How much does agricultural composition contribute to cross-country productivity differences?

Since the benchmark model explains 90.2% (6.36/7.05) of the relative productivity differences observed in the data and the counterfactual model explains 62.7% (4.42/7.05), we conclude that agricultural composition accounts for 27.5% of cross-country differences in relative productivity. ...

Do differences in agricultural composition explain labor productivity differences?

We show that differences in agricultural composition across countries explain a substantial part of these labor productivity differences. To this end, we group agricultural products into two sectors: capital-intensive and labor-intensive agriculture. ...

Does the sectoral composition of agriculture depend on the term p n k?

These equations show that the sectoral composition of agriculture depends on the term P n, t / P k, t 1 − ɛ. If this term decreases, then the value of production, capital and land shift towards the capital-intensive agricultural sector and the fraction of farmers in capital-intensive agriculture increases. ...

How do you calculate aggregate production of agricultural goods?

Therefore, the following equation is satisfied: (17) K t = K n, t + K k, t + K m, t. Next, using (10), in Appendix B we obtain that the aggregate production of agricultural goods in each sector is (18) Y s, t = A s, t N t α s R t α s β s x t β s 1 − τ P s, t A s, t β s + α s 1 1 − β s − α s Δ s, t. ...

What is livestock consumption?

The vast majority (94%) of livestock consumption is for food use (meat, dairy products, eggs), and the remainder for non-food products (mainly products from wool, hides and skins). There are large regional variations in the extents, composition and per capita livestock cropland footprints ( Table 5, Fig. 5 ). Table 5. ...

How to optimize energy use in crop production system?

The analysis of energy use in crop production can use to develop a robust computer program for computing various measures of energy use efficiency and develop a computer support program of crop cultivation system to perform and optimize energy use of crop production system. This work was supported by Universiti Putra Malaysia. ...
