting an online transaction such as submitting an offer thus in our setting consumers trade off a direct financial value lower price for frictional costs based on a consumer choice model capturing this trade off we use the observed consumer behavior to reconstruct the frictional cost parameters for the consumers in our sample we show that perhaps contrary to the general wisdom frictional costs in electronic markets are substantial with median values ranging from eur 3 54 for a portable digital music player mp3 to eur 6 08 for a personal digital assistant pda we find that consumers who have gathered experience with the nyop channel in previous transactions exhibit lower frictional costs than consumers who use the channel for the first time surprisingly sociodemographic variables do not help to explain the variation in frictional costs

credit constraints credit unions and small scale producers in guatemala abstract efficient and equitable development outcomes may depend in part on whether formal financial institutions leave low wealth producers tightly constrained in their access to credit if so can cooperative institutions efficiently relax these constraints these issues are explored using survey data gathered from 950 small scale producer households in areas of guatemala with market oriented credit unions that mobilize savings and make unsubsidized loans nonprice rationing by banks is found to be common among lower wealth households while credit unions relax credit constraints for a significant portion of those rationed by banks but not the poorest of the study households

sectoral patterns of technical change towards a taxonomy and a theory abstract the purpose of the paper is to describe and explain sectoral patterns of technical change as revealed by data on about 2000 significant innovations in britain since 1945 most technological knowledge turns out not to be information that is generally applicable and easily reproducible but specific to firms and applications cumulative in development and varied amongst sectors in source and direction innovating firms principally in electronics and chemicals are relatively big and they develop innovations over a wide range of specific product groups within their principal sector but relatively few outside firms principally in mechanical and instrument engineering are relatively small and specialised and they exist in symbiosis with large firms in scale intensive sectors like metal manufacture and vehicles who make a significant contribution to their own process technology in textile firms on the other hand most process innovations come from suppliers these characteristics and variations can be classified in a three part taxonomy based on firms 1 supplier dominated 2 production intensive 3 science based they can be explained by sources of technology requirements of users and possibilities for appropriation this explanation has implications for our understanding of the sources and directions of technical change firms diversification behaviour the dynamic relationship between technology and industrial structure and the formation of technological skills and advantages at the level of the firm the region and the country

an empirical analysis of digital music bundling strategies we use panel data on digital song and album sales coupled with a quasi random price experiment to determine own and cross price elasticities for songs and albums we then develop a structural model of consumer demand to estimate welfare under various policy relevant counterfactual scenarios this approach represents an early application of the big data management paradigm within the media industries and provides managers with detailed guidance on optimal pricing and marketing strategies for digital music our results show that tiered pricing coupled with reduced album pricing increases revenue to the labels by 18 relative to uniform pricing policies traditionally preferred by digital marketplaces while also increasing consumer surplus by 23 thus optimal tiered pricing can yield a pareto improvement over the prior status quo additionally our results indicate that even without tiered pricing unbundling albums outperforms album only pricing policies that dominated the era of physical cd cassette sales this paper was accepted by alok gupta special issue on business analytics

joint bidding in the name your own price channel a strategic analysis in this paper we study the name your own price nyop channel we examine theoretically and empirically whether asking consumers to place a joint bid for multiple items rather than bid one item at a time as practiced today can increase nyop retailers profits relatedly we also examine whether allowing consumers to self select whether to place a joint bid or itemwise bids increases retailers profits and consumers surplus we construct a dynamic model that incorporates both demand uncertainty and supply uncertainty to address these issues our theoretical analysis identifies the conditions under which joint bidding can increase both nyop retailers profits and consumers surplus we find that some consumers might bid more for the very same items when they place joint bids the increase in bid amount is related to the fact that joint bidding reduces the chance of mismatch between nyop retailers costs and consumer bids we conducted a laboratory study to assess the descriptive validity of some of the

cost structure and technical change in rural banking abstract using the multi product translog cost function this paper examines the cost structure and technical change occurring within the novel ghanaian rural banks the results of the seemingly unrelated error components model indicate substantial unexploited economies of scale in individual products as well as in overall intermediation there is presence of pairwise complementarity between loans and government securities and between deposits and government securities but absence of pairwise complementarity between loans and deposits overall capital using and labour saving technical change has occurred but efficiency loss in deposit mobilization outweighs the efficiency gains in government securities and lending activities operation of agencies reinforces the overall efficiency loss the rural banks must not be hindered from expanding but in any growth strategy deposit mobilization should take a central position and the cost of operating agencies watched closely

