High-value payment systems (HVPSs) are typically liquidity-intensive because the payment requests are indivisible and settled on a gross basis. Finding the right order in which payments should be processed to maximize the liquidity efficiency of these systems is an NP-hard combinatorial...

We consider a long-term contractual relationship in which a buyer procures a fixed quantity of a product from a supplier and then sells it on the market. The production cost is private information and evolves randomly over time. The solution to this dynamic principal-agent problem involves a...

The study analyzed the growth of agricultural activity in the Amazon region and the consequent increase in deforestation. In addition, it was investigated whether the difference in land productivity observed in agriculture in the region of the Legal Amazon can be justified by low efficiency and,...

This paper introduces the latest addition to the modelling toolkit of the Central Bank of Malta: a static Computable General Equilibrium model for Malta named MaCGE-MOD. Developed through a collaboration with the University of Macerata, the model is a multiinput, multi-output and multi-sector...

The computational time required to solve and estimate dynamic economic models is one of the main constraints in empirical research. The Endogenous Grid Method (EGM) proposed by Carroll (2006) is known to offer impressive speed gains over more traditional stochastic dynamic programming methods,...

This study investigates whether agricultural policy reforms could help cushion the impacts of climate change on agriculture by facilitating the relocation of production and international trade. The agricultural sector faces immense challenges in ensuring the provision of food, farm incomes,...

Long-term throughput, as a key performance indicator of a stochastic flow line, is affected by numerous parameters describing the features of the flow line, such as processing time and buffer size. Fast and accurate evaluation methods for a given set of values for those parameters are a...

International grain prices experienced a sharp increase during the 2020/2021 marketing season, most likely due to the unprecedented increase of imported grains by China. What would be the possible impact on international grain markets if China remains a strong grain importer? The scenario...
