Is "learning-by-exporting" important? : micro-dynamic evidence from Colombia, Mexico and Morocco by Sofronis Clerides( Book )

14 editions published in 1996 in English and held by 77 WorldCat member libraries worldwide

Is there any empirical evidence that firms become more efficient after becoming exporters? Do firms that become exporters generate positive spillovers for domestically-oriented producers? In this paper we analyze the causal links between exporting and productivity using firm-level panel data from three semi-industrialized countries. Representing export market" participation and production costs as jointly dependent autoregressive processes, we look for evidence that firms' stochastic cost processes shift when they break into foreign markets. We find that relatively efficient firms become exporters, but firms' unit costs are not affected by previous export market participation. So the well-known efficiency gap between exporters and non-exporters is due to self-selection of the more efficient firms into the export market, rather than learning by exporting. Further, we find some evidence that exporters reduce the costs of breaking into foreign markets for domestically oriented producers, but they do not appear to help these producers become more efficient
Do R & D subsidies stimulate or displace private R & D? : evidence from Israel by Saul Lach( Book )

18 editions published in 2000 in English and held by 73 WorldCat member libraries worldwide

In evaluating the effect of an R&D subsidy we need to know what the subsidized firm would have spent on R&D had it not received the subsidy. Using data on Israeli manufacturing firms in the 1990s we find evidence suggesting that the R&D subsidies granted by the Ministry of Industry and Trade stimulated long-run company-financed R&D expenditures: their long-run elasticity with respect to R&D subsidies is 0.22. At the means of the data, an extra dollar of R&D subsidies increases long-run company-financed R&D expenditures by 41 cents (total R&D expenditures increase by 1.41 dollars). Although the magnitude of this effect is large enough to justify the existence of the subsidy program, it is lower than expected given the dollar-by-dollar matching upon which most subsidized projects are based. This less than full' effect reflects two forces: first, subsidies are sometimes granted to projects that would have been undertaken even in the absence of the subsidy and, second, firms adjust their portfolio of R&D projects-closing or slowing down non-subsidized projects-after the subsidy is received
Measuring temporary labor outsourcing in U.S. manufacturing by Marcello M Estevo( Book )

18 editions published in 1999 in English and held by 71 WorldCat member libraries worldwide

Several analysts claim that firms have been using more flexible work arrangements in order to contain the costly adjustment of labor to changes in economic conditions. In particular, temporary help supply (THS) employment has increased dramatically in the last ten years. However, there is only scant evidence on the industries that are hiring this type of worker. In particular, some anecdotal evidence points to the fact that manufacturing industries have substantially stepped up their demand for THS workers since the mid-1980s. If this is true, not accounting for this flow of workers from the service sector to manufacturing may lead to misleading conclusions about the cyclical and long-term path of manufacturing employment and hours of work. We close this gap by providing several estimates of the number of individuals employed by temporary help supply (THS) firms who worked in the manufacturing sector from 1972 to 1997. One estimate, in particular, is based on a new methodology that uses minimal assumptions to put bounds on the probability that a manufacturing worker is employed by a THS firm. The bounds rely on readily available data on workers' individual characteristics observable in the CPS. We show that manufacturers have been using THS workers more intensively in the 1990s. In addition, the apparent flatness of manufacturing employment in the 1990s can be explained in part by this type of outsourcing from the service sector. Finally, not accounting for THS hours overstated the increase in average annual manufacturing labor productivity by g percentage point during the 1991-1997 period
Staggering and synchronization in price-setting : evidence from multiproduct firms by Saul Lach( Book )

14 editions published between 1994 and 1996 in English and held by 63 WorldCat member libraries worldwide

Most of the theoretical literature on price-setting behavior deals with the special case in which only a single price is changed. At the retail-store level, at least, where dozens of products are sold by a single price-setter, price-setting policies are not formulated for individual products. This feature of economic behavior raises a host of questions whose answers carry interesting implications. Are price setters staggered in the timing of price changes? Are price changes of different products synchronized within the store? If so, is this a result of aggregate shocks or of the presence of a store- specific component in the cost of adjusting prices? Can observed small changes in prices be rationalized by a menu cost model? We exploit the multiproduct dimension of the dataset on prices used in Lach and Tsiddon (1992a) to explore several of these and other issues. To the best of our knowledge this is the first empirical work on this subject
Outsourcing and technological change by Ann Bartel( Book )

