Abstract
In a multi-sector and multi-region framework, this paper employs a dynamic general equilibrium model to analyze climate-resilient economic development (DGE-CRED) in Vietnam. We calibrate sector and region-specific damage functions and quantify climate variable impacts on productivity and capital formation for various shared socioeconomic pathways (SSPs 119, 245, and 585). Our results based on simulations and cost-benefit analyses reveal a projected 5 percent reduction in annual GDP by 2050 in the SSP 245 scenario. Adaptation measures for the dyke system are crucial to mitigate the consumption gap, but they alone cannot sufficiently address it. Climate-induced damages to agriculture and labor productivity are the primary drivers of consumption reductions, underscoring the need for focused adaptation measures in the agricultural sector and strategies to reduce labor intensity as vital policy considerations for Vietnam’s response to climate change.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
Journal of Comparative Economics,
Nr. 3,
2022
Abstract
East German manufacturers’ revenue productivity is substantially below West German levels, even three decades after German unification. Using firm-product-level data with product quantities and prices, we analyze the role of product specialization and show that the prominent “extended work bench hypothesis” cannot explain these sustained productivity differences. Eastern firms specialize in simpler product varieties generating less consumer value and being manufactured with less or cheaper inputs. Yet, such specialization cannot explain the productivity gap because Eastern firms are physically less productive for given product prices. Hence, there is a genuine price-adjusted physical productivity disadvantage of Eastern compared to Western firms.

Do Firms Respond to Gender Pay Gap Transparency?
Morten Bennedsen, Elena Simintzi, Margarita Tsoutsoura, Daniel Wolfenzon
Journal of Finance,
Nr. 4,
2022
Abstract
We examine the effect of pay transparency on the gender pay gap and firm outcomes. Using a 2006 legislation change in Denmark that requires firms to provide gender-disaggregated wage statistics, detailed employee-employer administrative data, and difference-in-differences and difference-in-discontinuities designs, we find that the law reduces the gender pay gap, primarily by slowing wage growth for male employees. The gender pay gap declines by 2 percentage points, or 13% relative to the prelegislation mean. Despite the reduction of the overall wage bill, the wage transparency mandate does not affect firm profitability, likely because of the offsetting effect of reduced firm productivity.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
Abstract
East German manufacturers’ revenue productivity (value-added per worker) is some 8 (25) percent below West German levels, even three decades after German unification. Using firm-product-level data containing information on product quantities and prices, we analyse the role of product specialisation and reject the prominent ‚extended work bench hypothesis‘, stating a specialisation of Eastern firms in the intermediate input production as explanation for these sustained productivity differences. We decompose the East’s revenue productivity disadvantage into Eastern firms selling at lower prices and producing more physical output for given amounts of inputs within ten-digit product industries. This suggests that Eastern firms specialise vertically in simpler product varieties generating less consumer value but being manufactured with less or cheaper inputs. Vertical specialisation, however, does not explain the productivity gap as Eastern firms are physically less productive for given product prices, implying a genuine physical productivity disadvantage of Eastern compared to Western firms

Immigration and the Rise of American Ingenuity

American Economic Review,
Nr. 5,
2017
Abstract
We build on the analysis in Akcigit, Grigsby, and Nicholas (2017) by using US patent and census data to examine the relationship between immigration and innovation. We construct a measure of foreign born expertise and show that technology areas where immigrant inventors were prevalent between 1880 and 1940 experienced more patenting and citations between 1940 and 2000. The contribution of immigrant inventors to US innovation was substantial. We also show that immigrant inventors were more productive than native born inventors; however, they received significantly lower levels of labor income. The immigrant inventor wage-gap cannot be explained by differentials in productivity.