managing product families the case of the sony walkman abstract success in fast cycle industries e g consumer electronics can depend both on rapid model replacement and on model longevity although sony was as fast as any of its chief competitors in getting new models to market an important explanation for the wide variety of models offered by the firm is the greater longevity of its key models this finding adds an important insight to the conventional literature on time based competition which emphasizes rapid innovation exclusively sony s special understanding of the us market enabled it to respond more effectively to life style differences by locating industrial designers in its key markets sony s strong design capability and effective division of labor engineers lead generational and incremental projects industrial designers and market personnel lead topological projects allow for parallel model development investment in manufacturing flexibility amortized over multiple models within the product family make the rapid model changeover possible

technology use and plant closure abstract this paper aims to contribute to the empirical literature on industrial demography it analyzes a stratified sample of the italian metalworking industry composed of 810 plants with more than 10 employees it considers plant closure over the period 1989 1997 probit type econometric models are estimated in order to provide evidence on the explanatory factors of the likelihood of closure with special attention being devoted to technological variables the paper extends previous empirical results along a number of directions first in spite of the fact that use of advanced technologies especially in the design and engineering sphere favors survival remarkable differences do emerge between different individual technologies ceteris paribus plants having adopted technologies characterized by sizable product specific investments turn out to be less likely to be shut down in addition the ownership status of plants is found to influence the probability of closure likelihood of survival is lower for plants that belong to multi unit organizations than for those owned by single plant firms even though the difference between the two plant categories decreases with plant size altogether such results point to the relevance of irreversibility and sunk costs for understanding exit behavior

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

the intra firm diffusion of new process technologies the study of intra firm diffusion has largely been neglected and the limited extant literature overwhelmingly relies upon uncertainty reduction via information spreading or epidemic learning as the main driver in this paper an alternative approach is taken whereby the intra firm diffusion of new process technologies reflects the profitability of new technology adoption as proxied by firm characteristics the approach is tested using data relating to the diffusion of computer numerically controlled machine tools within firms in the uk engineering and metalworking sectors the empirical analysis does not reject the hypothesis that profitability considerations are important with a number of firm characteristics being isolated as of special relevance including firm size and the use of complementary technologies and managerial techniques however there is little support for the traditional epidemic effect

complementarity and cumulative learning effects in early diffusion of multiple technologies this paper concentrates on the contextual diffusion of flexible automation production and design engineering technologies in the italian metalworking industry the authors use duration data analysis with explanatory covariates to point out the role of complementarities between the technologies examined and learning by using effects matured with experience of previously available technologies in shaping diffusion paths the impact of industry and plant specific control variables as well as that of the stock of previous adopters on adoption probabilities is also taken into account in addition the authors analyze duration versus calendar time dependence of adoption probabilities copyright 1995 by blackwell publishing ltd

