Firm Characteristics and Influence on Government Rule-Making: theory and evidence

An adversarial game is used to model the amount of influence a firm has over a government regulator, and its equilibrium level of regulation, as a function of firm fundamentals. The effective influence of a firm is identified as comprising both intrinsic and exerted components; where the latter involves distorting regulation via a transfer to the regulator. Understanding the source of a firm's high influence is found to be important for -among other things - predicting whether it faces higher or lower regulatory constraint than other firms. Data from the World Business Environment Survey provides strong evidence in support of model hypotheses across a wide range of government agents, countries, and regulatory areas. Of particular relevance to public debate, large firms are found to be more likely to be influential, but also more likely to experience regulatory constraint than smaller firms.Political Economy; Regulation; Influence

Consumers and the Brain Drain: Product Design and the Gains from Emigration

We consider the welfare effects of skilled worker emigration in a context where skilled labor plays a role in product design. We show such emigration can benefit the residents left behind, even when consumers’ tastes exhibit a form of home bias. This is because emigration improves the design of goods designed by skilled emigrants but consumed in the sending country. In contrast to existing models of beneficial brain drain, our results do not require agglomeration economies, education-related externalities, remittances, return migration, or an emigration “lottery”. Instead, they are driven purely by differences in market size that induce skilled emigrants to design better products abroad than at home.brain drain, international labor migration, product quality

The International Migration of Knowledge Workers: When is Brain Drain Beneficial?

We consider the welfare effects of the emigration of workers who produce a public good (knowledge). We distinguish between the knowledge diversion and knowledge creation effects of such emigration, and show that the remaining residents of a country can gain from emigration, even when tastes for knowledge goods exhibit a kind of 'home bias'. In contrast to existing models of beneficial brain drain (BBD), our results do not require agglomeration economies, education-related externalities, remittances, return migration, or an emigration 'lottery'. Instead, they are driven purely by the public nature of knowledge goods, combined with differences in market size that induce greater knowledge creation by emigrants abroad than at home. BBD is even more likely in the presence of weak sending-country intellectual property rights (IPRs), or when source country IPR policy is endogenized.

Compensation for Indirect Expropriation in International Investment Agreements: Implications of National Treatment and Rights to Invest

International investment agreements allow investors to bring compensation claims when their investments are hurt by new regulations. This requirement that host governments compensate for indirect expropriation helps solve post-investment moral hazard problems such as hold-ups, thereby helping to prevent inefficient over-regulation and encouraging foreign investment. However, when the social or environmental harm of a project is uncertain pre-investment, compensation requirements can interact with National Treatment clauses in a manner that reduces host government welfare and makes them less likely to admit investment. A police powers carveout from the definition of compensable expropriation can be Pareto-improving and increase foreign investment.Institute on Global Conflict and Cooperation for financial support

Bidding for Brains: Intellectual Property Rights and the International Migration of Knowledge Workers

We introduce international mobility of knowledge workers into a model of Nash equilibrium IPR policy choice among countries. We show that governments have incentives to use IPRs in a bidding war for global talent, resulting in Nash equilibrium IPRs that can be too high, rather than too low, from a global welfare perspective. These incentives become stronger as developing countries grow in size and wealth, thus allowing them to prevent the 'poaching' of their 'brains' by larger, wealthier markets.

Cross-Hauling of Polluting Factors: Extended Abstract

A two stage game is analyzed in which citizens who own mobile factors of production also vote for domestic environmental policies. It is shown that individuals have an incentive to cross-haul polluting factors across jurisdictions when direct controls are used to regulate emissions, that this cross-hauling can induce a ratcheting up of environmental policy in both jurisdictions, and can occur even when jurisdictions are identical and offer the same direct rates of return on installed capacity. The importance of the order in which capacity export decisions and voting occur are also analyzed, and it is found that factor mobility may induce ratcheting up of environmental policy even in a jurisdiction that acts as a host to all polluting activity

