"Although all economic activities take place in sectors, economists often devote little attention to differences between and characteristics of sectors. This book tries to show that mesoeconomics, the economic exploration of sectors and groups, is a useful instrument of analysis between microeconomics (the analysis of markets) and macroeconomics (the analysis of economies). In order to do so, economists and social scientists from related disciplines and coming from Europe, Australia and Asia, demonstrate that sectors matter for economic development and the formation of societies. The book includes chapters with rigorous economic analysis, outlooks on economic history, and case studies in order to show the relevance of sectoral issues, this broad range of content making it likely the most comprehensive book on mesoeconomics to date"--Back cover

This paper explores both the necessities and the options for an agricultural system in which no animals are killed by reviewing existing literature. It first identifies a causal chain which can be labelled as vegan wave and which might generate a consensus that animals should not be killed for human consumption. By raising issues of nutrient supply, grassland management and beekeeping, the paper shows that vegan-organic agriculture, vegan-conventional agriculture and post-lethal vegetarian agriculture are three options for such a pathway. Yet, many technical and socioeconomic questions still need to be resolved.

Summary
In order to check the potentials of mesoeconomic research, the example of agricultural economics serves as a case in point to look for advances which contributed to progress in general economic science. In the literature of economic history, the pioneer work by J. H. v. Thünen catches the eye, while T. W. Schultz is a classic Agricultural Economist who won the Nobel Prize. A special section is devoted to mathematical progress within Agricultural Economics and the role of agricultural economists in welfare economics. It is concluded that a high added value can be generated through restricting empirical analyses to a particular sector.
