This note shows that protection induced export promotion can arise even in the absence of economies of scale , which have been long analysed as factors sliding an import substituting industry up the scale of comparative advantage and turning it into an exporter eventually. Even with an upward-sloping marginal-cost curve, a domestic monopolist can be protected and could then charge discriminatory prices in domestic and export markets, thus becoming an exporter whereas; free trade would have destroyed the monopoly and led to imports instead.

AbstractAs China ramped-up coal power capacities rapidly while CO2 emissions need to decline, these capacities would turn into stranded assets. To deal with this risk, a promising option is to retrofit these capacities to co-fire with biomass and eventually upgrade to CCS operation (BECCS), but the feasibility is debated with respect to negative impacts on broader sustainability issues. Here we present a data-rich spatially explicit approach to estimate the marginal cost curve for decarbonizing the power sector in China with BECCS. We identify a potential of 222 GW of power capacities in 2836 counties generated by co-firing 0.9 Gt of biomass from the same county, with half being agricultural residues. Our spatially explicit method helps to reduce uncertainty in the economic costs and emissions of BECCS, identify the best opportunities for bioenergy and show the limitations by logistical challenges to achieve carbon neutrality in the power sector with large-scale BECCS in China.

Abstract Markup cyclicality has been central for debating policy effectiveness and understanding business-cycle fluctuations. However, measuring the cyclicality of markups is as important as understanding the microeconomic mechanisms underlying that cyclicality. The latter requires measurement of firm-level markups and separating supply from demand shocks. We construct a novel dataset with detailed (multi-)product-level prices for individual firms. By estimating a structural model of supply and demand, we evaluate how companies adjust prices and marginal costs as a response to shocks. We find that price markups respond positively to supply shocks and negatively to demand shocks. The mechanism explaining the observed markup behaviour is the same for both shocks: incomplete pass-through of changes along the marginal-cost curve to price adjustments. These observed price and output responses are consistent with dynamic demand considerations. Finally, we use our estimated shocks to show how aggregate markup fluctuations in the sample period are mostly explained by aggregate demand shocks.

This study analyses the short-run hydro generation scheduling for the wind power differences from the contracted schedule. The approach for construction of the joint short-run marginal cost curve for the hydro-wind coordinated generation is proposed and applied on the real example. This joint short-run marginal cost (SRMC) curve is important for its participation in the energy markets and for economic feasibility assessment of such coordination. The approach credibly describes the short-run marginal costs which this coordination bears in “real life”. The approach is based on the duality framework of a convex programming and as a novelty combines the shadow price of risk mitigation capability and the water shadow price. The proposed approach is formulated as a stochastic linear program and tested on the case of the Vinodol hydropower system and the wind farm Vrataruša in Croatia. The result of the case study is a family of 24 joint short-run marginal cost curves.
