Abstract:
This paper provides cross-country firm-level evidence on productivity spillovers from foreign direct investment (FDI), separately for greenfield FDI and cross-border mergers and acquisitions (M&As). The granularity of bilateral sector-level FDI datasets allows for addressing possible endogeneity issues by applying a two-step approach whereby an exogenous FDI measure is constructed from a gravity-type regression of bilateral FDI flows. When looking at the effects of greenfield investments on firm labour productivity we find: i) positive intra-industry spillover effects for firms located in advanced countries, and ii) positive backward spillover effects for firms located in emerging and developing countries. These spillovers are driven entirely by FDI from advanced countries. The results from cross-border M&As are noisier, with weakly suggestive evidence for positive intra-industry spillovers in advanced countries but negative backward spillovers in emerging markets and developing countries.

2. The tension between exploding AI investment costs and slow productivity growth

Abstract:
This working paper explores the tension between rapidly increasing artificial intelligence investment costs and the slower pace of productivity growth, raising concerns about a potential ‘economic winter’ for AI. AI has shown significant technological progress, particularly with machine learning and generative AI models like ChatGPT. Investment in AI has surged. But there are concerns about whether these investments will yield proportional returns. Training costs for a single frontier AI model are increasing exponentially, , from $1,000 in 2017 to nearly $200 million in 2024, driven by constant returns to scale in AI model training data, compute capacity and model complexity. Costs could reach billions of dollars by 2030, despite a rapid fall in unit costs per computing operation over the same period. Global AI infrastructure costs in hardware could exceed $1 trillion by the mid-2030s. Amortizing these huge fixed costs requires business models that can be rolled out across a very large user market. Estimates about AI’s contribution to productivity growth vary, from a modest 0.5 percent per year to a very optimistic 10 percent per year. Research shows that productivity usually catches up slowly compared to costs. Without significant productivity gains, the current investment cost trajectory is unsustainable. We estimate that 3 percent annual productivity growth across advanced economies would be required to sustain AI model cost extrapolations to 2030. In an optimistic scenario, productivity increases would result in accelerated economic growth.

3. Construction productivity and global inequality

Abstract:
Two well established stylized facts of economic development are a strong correlation between investment and income, and large differences in investment rates across countries. Construction is the largest component of investment. This paper examines the implications of heterogeneity in construction productivity on cross-country income disparity. We estimate the 10:1 spread in construction productivity among 145 countries in 2005 as a factor of 61.7-fold. Based on a general equilibrium model with input–output linkages, we find that the 10:1 spread in income per capita declines by 45 per cent when the construction productivity gap is eliminated. Sectoral characterization of the aggregate effect of a change in construction productivity shows heterogeneous sectoral contributions to income convergence. Electrical equipment, metals, and transport equipment play stronger roles in transforming the effect of a change in construction productivity to the aggregate level in China compared with other countries.

Abstract:
This paper estimates a three-stage structural model of how foreign linkages affect innovation which in turn affects firm productivity. Using harmonized firm-level data from the World Bank Enterprise Surveys, I construct a panel dataset for 47 developing countries spanning 2003 to 2019. I distinguish between four types of foreign linkages (exports, imports, inward foreign direct investment (FDI) and the use of foreign-licensed technology), and two types of innovation (product innovation and process innovation). To mitigate concerns regarding sample selection and endogeneity biases, I employ advanced panel data methods. In the first stage, I find that being an exporter, using foreign inputs, and using foreign-licensed technology makes firms more likely to invest in R&D, relative to other firms. I also find evidence of sample selection bias which is corrected by using a two-step Heckman selection model. In the second stage, I find that while increases in the R&D intensity increase the probability of product innovation, they have no statistically significant effect on the likelihood of process innovation. In the third stage, I find that product or process innovation is associated with increases in firm-level productivity. These results remain robust across alternative measures of innovation and firm productivity.

6. Reigniting labour productivity growth in developing countries: Do structural reforms matter?

Abstract:
While the negative effects of the 2008 global financial crisis on labour productivity are still fresh in people’s minds, the COVID-19 pandemic raises concerns that productivity will continue to decline. To boost labour productivity and regain economic performance, there is an empirical consensus on the role of structural reforms that allows an efficient reallocation of resources such as labour by reducing rigidities in markets. This study analyses the role of certain structural reforms in improving labour productivity in 35 developing countries over the period of 1990–2014. From the local projection method, our results show that structural reforms have a positive impact on productivity growth in the short and medium terms. The results also illustrate that reforms induce an efficient reallocation of resources within but not between sectors. Taking the business cycle into account in estimates shows that structural reforms stimulate labour productivity growth better in periods of low economic growth.