the impact of formal finance on the rural economy of india india has systematically pursued a supply led approach to increasing agricultural credit its objectives have been to replace moneylenders to relieve farmers of indebtedness and to achieve higher levels of agricultural credit investment and output india s success in replacing moneylenders has been outstanding between 1951 and 1971 their share of rural credit appears to have dropped from more than 80 percent to 36 percent it may have dropped to as low as 16 percent by 1981 but that estimate is disputed still institutional credit is far from reaching all farmers only about a quarter of cultivators borrow and no more than 2 percent take out long term loans most small farmers have little access to credit and long term credit goes mostly to large farmers overall farm debt has probably not increased sharply in real terms as formal credit has primarily substituted for credit from other sources moreover with the rapid growth of commercial banks in the 1970s the system mobilized more deposits than it lent in rural areas in 1981 of course enhanced deposit services are a useful service of the rural population but one must ask what has been the impact of heavy rural credit and better financial services on agricultural investment production and rural incomes the authors econometric results suggest that the rapid expansion of commercial banks in rural areas has had a substantially positive effect on rural nonfarm employment and output the availability of better banking facilities appears to have overcome one of the obstacles to locating nonfarm activities in rural areas expanded rural finance has had less of an effect on output and employment in agriculture than in the nonfarm sector the effect on crop output has not been great despite the fact that credit to agricluture has greatly increased the use of fertilizer and private investment in machines and livestock there has been more impact on inputs than on output so the additional capital investment has been more important in substituting for agriclutural labor than in increasing crop output but overall rural credit and expansion of the rural financial system have had a positive effect on rural wages creating nonfarm jobs has apparently added more to total employment than the substitution of capital for labor has subtracted it in agriculture so wages have risen even for agricultural workers albeit modestly the supply led approach to agricultural credit that has been pursued for three decades has clearly benefited current borrowers and farm households formerly indebted to moneylenders it has also spurred fertilizer use and investment in agriculture it has been less successful in generating viable institutions and has failed to generate agricultural employment the policy s costs to india s government have been high as portfolio losses associated with poor repayment ultimately have to be borne by the government or one of its institutions under optimistic assumptions the benefits of the agricultural income are at best no more than 13 percent higher than the cost to the government of the extra agricultural credit if assumptions about the cost of supplying the credit and about repayment rates are less optimistic the social costs and the costs to the government of providing the credit would have exceeded the benefits in agricultural income the expansion of commercial banks to rural areas paid off in nonfarm growth employment and rural wages the question is could these benefits have been achieved without imposing agricultural credit targets on the commercial banks and credit cooperatives or did the commercial banks expand only because they were forced to lend to agriculture the authors could not answer these questions with the data at hand

household sectoral choice and effective demand for rural credit in india an analysis of the icrisat data from three indian villages raises concern about the extent of rationing mechanism inhibiting the spread of formal credit in rural india where a significant proportion of households do not have any outstanding loan or borrow from the informal sector only a limited dependent econometric analysis of the factors jointly determining household sectoral choice and effective demand for informal loan conditional on whether a formal loan is available suggests that compared to formal loan easy and adequate access and prompt recovery are significant determinants of the popularity and viability of informal rural credit among sample households also some households substitute labour income to ease the extent of credit thus rationing of the formal credit is not the only factor inhibiting the spread of formal credit in the study villages

soil quality and fertilizer use rates among smallholder farmers in western kenya studies of fertilizer use in sub saharan africa have been dominated by analyses of economic and market factors having to do with infrastructure institutions and incentives that prevent or foster increased fertilizer demand largely ignoring how soil fertility status conditions farmer demand for fertilizer we apply a switching regression model to data from 260 farm households in western kenya in order to allow for the possibility of discontinuities in fertilizer demand based on a soil carbon content scc threshold we find that the usual factors reflecting liquidity and quasi fixed inputs are important on high scc plots but not on those with poorer soils external inputs become less effective on soils with low scc hence the discernible shift in behaviors across soil quality regimes for many farmers improved fertilizer market conditions alone may be insufficient to stimulate increased fertilizer use without complementary improvements in the biophysical conditions that affect conditional factor demand

implications of expected changes in the seller s price in name your own price auctions the seller s threshold price in name your own price auctions varies over time however consumers must bid without knowing when these variations occur because the threshold price is unobservable to them this paper uses an analytical model and laboratory auctions to explore how the frequency of changes in the threshold price impacts consumer bidding behavior in name your own price auctions in particular we consider how the frequency of these expected changes affects the optimal pattern of bid sequences e g strictly increasing over time or following a nonmonotonic pattern we find that when the probability of a price change is moderate consumers may have an incentive to use nonmonotonic bidding patterns rather than steadily increasing their bids over time consumers will at some point in the bid sequence decrease their bid however when the expected probability of a price change is very low or very high consumers do not have an incentive to use nonmonotonic bidding patterns interestingly impatient bidders are more likely to decrease their bids at some point in the bid sequence than patient bidders finally we find that more frequent price changes may increase customer satisfaction