Overexpression of the RieskeFeS protein increasese electron transport rates and biomass yield

In this study, we generated transgenic Arabidopsis (Arabidopsis thaliana) plants overexpressing the Rieske FeS protein (PetC), a component of the cytochrome b6f (cyt b6f) complex. Increasing the levels of this protein resulted in concomitant increases in the levels of cyt f (PetA) and cyt b6 (PetB), core proteins of the cyt b6f complex. Interestingly, an increase in the levels of proteins in both the photosystem I (PSI) and PSII complexes also was seen in the Rieske FeS overexpression plants. Although the mechanisms leading to these changes remain to be identified, the transgenic plants presented here provide novel tools to explore this. Importantly, overexpression of the Rieske FeS protein resulted in substantial and significant impacts on the quantum efficiency of PSI and PSII,electron transport, biomass, and seed yield in Arabidopsis plants. These results demonstrate the potential for manipulating electron transport processes to increase crop productivity

Multigene manipulation of photosynthetic carbon assimilation increases CO2 fixation and biomass yield in tobacco

Over the next 40 years it has been estimated that a 50% increase in the yield of grain crops such as wheat and rice will be required to meet the food and fuel demands of the increasing world population. Transgenic tobacco plants have been generated with altered combinations of sedoheptulose-1,7-bisphosphatase, fructose-1,6-bisphosphate aldolase, and the cyanobacterial putative-inorganic carbon transporter B, ictB, of which have all been identified as targets to improve photosynthesis based on empirical studies. It is shown here that increasing the levels of the three proteins individually significantly increases the rate of photosynthetic carbon assimilation, leaf area, and biomass yield. Furthermore, the daily integrated measurements of photosynthesis showed that mature plants fixed between 12-19% more CO2 than the equivalent wild-type plants. Further enhancement of photosynthesis and yield was observed when sedoheptulose-1,7-bisphosphatase, fructose-1,6-bisphosphate aldolase, and ictB were over-expressed together in the same plant. These results demonstrate the potential for the manipulation of photosynthesis, using multigene-stacking approaches, to increase crop yields

High throughput procedure utilising chlorophyll fluorescence imaging to phenotype dynamic photosynthesis and photoprotection in leaves under controlled gaseous conditions

© 2019 The Author(s). Background: As yields of major crops such as wheat (T. aestivum) have begun to plateau in recent years, there is growing pressure to efficiently phenotype large populations for traits associated with genetic advancement in yield. Photosynthesis encompasses a range of steady state and dynamic traits that are key targets for raising Radiation Use Efficiency (RUE), biomass production and grain yield in crops. Traditional methodologies to assess the full range of responses of photosynthesis, such a leaf gas exchange, are slow and limited to one leaf (or part of a leaf) per instrument. Due to constraints imposed by time, equipment and plant size, photosynthetic data is often collected at one or two phenological stages and in response to limited environmental conditions. Results: Here we describe a high throughput procedure utilising chlorophyll fluorescence imaging to phenotype dynamic photosynthesis and photoprotection in excised leaves under controlled gaseous conditions. When measured throughout the day, no significant differences (P > 0.081) were observed between the responses of excised and intact leaves. Using excised leaves, the response of three cultivars of T. aestivum to a user - defined dynamic lighting regime was examined. Cultivar specific differences were observed for maximum PSII efficiency (F v′/F m′ - P 130 μmol m-2 s-1 photosynthetic photon flux density (PPFD). Conclusions: Here we demonstrate the development of a high-throughput (> 500 samples day-1) method for phenotyping photosynthetic and photo-protective parameters in a dynamic light environment. The technique exploits chlorophyll fluorescence imaging in a specifically designed chamber, enabling controlled gaseous environment around leaf sections. In addition, we have demonstrated that leaf sections do not different from intact plant material even > 3 h after sampling, thus enabling transportation of material of interest from the field to this laboratory based platform. The methodologies described here allow rapid, custom screening of field material for variation in photosynthetic processes