7. Sorting, Matching and Economic Complexity

Abstract:
Assignment models in trade predict that countries with higher productivity levels are assortatively matched to industries that make better use of these higher levels. Here, we assume that the driver of productivity differences is the differential distribution of factors among countries. Utilizing such a structure, we define and estimate the average factor level (AFL) for countries and products using only the information about the production patterns. Interestingly, our estimates coincide with the complexity variables of (Hidalgo and Hausmann, 2009), providing an underlying economic rationale. We show that AFL is highly correlated with country-level characteristics and predictive of future economic growth.

Abstract:
This paper studies nonparametric identification and counterfactual bounds for heterogeneous firms that can be ranked in terms of productivity. Our approach works when quantities and prices are latent rendering standard approaches inapplicable. Instead, we require observation of profits or other optimizing-values such as costs or revenues, and either prices or price proxies of flexibly chosen variables. We extend classical duality results for price-taking firms to a setup with discrete heterogeneity, endogeneity, and limited variation in possibly latent prices. Finally, we show that convergence results for nonparametric estimators may be directly converted to convergence results for production sets.

Abstract:
This paper studies the multidimensional nature of investments in children within a dynamic framework. In particular, we examine the roles of parental time investments, purchased home goods/services inputs, and market-based child care services. We first document strong increases in total investment expenditures by maternal education; yet expenditure shares, which skew heavily towards parental time, vary little with parental schooling. Second, we develop an intergenerational lifecycle model with multiple child investment inputs to study these patterns and the impacts of policies that alter the prices of different inputs. We analytically characterize investment behavior, focusing on the substitutability of different investment inputs and the way parental skills affect the productivity of family-based inputs. Third, we develop an estimation strategy that exploits intratemporal optimality conditions based on relative demand to estimate substitutability between inputs, the relative productivity of different inputs, and the role played by parental education. This approach requires no assumptions about the dynamics of skill investment, preferences, or credit markets. We also account for mismeasured inputs and wages, as well as unobserved heterogeneity in parenting skills. We further show how noisy measures of child achievement (measured several years apart) can also be incorporated in a generalized method of moments approach to additionally identify the dynamics of skill accumulation. Fourth, we use data from the Child Development Supplement of the Panel Study of Income Dynamics to estimate the skill production technology for children ages 12 and younger. Our estimates suggest complementarity between parental time and home goods/services inputs as well as between these family-based inputs and market-based child care, with elasticities of substitution ranging from 0.2 to 0.5. We find no systematic effects of parental education on the relative productivity of parental time and other home inputs. Finally, we use counterfactual simulations to explore the extent and sources of variation in investments across families, as well as investment responses to changes in input prices. We find that variation in prices explains 48% of the overall variance in investment expenditures, and differences in wages explain more than half of the investment expenditure gap between college-educated and non-college-educated parents. We further show that accounting for the degree of input complementarity implied by our estimates has important implications for the responses of individual inputs to any price change and for the responses in total investments and skill accumulation to large (but not small) price changes.

10. Returns to Skill and the Evolution of Skills for Older Men

Abstract:
This paper shows that repeated cross-section data with multiple skill measures (one continuous and repeated) available each period are sufficient to nonparametrically identify the evolution of skill returns and cross-sectional skill distributions. With panel data and the same available measurements, the dynamics of skills can also be identified. Our identification strategy motivates a multi-step nonparametric estimation strategy. We further show that if any continuous repeated measurement is shown to be linear in skills, a much simpler GMM estimator can be used. Using HRS data on men ages 52+ from 1996-2016, we show that one of the available (continuous and repeated) skill measures is linear in skills and implement our GMM estimation approach. Our estimates suggest that the returns to skill were fairly stable from the mid-1990s to the Great Recession, rising thereafter. We document considerable differences in skills and lifecycle skill profiles over ages 52–70 across cohorts, with more recent cohorts possessing lower skills in their mid-50s but experiencing much weaker skill declines with age. We also document skill differences by education and race, which are stable across ages and explain roughly one-third and one-half, respectively, of the corresponding differences in wages. We observe substantial differences in skills for men in their mid-50s choosing to retire at different ages, but no clear evidence of sharp declines in skills surrounding retirement ages. Finally, we show that individual fixed effects account for more than a third of all skill variation at age 60, with considerable persistence in year-to-year skill innovations.