rural financial markets in developing countries their use and abuse until recently the use of agricultural credit as a developmental tool seemed clear and straightforward most concerned people believed that increases in the volume of cheap credit were necessary to boost agricultural production and that the rural poor could be brought into the mainstream of development through supervised credit programs it seemed that certain ideal types of rural credit institutions offered the promise of meeting farmers credit needs and that experience in the industrialized countries with cooperatives and specialized agricultural finance institutions could be effectively transplanted to low income countries this collection of readings highlights facets of rural financial markets that have often been neglected in discussions of agricultural credit in developing countries it moves beyond a narrow concern with the simple provision of credit to a broad consideration of the performance of rural financial markets and of ways to improve the quality and range of financial services for low income farmers it reflects new thinking on the design administration evaluation and policy framework of rural finance and credit programs in developing countries

an evolutionary pattern of innovation diffusion the case of flexible automation abstract the aim of this paper is to provide evidence supporting an evolutionary model of the process of innovation diffusion relying on an extensive field study the paper analyses the pattern of adoption of the entire set of innovations deriving from the flexible automation paradigm on the part of a large sample of italian metalworking firms owing to the relevance of the technology examined and to the size of the sample the case illustrates quite representatively the dynamics of the early stage of development of radical and complex innovations the main results of the paper confirm the importance of firm size and market structure to explain the characteristics of the innovation diffusion process at the same time they emphasize that the localized search procedures on the part of potential users involve a step by step approach to adoption namely the technological and organizational profile of firms turns out to play a decisive role in favouring diffusion moreover empirical support is provided for the existence of persistent market disequilibria along the diffusion paths witnessed by the extent of the retrofitting phenomenon

the development and use of machine tools in historical perspective abstract improvements and diffusion of machine tools have had a major impact on productivity in manufacturing industry since the industrial revolution the impact has been both direct and indirect the direct impact consists of rising labor productivity through the use of faster more accurate more mechanized machines and of the higher capital productivity through higher operating rates greater reliability and higher utilization rates the indirect impact arises as the use of new or improved machine tools has necessitated or facilitated organizational changes affecting both labor capital raw materials and energy the magnitude of these impacts has varied over the years with the areas of application as new production methods have made possible entirely new products or lowered the cost of existing products sufficiently to create new markets the first part of the paper contains a review of the historical development of machine tool technology since the industrial revolution paying particular attention to the role of interaction between producers and users of machine tools the second part focuses on the way in which recent development differs from that in earlier periods in particular it is found that the major changes in machine tool technology from the so called american system of manufactures in the early 19th century to the development of detroit automation in the 1950s have tended to improve mass production methods by contrast the development of numerical control beginning in 1948 has opened up the possibility of extending industrial production methods and automation to areas previously characterized more by handicraft methods even though this technology is not yet fully utilized it is clear that the economics of industrial production has been revolutionized by the cost reduction of small scale production relative to large scale and the degree of flexibility offered by the technology the third section of the paper deals with the present development trends particularly discussing the increasing importance of flexibility and the shifting emphasis from development of individual pieces of machinery to integration and control of entire manufacturing processes i a through the use of industrial robots the reasons for the need for greater flexibility in manufacturing are also identified

the problem of transaction costs in group based microlending an institutional perspective abstract to be financially viable group based microlending needs to economize on transaction costs for both lenders and borrowers group lending programs vary in their transaction cost characteristics depending on their specific credit delivery arrangements and social contexts this article illustrates these arguments by examining the challenges faced by various group lending programs worldwide it also examines how social capital or the lack of it affects the transaction costs and operations of three typical group lending arrangements group loan with joint liability individual loan with joint liability and individual loan with individual liability

technological regimes and innovation in services the case of the italian banking industry abstract in this paper we propose a conceptual model to analyse innovations originating from the diffusion of information technologies in the banking sector we argue that technical change in this industry exhibits a revolutionary character a distinction is made between the mass automation regime focusing mainly on the mechanization of back office procedures in the 1960s and 1970s and the smart automation regime originating from the introduction of distributed data processing and network technologies and centered around the supply of electronic banking services a theoretical model is developed which emphasizes the crucial role played by demand pull variables in stimulating innovative behaviour under the smart automation regime in contrast limited importance is attributed to cumulative and learning by doing effects relating to back office automation at least for banks endowed with sufficient absorptive capacity the theoretical hypotheses are tested through an econometric analysis of the determinants of the innovative behaviour in electronic payment systems of a sample of italian commercial banks