19 editions published between 2005 and 2009 in English and German and held by 58 WorldCat member libraries worldwide

In this paper we argue that an important source of the recent increase in outsourcing is the computer and information technology revolution, characterized by increased rates of technological change. Our model shows that an increase in the pace of technological change increases outsourcing because it allows firms to use services based on leading edge technologies without incurring the sunk costs of adopting these new technologies. In addition, firms using more IT-intensive technologies face lower outsourcing costs of IT-based services generating a positive correlation between the IT level of the user and its outsourcing share of IT-based services. This implication is verified in the data
Incentives and invention in universities by Saul Lach( Book )

21 editions published between 2003 and 2008 in English and held by 57 WorldCat member libraries worldwide

We show that economic incentives affect the number and commercial value of inventions generated in universities. Using panel data for 102 U.S. universities during the period 1991-1999, we find that universities which give higher royalty shares to academic scientists generate more inventions and higher license income, controlling for other factors including university size, quality, research funding and technology licensing inputs. The incentive effects are much larger in private universities than in public ones. For private institutions there is a Laffer curve effect: raising the inventor's royalty share increases the license income retained by the university. The incentive effect appears to work both through the level of effort and sorting of academic scientists
The evolution of the demand for temporary help supply employment in the United States by Marcello M Estevo( Book )

16 editions published in 1999 in English and held by 56 WorldCat member libraries worldwide

The Bureau of Labor Statistics has reported an extraordinary increase in temporary help supply (THS) employment during the late 1980s and the 1990s. However, little is known about the venues where these THS employees actually work. Our estimates indicate that the proportion of THS employees in each major American industry, except the public sector, increased during 1977-97. By 1997, close to 4 percent of the employees in manufacturing and services were THS workers. In the service sector, the increase was accompanied by a large increase in direct hires. In manufacturing, however, it was accompanied by a decline in direct hiring from its peak in 1989 even though output increased substantially in the 1990s. Practically, all of the growth in THS employment is attributed to a change in the hiring behavior of firms, rather than to a disproportional increase in the size of more THS-intensive industries
R & D, investment and industry dynamics by Saul Lach( Book )

8 editions published between 1992 and 1995 in English and held by 56 WorldCat member libraries worldwide

We present a model of industry evolution where the dynamics are driven by a process of endogenous innovations, followed by subsequent embodiments in physical capital. Traditionally, the only distinction between R & D and physical investment was one of labeling: the first process accumulates an intangible stock (knowledge) while the second accumulates physical capital; both stocks affect output in a symmetric fashion. We argue that the story is not that simple, and there is more to it than differences in the object of accumulation. Our model stresses the causal relationship between past R & D expenditures and current investments in machinery and equipment. This causality pattern, which is supported by the data, also explains the observed higher volatility of physical investment (relative to R & D expenditures)
Existence and persistence of price dispersion : an empirical analysis by Saul Lach( Book )

15 editions published between 2000 and 2002 in English and held by 53 WorldCat member libraries worldwide

Using a unique data set on store-level monthly prices of four homogenous products sold in Israel, I study the existence and characteristics of the dispersion of prices across stores, as well as its persistence over time. I find that price dispersion prevails even after controlling for observed and unobserved product heterogeneity. Moreover, intra-distribution mobility is significant: stores move up and down the cross-sectional price distribution. Thus, consumers cannot learn about stores that consistently post low prices. As a consequence, price dispersion does not disappear and persists over time as predicted by Varian's (1980) model of sales
Better late than early : vertical differentiation in the adoption of a new technology by Prajit K Dutta( Book )

10 editions published in 1993 in English and held by 47 WorldCat member libraries worldwide

