due to the importance of the import management, this study applies generalized ardl approach to estimate midas regression for wheat import value and to compare the accuracy of forecasts with those competed by the regression with adjusted data model. mixed frequency sampling models aim to extract information with high frequency indicators so that independent variables with lower frequencies are ...

Utilising wildlife as natural resources has a long history and wide appeal for many nations, while seeking international that is sustainably managed the primary responsibility of Convention on International Trade in Endangered Species Wild Fauna Flora (CITES). However, data-driven trade reviews are required, utilising CITES data to increase our understanding facilitate evidence-based conservati...

We propose a model that simulates climate change impacts on crop production and food prices under partial equilibrium. Our incorporates system of Laspeyres price quantity indices link structurally estimated community-level produce supply functions to market level demand functions. The estimation accounts for corner solutions associated with disaggregate land use observations is constrained repr...

We compare emissions taxes and quotas when a (strategic) regulator and (non-strategic) firms have asymmetric information about abatement costs, and all agents use Markov perfect decision rules. Firms make investment decisions that affect their future abatement costs. For general functional forms, firms’ investment policy is information-constrained efficient when the regulator uses a quota, but ...

Gender, Competition and the Efficiency of Policy Interventions Recent research has shown that women shy away from competition more often than men. We evaluate experimentally three alternative policy interventions to promote women in competitions: Quotas, Preferential Treatment, and Repetition of the Competition unless a critical number of female winners is reached. We find that Quotas and Prefe...

Some properties of the set of many-to-one stable matchings for firms that have responsive preferences and quotas are not necessarily true when firms' preferences are substitutable. In particular, we provide examples in which firms have substitutable preferences but firms and workers may be ``single'' in one stable matching and matched in another one. We identify a set of axioms on firms' prefer...

Building on the political economy literature, we develop a conceptual model and apply it to explain the OPEC pricing behavior. We model OPEC as a cartel-of-nations where politician use two instruments: production quotas and domestic fuel consumption subsidies. Our model explains the wedge between domestic fuel prices in OPEC countries and in the rest of the world. The empirical estimates show t...

This paper studies the effects of quota-based labor regulations on firms in the context of Saudi Arabia’s Nitaqat program, which imposed quotas for Saudi hiring at private firms. I use a comprehensive firm-level administrative dataset and exploit kinks in hiring incentives generated by the quotas to estimate the effects of this policy. I find that the program increased native employment at subs...
