In the Dasgupta-Heal-Solow-Stiglitz model of capital accumulation and resource depletion we show the following equivalence: If an efficient path has constant (gross and net of population growth) savings rates, then population growth must be quasi-arithmetic and the path is a maximin or a...

This paper uses the endogenous regime switching model with dynamic feedback and interactions developed by Chang et al. (2023) to estimate global food price mean and volatility indicators, the latter measuring uncertainty and risk in the global food market. Both are then included in structural...

Economic and population growth increasingly pressure the Earth system. Fertile soils are essential to ensure global food security, requiring high-yielding agro-technological regimes to cope with rising soil degradation and macro-nutrients deficiencies, which may be further exacerbated by climate...

To promote biodiversity, a diverse landscape is necessary. Structural change in agriculture and increasing cost pressure have led to the trend of fewer farms and larger farming units with less diversity. Reversing this trend is a societal task that requires a willingness to make sacrifices. For...

This paper summarizes some of the milestones involved in the road leading "from Agronomist to Agricultural Economist". Personal anecdotes are presented, as well as aspects of professional work undertaken. In relation to this, selected results of research work related to the agricultural firm in...

From 1962 to 2013, the People's Republic of China's (PRC's)agricultural employment share declined from 82% to 31%. The transfer of workers out of low-productivity agriculture is a fundamental pillar of the PRC's aspirations to progress and eventually become a high-income economy. We hypothesize...

Among the economic activities in Brazil's Midwest region, agriculture has an important role in the regional economy, with the aim of this study to evaluate the recent situation of regional agriculture in order to identify constraints and opportunities for development and discuss actions that may...

Much of the recent dynamism of the Brazilian agricultural sector occurred in activities developed in Brazil's South, Southeast and Midwest regions. Specifically, the Southeast region was responsible in 2006 for approximately 34% of the value of agricultural production according to data from the...

The Brazilian agricultural market is a key source of government revenues. Therefore, many studies are being done to assess the sector's productivity gain over time. However, the regional analysis of agricultural productivity still is not investigated. This work focuses on mapping the gain of...

Nutrition transition is driven by quantity increase and structural change in food consumption. Particularly, meat consumption plays an important role. This study proposes a simple but innovative method to empirically decompose the total income effect on nutrition improvement into direct income...
