Seminario 16/09: – Berta Ferrer (U. Lleida)- How and how much do air travellers spend? Bringing trip budget share and trip total expenditure together

air-travel

Microeconometric analysis of tourist expenditure as a function of traveler characteristics has focused on total absolute expenditure, on absolute expenditures per trip budget parts, and in relative terms per trip budget parts. The analysis of absolute trip expenditure by budget parts confounds how much (budget volume) and how (budget allocation) tourists spend, while that of…

Seminario 16/07: – Alejandro Cuñat (U. Viena)- Offshoring and Skill-upgrading in French Manufacturing: A Heckscher-Ohlin-Melitz View

imagesNABQN4G5

Abstract: We present a factor-proportions trade model in which heterogeneous firms can offshore intermediate inputs subject to fixed offshoring costs. In the skill-abundant country, high-productivity firms offshore a larger range of labor-intensive inputs to the labor-abundant countries than low-productivity firms. Differently from the traditional versions of factor-proportions trade theory, Heckscher-Ohlin forces operate at the within-industry…

Seminario 16/05: -Asier Mariscal (U. Alicante) – How Firms Accumulate Inputs: Evidence from Import Switching

imports2

Abstract: We uncover new dynamic patterns related to importers age and the macroeconomic environment that static models cannot explain. Our patterns are related to import switching, i.e., the simultaneous adding and dropping of intermediates at the firm level. Three facts stand out. First, switching is pervasive as 65% of firms do it and, at the…

Seminario 16/03: – Manuel García-Santana (U. Pompeu Fabra) – Growing like Spain: 1995-2007

growth

Abstract Spanish GDP grew at an average rate of 3.5% per year during the expansion of 1995- 2007, above the EU average of 2.2%. However, this growth was based on factor accumulation rather than productivity gains. In particular, TFP fell at an annual rate of 0.7%, while it increased at 0.4% in the EU and…

Techno-economic implications of the mass-market uptake of mobile data services: Requirements for next generation mobile networks

ABSTRACT The growth of the mobile data services market is no longer dependent on push strategies from suppliers. On the contrary, demand is now driving the market to the extent that it will not be easy for mobile operating companies to cope up with the demand to come in the near future. Operators are forced…

4 Diciembre: Seminario 2015/28 – J.A. García-Martínez (U. Miguel Hernández) – A theory of media self-silence

shutterstock_116101690

Abstract This paper proposes a theory of media silence. The argument is that news organizations have the power to raise public concern and so affect the probability that there is ex-post verification of the true state of the world. Following the seminal article by Gentzkow and Shapiro (2006), we consider a newspaper that seeks to…

30 Octubre: Seminario 2015/22 – M. I. González-Martínez (U. Murcia) – Nonconstant reputation effect in a dynamic tourism demand model for Spain

spain_tourism

Abstract Following the ideas of the Tourism Area Life Cycle (TALC) theory, we propose a dynamic econometric model for tourism demand where the reputation effect (the effect of the lagged demand on the current tourism demand) is not constant, but dependent on congestion. We test the model using panel data from Spanish regions during the…

23 Octubre: Seminario 2015/21 – M. Solaz (U. Valencia) – Especialización productiva y comercial y generación de valor añadido en la economía española

Seminario 15/20: T. Kehoe (U. Minnesota) y P. Pujolas (U. McMaster)– The Measured Productivity Puzzle: Are Exporters More Productive than Non-Exporters?

Productivity signpost

Abstract Recent research in international trade simultaneously has developed along two branches. Empirical research measures plants’ productivity and shows that exporters are more productive than non-exporters. Theoretical research develops models of heterogeneous firms and shows that exporters are more efficient than non-exporters. We argue that there is a disconnect: the measure of firm productivity used…

Seminario 15/16: M. Solaz (U. Valencia) –International Relocation of Production and Economic Growth

TRADE

Abstract According to the product life-cycle theory, new products are invented and developed in the advanced economies, from which they are initially exported. At a later stage, part or all of their production process moves to lower-wage countries. These dynamics lead to a continuous process of international relocation of production. In this paper, we use…
