Monopolistic competition: Critical evaluation the theory of monopolistic competition with specific reference to the seminal 1977 paper by Dixit and Stiglitz
No full textThis paper revisits the D-S (Dixit-Stiglitz) model. It’s a simple general monopolistic model with n monopolistic goods, and a numeraire good Labour ( w=1); aggregation for all goods in the economy. We have considered in our paper constant elasticity of substitution case(CES).On the supply side, the assumption is that the labour is perfectly mobile factor of production across the sectors, so as a result in our model there is single wage rate which we denote as in the other sectors than monopolistic there is constant returns to scale and we can specify the production function: The Dixit-Stiglitz model of monopolistic competition works only when n is large; from the functions of the productions best when one applies linear production function. Under increasing returns to scale monopolistic competition will lead to a greater degree of product differentiation than it is socially optimal.Monopolistic competition, CES, Dixit-Stiglitz model, product differentiation
A comment on "An arbitrage-free approach to quasi-option value" by Coggins and Ramezani
No full textIn their article ?An Arbitrage-Free Approach to Quasi-Option Value? [J. Environm. Econom. Management 35, 103-125, 1998], Coggins and Ramezani interpreted the concept of quasi-option value introduced by Arrow and Fisher [Quart. J. Econom. 88, 1974, 312-319] as being identical to Dixit and Pindyck?s real option value. This means their approach differs from the approach by Fisher and Hanemann [J. Environm. Econom. Management 14, 183-190, 1987] who formalized the concept of quasi-option value a decade before. By indirectly characterizing Dixit and Pindyck?s real option value Coggins and Ramezani confirmed classic results in the field of real options theory. --
OPTIMAL EXPORT POLICY IN THE PRESENCE OF R&D INVESTMENT
No full textThe purpose of this paper is to analyze the optimal export policy in a two-stage game in which a domestic and a foreign firm compete in price and R&D investment. Under international Bertrand duopoly, an export subsidy directly promotes excess price competition, as delineated by Eaton and Grossman (1986). But, in the presence of international R&D rivalry, an export subsidy indirectly reduces the rival's R&D level, and thereby raises its cost. This effect offsets the negative effect of the export subsidy resulting in excess price competition. We show that an export subsidy (tax) policy is optimal if the relative return to R&D is great (small), provided that a government can precommit to an ex ante optimal export policy.
Gastronomic Tourism Innovations
No full textThe spectacularization of food consumption and the commercialization of food festivals and fairs are therefore the basis of two new and innovative tasting formats, such as food trucks and temporary restaurants. Both of these concepts bring innovation in terms of gastronomic tourism proposals, by shaping new kinds of food experiences, since the consumption of food becomes itself the central and not a marginal moment in a tourist experience. The findings coming from this content analysis are in line with the current literature about the main features in gastronomic tourism and substantially confirm the most discussed assumptions regarding issues in food experiences. Food consumption is an essential element of each kind of tourism experience and it has also been recognized as a component of regional identity and culture and the linkages between food and tourism is a merger which engages tourists to seek out authentic, novel, and local food experiences related to the places they are visiting

When to Get In and Out of Dairy Farming: A Real Option Analysis
No full textThe Dixit entry/exit real option model was applied to the entry/exit decisions of New York dairy farmers. For the cost structure of a 500-cow farm the entry milk price is 10.84. For the 50-cow farm cost structure the entry price is higher at 13.48. If infinite numbers of representative farms enter and exit at these prices, the price of milk should range between 17.52 per cwt.Dairy farming, entry-exit, investment, real options, Farm Management,
Abstract BS1-1: Transcription factor stability and stem cell maintenance
No full textAbstract
Proto-oncogenes ETV1, ETV4, and ETV5 belong to the PEA3 family of ETS transcription factors and have been identified recently in prostate cancer chromosomal rearrangements that result in their overexpression. Little is known, however, about their post-translational regulation. We previously showed that ETV1, ETV4, and ETV5 interact with the ubiquitin ligase COP1. COP1 together with its binding partner DET1 ubiquitinates ETV1, resulting in its proteasomal degradation. Importantly, truncation of ETV1 by the TMPRSS2:ETV1 translocation found in prostate cancer removes its COP1 binding motif and thereby enhances its stability. Consistent with a critical role for COP1 in regulating PEA3 transcription factors, COP1 deficiency in primary mouse prostate cells produced prostate intraepithelial neoplasia in vivo. The relationship between COP1 and ETV1 was also evident in human prostate cancer samples where loss of COP1 expression correlated with elevated ETV1 protein. I will discuss unpublished work that underscores the importance of COP1 as tumor suppressor.

ICT as Technical Change in the Matching and Production Functions of a Pissarides-Dixit-Stiglitz model
No full textIn this paper we integrate two workhorse models in economics: Themonopolistic competition model of Dixit and Stiglitz and the search unemploymentmodel of Pissarides. Information and communication technology (ICT) is interpretedas i) technical progress in the matching function of the Pissarides labour marketsearch model where it is increasing the probability of filling a vacancy, and ii) astechnical change in the production function of the Dixit-Stiglitz goods market modelwhere it is increasing fixed costs and decreasing variable costs. All effects together,modelled as a permanent once-and-for-all ICT and Internet shock, increase thevacancy/ unemployment ratio, decrease the long-run equilibrium unemployment rate,and increase wages.
