We study the strategic behavior of two countries facing transboundary CO2 pollution under a differential game setting. In our model, the reduction of CO2 concentration occurs through the carbon capture and storage process, rather than through the adoption of cleaner technologies. Furthermore, we first provide the explicit short-run dynamics for this dynamic game with symmetric open-loop and a special Markovian Nash strategy. Then, we compare these strategies at the games’ steady states and along some balanced growth paths. Our results show that if the initial level of CO2 is relatively high, state dependent emissions reductions can lead to higher overall environmental quality, hence, feedback strategy leads to less social waste.

Deregulation shock in product market and unemployment

In a dynamic general equilibrium model with endogenous markups and labor market frictions, we investigate the effects of increased product market competition. Unlike most macroeconomic models of search, we endogenize the labor supply along the extensive margin. We find numerically that a model with endogenous labor force participation decision produces a decline in the unemployment rate which is almost three times larger than that in a model with fixed labor force. For a calibration capturing alternatively the European and the US labor markets, a deregulation episode, which lowers the markup by 3 percentage points, results in a fall in the unemployment rate by 0.17 and 0.05 percentage point, respectively, while the labor share is almost unaffected in the long-run. The sensitivity analysis reveals that product market deregulation is more effective in countries where product and labor market regulations are high, unemployment benefits are small and labor force is more responsive.

EXPLORING THE LINK BETWEEN LOCAL AND GLOBAL KNOWLEDGE SPILLOVERS: Evidence from Plant-Level Data

We investigate the existence of local (i.e. within-country) and global (i.e. between-country) knowledge spillovers within a single analytical framework. Our analysis is based on an exhaustive database on Irish manufacturing plants covering the period 1986-1994 and focuses on the impact of R\&D spillovers on productivity. Our results show that while the R\&D undertaken by multinationals active in Ireland has had no significant impact on local plants’ productivity, these multinationals have, nevertheless, through their presence, favoured the diffusion of global R\&D spillovers. We furthermore show that while domestic plants benefited from R\&D spillovers emanating from other domestic firms, these spillovers had a much more limited spatial scope compared to multinational-presence induced spillovers. Foreign affiliates in turn, have directly gained from the size of the R\&D stock in their origin country, but there is no evidence that foreign affiliates located in Ireland had benefited from local R\&D spillovers.
