Technological unemployment

This work investigates the relationship between unemployment and technological progress. We analyze briefly the historical context in which the problem of unemployment begins: the emergence of a new economic system, the capitalism. In our research we consider the contributions of two different economists: John Stuart Mill and Karl Marx. They offer two different perspectives to this subject. We also consider the contribution David Ricardo, the first author that realized the conflictive relationship between technical progress and the interest of the workers. We also include an analysis of the problem by using different data collected from Global Wage Report, that is annually offered by the International Labor Organization (ILO). Finally, we also analyze the phenomenon called planned obsolescence. The idea of producing goods with low quality in order to guarantee a future demand (replacing the obsolete goods) has been considered a good option to avoid unemployment. This work ends with some final comments and open questions.

Asymmetric conservation benefits of circle hooks in multispecies billfish recreational fisheries: a synthesis of hook performance and analysis of blue marlin (Makaira nigricans) postrelease survival

We evaluated the conservation benefits of the use of circle hooks compared with standard J hooks in the recreational fishery for Atlantic istiophorid billfishes, noting hooking location and the presence of trauma (bleeding) for 123 blue marlin (Makaira nigricans), 272 white marlin (Kajikia albida), and 132 sailfish (Istiophorus platypterus) caught on natural baits rigged with one of the two hook types. In addition, we used pop-up satellite archival tags (PSATs) to follow the fate of 61 blue marlin caught on natural baits rigged with circle hooks or on a combination of artificial lure and natural bait rigged with J hooks. The frequencies of internal hooking locations and bleeding were significantly lower with circle hooks than with J hooks for each of the three species and were significantly reduced for blue marlin caught on J hooks than for white marlin and sailfish taken on the same hook type. Analysis of the data received from 59 PSATs (two tags released prematurely) indicated no mortalities among the 29 blue marlin caught on circle hooks and two mortalities among the 30 blue marlin caught on J hooks (6.7%). Collectively, the hook location and PSAT data revealed that blue marlin, like white marlin and sailfish, derive substantial conservation benefits from the use of circle hooks, and the negative impacts of J hooks are significantly reduced for blue marlin relative to the other two species.

Liberalização Comercial: Um modelo de Equilíbrio Geral Computável para o Comércio entre Brasil e China

Este estudo avalia o impacto da liberalização comercial entre Brasil e China sobre o comércio, produção, preços, investimento, poupança e emprego. O objetivo da análise é identificar a existência de uma oportunidade de comércio para o Brasil que viabilize um maior crescimento, incremente as exportações brasileiras e reduza o desemprego. A hipótese principal é a existência de ganhos de bem estar no comércio com a China. O modelo utilizado é o GLOBAL TRADE ANALYSIS PROJECT (GTAP) com 10 regiões, 10 produtos, 5 fatores, com retornos constantes de escala e competição perfeita nas atividades de produção. Destacam-se na análise os produtos agropecuários. Utilizam-se três fechamentos macroeconômicos (closure) para avaliar separadamente alguns agregados: a configuração padrão dos modelos CGE (preço da poupança endógeno e pleno emprego); preço da poupança exógeno; e desemprego. Conclui-se que pode haver benefícios para os dois países com o acordo.