the thai rural credit system public subsidies private information and segmented markets thailand has sought to increase farmers access to credit by government intervention in 1966 it created a government agricultural bank to lend solely to farm households and beginning in the late 1970s it required commercial banks to lend heavily in the rural sector either directly or by making deposits in the agricultural bank the result was an enormous expansion of credit in the rural sector but because formal lenders were either unable or unwilling to solve the information problems involved in the broad range of rural credit transactions the informal credit sector wbich charged interest rates many times higher than the formal sector continued to thrive using household surveys and surveys of moneylenders this article provides a detailed analysis of the ways in which lenders in the informal sector have solved the information problems of providing credit the authors argue that the informal sector is competitive and that high interest rates reflect high information costs not the scarcity of funds this article reports on a set of investigations of the impact of thai government policies to expand bank lending in the rural sector their purpose was to increase farmers access to capital and reduce their dependence on informal lenders fifteen years after the principal government measures were introduced we hope to be able to answer several questions how has the expansion of formal sector lending affected the informal sector did the increase in the supply of formal credit reduce the business of informal lenders and lower interest rates in the informal market what has been the performance of the formal credit system in terms of coverage efficiency and incidence lacking time series data on the informal sector we cannot give a direct answer to these questions but we can with confidence say that the informal lenders are still very much alive by examining the behavior of the rural credit market at the present time we can throw an indirect light on what transpired over the last fifteen years our main findings are the following on the basis of our 1984 85 survey of households and moneylenders

partial repeat bidding in the name your own price channel this paper presents an initial examination of an emerging business model the name your own price nyop channel as popularized by priceline com focusing on how to optimally structure such market interactions i ask whether it is more profitable to restrict individuals to a single bid as is currently done by priceline or conversely to allow consumers to continue bidding if the previous offer was rejected i find that both market structures yield the same expected profit in practice a single bid policy may not be perfectly enforceable especially in the internet environment because a sophisticated user can circumvent such a policy by camouflaging one s identity or otherwise manipulating the bidding procedure thus priceline s single bid restriction is likely to result in partial repeat bidding the case in which some consumers are limited to a single bid while other sophisticated users may rebid i ask whether such surreptitious bidding is detrimental to the nyop firm and find that profits are lower than if such opportunistic behavior were absent surprisingly i find that the impact of the number of repeat bidders on profits is not monotonic thus if it is prohibitively costly or logistically infeasible for the nyop firm to eliminate surreptitious rebidding behavior the firm may in fact benefit from encouraging rather than discouraging users to rebid the direction that increases profits depends on the percentage of sophisticated bidders

the adoption of new technology in the american machinery industry rees j briggs r and oakey r 1984 the adoption of new technology in the american machinery industry reg studies 18 489 504 this study examines the spread of a number of key production technologies among machinery manufacturers across the united states based on a mail and interview survey of over 600 industrial plants across the country it was found that adoption rates for these innovations varied by industrial sector organizational status of plants age and size of plants as well as by region and metropolitan characteristics of plants the findings suggest that policy makers interested in nurturing small businesses should consider technical assistance strategies that encourage the spread of innovation among firms and that high priority be given to labour training programmes in local economic development strategies at the federal level this study also suggests that the innovation potential of manufacturing belt companies should not be overlooked in any new initiatives to encourage economic re

on the diffusion of new technology a game theoretic approach this paper is an attempt at a rigorous albeit not exceedingly general analysis of the diffusion of new technology in particular consider an industry composed of two firms each using the current best practice technology the firms are assumed to be operating at nash equilibrium output levels generating a market price given demand and profit allocations when a cost reducing innovation is announced each firm must determine when if ever to adopt it based in part upon the discounted cost of implementing the new technology and in part upon the behavior of the rival firm if either firm adopts before the other it can expect to make substantial profits at the expense of the other firm on the other hand the discounted sum of purchase price and adjustment costs may decline with the lengthening of the adjustment period as various quasi fixed factors become more easily variable therefore although waiting costs the firm more in terms of foregone profits it may save money on the cost of purchasing the new technology thus the firm must weigh the costs and benefits of delaying adoption as well as take account of its rival s strategic behavior