After the initial breakthrough in the research phase of R&D a new product undergoes a process of change, improvement and adaptation to market conditions. We model the strategic behavior of firms in this development phase of R&D. We emphasize that a key dimension to this competition is the innovations that lead to product differentiation and quality improvement. In a duopoly model with a single adoption choice, we derive endogeneously the level and diversity of product innovations. We demonstrate the existence of equilibria in which one firm enters early with a low quality product while the other continues to develop the technology and eventually markets a high quality good. In such an equilibrium, no monopoly rent is dissipated and the later innovator makes more profits. Incumbent firms may well be the early innovators, contrary to the predictions of the hypothesis
Diffusion lags and aggregate fluctuations by Boyan Jovanovic( Book )

10 editions published in 1993 in English and held by 47 WorldCat member libraries worldwide

This paper studies how random product innovations affect the time series properties of aggregates. It posits that recurring inventions of new intermediate goods differ in quality, and that their usage spreads gradually through the economy. It examines how fluctuations in per capita GNP are affected by these features of the innovation process. Micro data from the U.S. show, first, that the dispersion of products' qualities is quite large: Its coefficient of variation is 0.56. More importantly, they also show that the rate of diffusion of new products is relatively slow; Only 4.3% of the potential market size is realized in every year. Because diffusion is so slow, the model explains only low frequency movements in per capita GNP in the G-7 countries
The diffusion of technology and inequality among nations by Boyan Jovanovic( Book )

8 editions published between 1990 and 1991 in English and held by 34 WorldCat member libraries worldwide

One usually accounts for output growth in terms of the growth of the primary inputs: labor, physical capital, and possibly human capital. In this paper we account for growth with labor and with intermediate goods. Because we have no measures of the extent of adoption of most intermediate goods in most countries, we have to assume something about how they spread, based on what we see in U.S. data. We find that if all countries have (al the same production function, (b) the same speed of adoption technology, and (c) imperfectly correlated technology shocks, then we can easily account for the extent and persistence of inequality among nations. Unfortunately, while it easily generates the sorts of low frequency movements that we observe, our technology shock seems to have little to do with high frequency movements in GNP so that if our definition of this shock is correct, real business cycle models are way off the mark
The interaction between capital investment and R & D in science-based firms by Saul Lach( Book )

5 editions published between 1987 and 1988 in English and held by 20 WorldCat member libraries worldwide

This paper analyzes the interaction among R & D, capital investment, and the stock market rate of return for 191 firms in science-based industries for the period 1973-1981. Using a framework based on dynamic factor analysis, we show how several prominent hypotheses about the determination of R & D and investment generate testable parameter restrictions. The data indicate that R & D Granger-causes investment, but that investment does not Granger-cause R & D. We use this finding to examine the validity of those hypotheses, to characterize the movements over time of R & D and investment, and to measure the stock market valuation of these movements
Asymmetric price effects of competition by Saul Lach( Book )

9 editions published between 2009 and 2015 in English and held by 14 WorldCat member libraries worldwide

In markets where price dispersion is prevalent the relevant question is not what happens to the price when the number of firms changes but, instead, what happens to the whole distribution of equilibrium prices. Using data from the gasoline market in the Netherlands, we find, first, that markets with a given number of competitors have price distributions that first-order stochastically dominate the corresponding price distributions in markets with one more firm. Second, the competitive response varies along the price distribution and is stronger at prices in the medium to upper part of the distribution. Finally, consumer gains from competition depend on how well informed they are and turn out to be larger for relatively attentive consumers. To account for these empirical results, we propose a generalisation of Varian's (1980) well-known model of sales that allows for richer heterogeneity in consumer price information

Using elicited choice probabilities to estimate random utility models : preferences for electricity reliability by Asher Blass( Book )

10 editions published in 2008 in English and held by 12 WorldCat member libraries worldwide

When data on actual choices are not available, researchers studying preferences sometimes pose choice scenarios and ask respondents to state the actions they would choose if they were to face these scenarios. The data on stated choices are then used to estimate random utility models, as if they are data on actual choices. Stated choices may differ from actual ones because researchers typically provide respondents with less information than they would have facing actual choice problems. Elicitation of choice probabilities overcomes this problem by permitting respondents to express uncertainty about their behavior. This paper shows how to use elicited choice probabilities to estimate random utility models with random coefficients and applies the methodology to estimate preferences for electricity reliability in Israel
