This paper offers an empirical analysis of harvest functions for the two main Chilean pelagic fisheries, which are characterized by cyclical fish abundance. Two main results are obtained. First, we identify production-side effects that weaken the incentives to adjust towards lower fishing...

This paper examines estimations of technical catch efficiency for a sample of 204 industrial vessels operating at the pelagic grounds of Southern-Central Chile during the 1985-95 period. We consider a Translog stochastic frontier model à-la Battese-Coelli

This paper estimates technical efficiency in fishing activities of industrial vessels that operated during the 1990-2000 period in the "Merluccius gayi" fishery. Two algorithms -with fixed and random effects- used to estimate stochastic production frontiers are compared. The main results are:...

Productive scales of marine fisheries often show rigidities as fish stock falls, which on occasions have generated fishery collapse. In this paper we analyze the two largest fisheries in Chile as to its landings volume, and which concurrently face large fish-stock volatility. We study...

Este trabajo presenta estimaciones de eficiencia técnica en faenas de pesca de barcos industriales que operaron en la década 1990-2000, en la pesquería de merluza común. Se comparan los resultados de dos algoritmos que estiman modelos de fronteras estocásticas de producción, uno con...

This note deals with a harvesting model for a single stock fishery. In the case of small pelagic fish it seems reasonable to consider harvest functions depending nonlinearly on fishing effort and on fish stock. Empirical evidence about these fish species suggests that marginal catch does not...

This paper applies a pairwise approach to investigate the validity of the law of one price in the crude oil markets. Price differentials appear smaller between crude oil pairs with similar physical/chemical characteristics and also for pairs within OPEC.

We adopt time-series and cross-section methods to analyse long-term relationships between pairs of crude oil prices and assess how physical and institutional factors affect their speed of reaction to exogenous shocks. Using a methodological approach which does not require identifying specific...

This study examines the determinants of blue economy activities, namely tourism and fisheries, in 21 Asia and Pacific island countries during the period 1996 to 2016. Using a panel data model, it was found that the size of the blue economy positively depends on the gross fixed capital formation...
