A stochastic model for pure-jump diffusion (the compound renewal process) can be used as a zero-order approximation and as a phenomenological description of tick-by-tick price fluctuations. This leads to an exact and explicit general formula for the martingale price of a European call option. A...

The age at which children leave the parental home differs considerably across countries. We present a theoretical model predicting that higher job security of parents and lower job security of children may delay emancipation. We then provide aggregate evidence which supports this hypothesis for...

Pennings (2000) has shown that the government can speed-up investment by subsidizing the potential investing firm's entry cost while taxing the future proceeds from the investment, so as to render the net expected value of its subsidy program zero. This note argues that while speeding-up the...

Ashtamudi estuary of south India provides many direct and indirect use values to the local community in terms of fishing, coconut husk retting, recreation and inland navigation. Nowadays the estuary is facing many threats like pollution, reclamation, injudicious fishing practices etc. At the...

Notwithstanding the ambiguous research and productivity promoting effects of plant variety protections (PVPs), even in developed countries, many developing countries have adopted PVPs in the past few years, in part to comply with their Trade-Related Aspects of Intellectual Property Rights...

We analyze how the deep current scientific uncertainty regarding future climate conditions affects the design of Public Private Partnerships (PPPs) contracts between a government (principal) and a firm (agent), especially in infrastructure sectors that are highly sensitive to such changing...

This paper starts by unveiling a strong empirical regularity: multinational corporations exhibit higher stock market returns and earning yields than non-multinational firms. Within non-multinationals, exporters exhibit higher earning yields and returns than firms selling only in their domestic...

This paper determines the structural shocks that shape a firm's first year by estimating a structural model of firm growth, learning, and survival using monthly sales histories from 305 Texas bars. We find that heterogeneity in firms' pre-entry scale decisions accounts for about 40% of their...

Though a lot of work has been done on the distribution of job tenures, we are still uncertain about its main determinants.In this paper, we stress random shocks to match productivity after the start of an employment relation.The specificity of investment makes hiring and separation decisions...
