“…The use of a fixed effect Tobit model for panel data is, however, a problem in our case because of the restricted number of periods (See Greene 2006). The simple Tobit results on R&DI with RE or even FE, that are consistent with our results obtained with the RE Heckman model, are available upon request.…”

Standard innovation surveys do not consider incoming spillovers for non-innovative firms. As a consequence, empirical works may overestimate the absorptive capacity effect, particularly among competitors. The Swiss innovation surveys presented here measure the importance of knowledge for both innovating and non-innovating firms. This original feature enables us to show that knowledge from rivals actually deters manufacturing firms from engaging in R&D activities. We therefore provide stronger evidence that the efficiency effect due to intra-industry spillovers is larger than that generally estimated by data from standard surveys. The R&D based absorptive capacity is weaker than expected, and non-innovative firms as well as non-R&D firms heavily rely on their rivals' knowledge to maintain their technological capacities.

“…The majority of US consumers in previous studies preferred the taste of grain beef to grass beef; therefore, the TASTE_INFO coefficient is expected to be negative. Each participant is represented in the data six times, therefore, LIMDEP's panel data random effects linear regression procedure was used to estimate Equation (2) (Greene 2005).…”

“…This involves using a probit model to estimate the a parameters and a truncated normal regression model to estimate the b parameters. Greene (2005) shows that as the tobit log likelihood is simply the sum of the probit and truncated regression log likelihoods, a simple test of the tobit model as a restriction on Cragg's model can be performed using a likelihood ratio test.…”

Consumer demand for forage-or grass-finished beef is rapidly emerging in the US. This research uses data elicited from consumer surveys and experimental auctions to provide insight on product attributes (taste/flavour, credence and nutritional characteristics) and socio-demographic factors that are most important in determining US consumers' preferences and willingness to pay premiums for grass-finished versus grain-finished beef. Information related to beef production processes increased the probability consumers would be willing to pay a premium for grass-fed beef. However, it appears that health-related messages are more important drivers of willingnessto-pay, on average, than the absence of antibiotics and supplemental hormones and traceability. Labelling information regarding grass-fed beef's nutritional content and related production processes is vital for maintaining and growing premium niche markets for grass-fed beef in the US. The relative size of the willingness to pay estimates compared to previous cost estimates suggest that the Australian beef industry may have a comparative advantage for finishing beef on forage and marketing premium grass-fed differentiated beef products in the US market.

“…In this case the selection mechanism is specified as a probability model to account for the latent selection variable. Another generalization is to allow nonlinear specification of the primary equation (see Greene 1992Greene , 2006andTerza 1995, 1998 for examples of the approach). 14 An increase in the entrant-to-bidder ratio error should be positively associated with gaining entry in the spectrum contest.…”

Terms of use: Documents in EconStor may AbstractCompetition policy attempts to address the potential for market failure by encouraging competition in service markets. Often, in wireless communication service markets, national regulatory authorities seek to encourage entry via the spectrum assignment process. Instruments used include the assignment mode (auction or beauty contest), setting aside licenses and providing bidding (price and quantity) credits for potential entrants, and making more licenses (spectrum blocks) available than incumbent firms (excess licenses). The empirical analysis assesses the effectiveness of these policy instruments on encouraging entry. The econometric results show that the probability of entry is enhanced by using auction assignments and excess licenses. Furthermore, quantity, but not price, concessions encourage entry.JEL Classification: D82, L51, L96
