This paper introduces a framework for studying the optimal dynamic allocation of foreign aid among multiple recipients. We pose the problem as one of weighted global welfare maximization. A donor in the North chooses an optimal path for international transfers, anticipating that consumption and...

This paper brings the aid effectiveness debate to the sub-national level. We hypothesize the non-robust results regarding the effects of aid on development in the previous literature to arise due to the effects of aid being insufficiently large to measurably affect aggregate outcomes. Using...

Two issues related to mapping a multi-sector model into a reduced-form value-added model are often neglected: the composition of intermediate goods, and the distinction between the productivity indices for value added and for gross output. We illustrate their significance for growth accounting...

Standard growth accounting exercises find large cross-country differences in aggregate TFP. Here we ask whether specific sectors are driving these differences, and, if this is the case, which these problem sectors are. We argue that to answer these questions we need to consider four sectors. In...

This Paper highlights a problem in using the first-differenced GMM panel data estimator to estimate cross-country growth regressions. When the time series are persistent, the first-differenced GMM estimator can be poorly behaved, since lagged levels of the series provide only weak instruments...

In this paper we quantify the effects of the Small Scale Reservation Laws in India on the aggregate productivity, aggregate output and welfare of the Indian economy. To this end, we extend the span-of-control model by Lucas (1978) into a multi-sector setting and embed it into the neo-classical...

It has been argued that concave models exhibit less ‘endogeneity of growth’ than models with increasing returns to scale. Here we study a simple model of factor saving technological improvement in a concave framework. Capital can be used either to reproduce itself, or, at some additional...

We develop a multi-sector general equilibrium model in which productivity growth is driven by the generation of knowledge. In the model, firms allocate resources towards the production of goods and the production of new knowledge, in response to industry-specific factors of demand and...

Many applications in economics use multi-sector versions of the growth model with Cobb--Douglas production functions at the sector level. In this paper, we measure the U.S. income shares of capital and labour for five sectors that encompass the typical sectors used in the literature. We also...

Pooled regressions, first of eight and then of sixteen countries, show a steady and robust process of endogenous growth in Europe since 1870, interrupted only by the events of World War II and the impact of convergence towards US levels of performance in the 1950s and the 1960s. This result...