buyer behavior under the best offer mechanism a theoretical model and empirical evidence from ebay motors abstract we use data from ebay best offer listings to analyze haggling over prices in transactions with one seller and a series of potential buyers for a limited supply product we characterize this transaction mechanism as a sequential move game to investigate buyer behavior our model suggests that a buyer s offer price increases in relations to the number of buyers who have previously made an offer on the item and the buy it now price chosen by the seller on the other hand the offer price decreases for items which have been listed on ebay for a longer period of time we empirically test our theoretical predictions using data on the sales of toyota camry cars on ebay motors the empirical evidence is consistent with our model

firm size and the adoption of flexible automation data on the diffusion of flexible automation systems in the italian metalworking industry are used to point out the role of size for the adoption of complex systemic innovations plant and firm sizes turn out to be positively correlated to adoption rates moreover adoption is more likely ceteris paribus in plants which are part of large industrial groups this pattern applies in general and is particularly remarkable for more advanced solutions in this light guidelines for industrial policies that focus on financial support the diffusion of industrial standards and the correction of asymmetries in the availability of know how and skills are proposed

price dispersion and differentiation in online travel an empirical investigation previous research has examined whether price dispersion exists in theoretically highly efficient internet markets however much of the previous work has been focused on industries with low cost and undifferentiated products in this paper we examine the presence of price dispersion and product differentiation using data on the airline ticket offerings of online travel agents otas we find that different otas offer tickets with substantially different prices and characteristics when given the same customer request some of this variation appears to be due to product differentiation different otas specialize by systematically offering different trade offs between ticket price and ticket quality minimizing the number of connections matching requested departure and return time however even after accounting for differences in ticket quality ticket prices vary by as much as 18 across otas in addition otas return tickets that are strictly inferior to the ticket offered by another ota for the same request between 2 2 and 28 of the time overall this suggests the presence of both price dispersion and product differentiation in the online travel market

innovation in rural finance indonesia s badan kredit kecamatan program abstract donor agencies and governments are committing increasing resources to microenterprise credit programs much as they earlier funded rural credit yet few programs embody the lessons from this earlier experience central java s badan kredit kecamatan program shows considerable promise in providing the access convenience and flexibility desired by poor borrowers while assuring the financial viability of the credit institution by minimizing administrative costs and imposing interest rates sufficient to cover costs and prevent capital erosion recent progress has also been made in mobilizing voluntary savings strong political support from the government has been crucial to the program s success

risk pooling through physical probabilistic selling abstract this paper investigates the impacts of a new type of probabilistic selling p s where the retailer orders specific products and package some as a discounted physical probabilistic product ppp rather than merely a virtual choice we call this p s strategy as physical probabilistic selling p p s the price gap between the specific products and the probabilistic product results in demand reshape i e some customers who originally buy specific products will switch to buying the probabilistic product which decreases aggregate demand uncertainty however the price discount decreases the profit margin considering this trade off we develop a three product newsvendor model to address the question of how to set the price for the ppp and make inventory allocation decisions we prove that there are two effects under p p s namely the risk pooling effect due to demand reshape and the risk diversification effect due to inventory flexibility with demand uncertainty p p s can improve the retailer s profit at lower inventory levels with proper demand reshape induced by the optimal price discount p p s is more profitable with smaller product differentiation higher customer price sensitivity higher demand uncertainty and lower package cost with supply uncertainty we demonstrate through numerical studies that p p s is a viable strategy to combat asymmetrical supply risk that yields higher profits and service levels

what determines success examining the human financial and social capital of jamaican microentrepreneurs abstract this research examines the performance of 215 informal microenterprises in jamaica studying the influence of human capital social capital and financial capital of the owners on their business profitability understanding the importance of particular relationships that result in successful micro businesses is important for a number of reasons first among many developing countries the growth of microenterprise provides the most visibly vibrant and growing economic activity although considerable effort and resources are being directed toward microenterprise promotion schemes empirical research on the subject is quite limited second economies in developing countries mirror many of the social and institutional problems existent in urban economically disadvantaged areas of the united states and other developed countries for these areas microenterprise may be an essential component of urban renewal and community development this study helps in identifying important characteristics of social and individual attributes that may be relevant to those attempting to strengthen this subsector finally this study seeks to provide insight into a dimension of microbusiness research for which there are limited data specifically the role that social capital plays among practicing entrepreneurs and owners this research found that different structural environments even within a singular and small economy may considerably alter the rates of return to human social and financial capital as a result the analysis of enterprises includes segmentation according to both the usage or not of employees and the sophistication of the technologies used several factors were determined to enhance the profitability of the businesses in all categories vocational training for example demonstrated consistently strong and positive effects mother s high occupational status a proxy for socioeconomic status and years of experience in the business were also consistently positive and strongly associated with increasing profits although additional starting capital played an important role for both the businesses with and without employees increasing amounts failed to differentiate the success of those firms that were already operating in the higher technological tier obtaining a small business loan acted in a similar manner enhancing the profitability of all firms except those segmented into a high technological tier one interpretation of this finding is that the role of technological choice is extremely important and appears to dwarf that of varying amounts of starting capital social capital as operationalized by frequent church attendance and marital status of the owner was found generally to increase the profitability of the business the data demonstrate that social networks play an important role in the success of these businesses and that conditions in the highest tier utilize social capital in a somewhat unique manner

