Improving technologies create a “buy or wait?” dilemma. In this paper, we consider repeat purchases when the consumer faces an infinite stream of new technologies. We develop a probabilistic model and focus on the role of “more variability” on the process of technological innovation. Similar to real options models, we find that variability in the technological process increases value for the co...

This paper is primarily concerned with the impacts of population aging upon education and skill premium. To study population aging, we utilize an overlappinggeneration model where survival into the old stage is uncertain and population aging is modelled via a higher survival rate. Featuring the household, education and production sectors, our model is analysed under both autarky and two-country...

In this note, a wide range of innovation indicators are analysed in order to describe the innovation behaviour of manufacturing firms in LAC using the recently released Enterprise Surveys 2010. The Enterprise Surveys define innovation rates as the share of firms introducing product and process innovations. The survey also measures the proportion of firms investing in research and development (R...

Crown gall disease caused by Agrobacterium tumefaciens is considered as the main bacterial disease of stone fruit rootstocks in Tunisia against which only prophylactic control measures are available. Therefore, twelve rhizobacterial strains and two reference antagonists Agrobacterium rhizogenes K84 and K1026 were investigated for their efficacy against the causal agent of the disease in vitro, ...

The present note includes explanatory comments about the synergic interaction within the sphere of the socioeconomic analysis between the two following theoretical frameworks: 1. The Darwinian evolutionary model. 2. The computer simulation in accordance with the principia established by Bruno de Finetti and Herbert Simon. J.E.L. Classification: O33, C63, B52

This paper evaluates the impact of global external rebalancing on Developing Asia and the rest of the world using a multi-country multi-sector quantitative model of production and trade. Developing Asia countries currently running a trade surplus (such as People’s Republic of China or Malaysia) see a substantial rise in relative wages and an appreciation in the real exchange rate. They also see...

Much has been written on the determinants of input and technology adoption in agriculture, with issues such as input availability, knowledge and education, risk preferences, profitability, and credit constraints receiving much attention. This paper focuses on a factor that has been less well documented: the differential ability of households to take on risky production technologies for fear of ...

In this note, a wide range of innovation indicators are analyzed in order to describe the innovation behavior of manufacturing firms in the Latin American and Caribbean (LAC) region using the recently released Enterprise Surveys 2010. The Enterprise Surveys define innovation rates as the share of firms introducing product and process innovations. The survey also measures the proportion of firms...

This paper extends Symeonidis (2003)’s duopoly model with product differentiation to discusses how FDI spillovers that decreases the quality difference between vertically differentiated products of the home and foreign firms affects the home firm’s decision on plant location. This paper shows that whether the degree of spillover is exogenous or endogenous, it may have a positive relationship wi...
