The potential for information technology penetration in sub-Saharan Africa (SSA) is very high compared to other regions. Unfortunately, productivity levels the area are also deficient. This study investigates importance of influencing effect foreign direct investment (FDI) on total factor (TFP) dynamics. focus 25 countries SSA. Information measured with mobile phone and internet penetration, wh...

Labor productivity (LP) in the United States has gone from being procyclical to acyclical since the mid1980s. Using industry-level data, this paper first shows that total factor productivity (TFP), which is LP net of capital deepening, has also become much less correlated with output as well as inputs over the same period. Moreover, the bulk of the decline in aggregate TFP’s cyclicality is attr...

Improving agricultural total factor productivity is essential to achieving the high-quality and sustainable development of agriculture. As major global producers, G20 countries play an important role in product trade development. such, it well-positioned a positive improving productivity. This paper uses DEA-Malmquist index method measure (TFP) from 2010 2019, analyzes impact on TFP using two-w...

Using 2605 Chinese A-share listed companies in the mining, manufacturing, and energy production supply sectors from 2009 to 2020, we examine relationship between climate policy uncertainty (CPU) firm-level total factor productivity (TFP). The main findings are as follows: First, CPU significantly reduces TFP, with a greater impact on low-productivity firms than high-productivity firms; second, ...

The study analyzed the maize Total Factor Productivity growth using Data Envelopment Analysis (DEA) based on Malmquist Index in Nigerian. Factors that affect maize total factor productivity growth were also identified using Ordinary Least Square (OLS) method. The study used secondary annual data for the period from 19712010 in order to attain the objective. The result revealed that for the fort...

Introduction We examine the relationship between the Cobb-Douglas production function that is frequently used in information technology (IT) productivity studies and the income accounting identity. In doing so we evaluate the impact of this relationship on the question about aggregation from firm-level data to industry-level data when estimating IT productivity, that is, whether industry-level ...

The total factor productivity (TFP) of a multiple-output multiple-input firm can be defined as the ratio of an aggregate output to an aggregate input. With this definition, index numbers that measure changes in TFP can be expressed as the ratio of an output quantity index to an input quantity index. This paper uses the term multiplicatively complete to describe TFP index numbers that are constr...

The objective of the present study is to investigate empirically the existence of convergence clubs in state-level agricultural productivity of the USA. This is pursued using Total Factor Productivity (TFP) data from 48 contiguous states over the period 1960-99 and time series methods which endogenously allocate states to clubs on the basis of the long-run behavior of the respective productivit...

Standard real business cycle models must rely on total factor productivity (TFP) shocks to explain the observed comovement of consumption, investment, and hours worked. This paper shows that a neoclassical model consistent with observed heterogeneity in labor supply and consumption can generate comovement in the absence of TFP shocks. Intertemporal substitution of goods and leisure induces como...

We propose a model that generates an economic expansion following good news about future total factor productivity (TFP) or investmentspecific technical change. The model has three key elements: variable capital utilization, adjustment costs to investment, and preferences that exhibit a weak short-run wealth effect on the labor supply. These preferences nest, as special cases, the two classes o...