analyzing literature based innovation output indicators the italian experience abstract this paper presents the results of a study on the product innovations introduced in the italian market in 1989 and reported in a selected number of trade journals the analysis of data collected by means of this literature based counting procedure confirms that r d oriented industries and large firms do not in italy have a marked competitive advantage in innovation the country appears to be instead characterized by a significant presence of consumer goods industries and small firms in innovation our data indicate a statistically significant association between trade competitiveness and strength in product innovation and show the comparatively higher capacity for product innovation of some of the industries in which italy achieves a positive performance in international trade moreover the presence of spillovers at the regional level from both private and public r d expenditures proves to be positively correlated with the development of product innovations finally small firms with fewer than 50 employees appear to be more innovative than is usually believed to be the case

firm size and technical change in a dynamic context this article investigates relationship between firm size and technical change the relationship between firm size and technical change has long been a pre occupation in the literature preceding the flurry of macroeconomic studies which followed the discovery of the residual factor by solow dennison and others although this concern goes back at least to the writings of marx it was schumpeter who first emphasized the relationship between firm size and technical change for some years the assertion of schumpeter s was widely accepted but then a number of detailed empirical studies were undertaken resting on 1950s data these began to suggest that beyond a certain size inventive activity rose less than proportionately with bigness by contrast rothwell and zegveld assembled a variety of country studies some of which suggest that small and medium sized firms are relatively invention and innovation intensive in some sectors and in some countries the purpose of this paper is to argue by illustration with a single sector computer aided design cad that the above mentioned studies reach their varying conclusions in a largely static framework thus whilst there is always a tendency towards concentration in capitalism the relationship between firm size and technical change is a dynamic one ensuring that static generalisations at any single point of time are not very helpful the article is divided into sections by section iii describes the market structure in the cad sector and analyse how this has changed over the past decade section iv analyses the nature of the barriers to entry in this sector and illustrate how these are typical of other emerging software intensive microelectronic based sectors finally section v is a return discussion on the relationship between firm size and inventive activity

collective agricultural production a solution for transition economies abstract the paper examines theoretical reasons and provides examples for productivity differences between agricultural service cooperatives and collectives service cooperatives can utilize economies of scale enhance competitiveness and provide technical information advantages that often outweighed problems of free riding low investment and excessive political intervention agricultural collectives while not adding substantial advantages are in addition associated with problems of supervision and effort supply tendencies to substitute casual workers or mechanization for regular members and low investment incentives while collective forms of organization in transition economies respond to high risk and market imperfections they do so inefficiently policies that create conditions for service cooperatives to compete may lead to large productivity gains

on the effects of consumer search and firm entry in a multiproduct competitive market this paper studies a model in which consumers search among multiple competing firms for products that match their preferences at a reasonable price we focus on how easier search possibly due to the adoption of search facilitating technologies such as the internet influences equilibrium prices assortments firm profits and consumer welfare conventional wisdom suggests that easier search creates a competition intensifying effect that puts pressure on firms to lower their prices and reduce assortments however in our model we demonstrate that search also exhibits a market expansion effect that encourages firms to expand their assortment easier search means that each firm is searched by more consumers because of broader assortments consumers are more likely to find products that better match their ideal preferences improving the efficiency of the market in fact we demonstrate that the market expansion effect can even dominate the competition intensifying effect potentially leading to higher prices broader assortments more profits and expanded welfare
