This paper deals with a system where batch arrivals wait in a station until a server (a train) is available, at which moment it services all customers in waiting. This is an example of a bulk server, which has many applications in public transportation, telecommunications, computer resource...

This article establishes the Poisson optional stopping times (POST) method by [22] as a near-universal method for solving liquidity-constrained American options, or, equivalently, penalised optimal-stopping problems. In this setup, the decision maker is permitted to "stop", i.e. exercise the...

This paper explores the relationship between disclosing corporate targets and value creation. Our empirical results show the value relevance of voluntarily disclosing a low number of targets, whereas there is a clear additional positive effect of disclosing exactly one corporate target in the...

This article presents an agent-based modelof Prato, an Italian textile district where thousands ofsma1l firms specialise into tiny phases of the whole production process. It is an empirical model atscale 1: 1 that reconstructs the information flows between economic actors and connects them...

This paper investigates how social interactions impact the decision to participate in one’s local environment. Existing work often reports correlations between social interactions and local participation, but it is unclear what the causal direction of this relationship is. A key contribution...

This paper presents a framework for analysing spatial aspects of environmentalpolicies in the regulation of trans-boundary externalities. A spatial priceequilibrium model for two regions is constructed, where interactions betweenthese regions can occur via trade and transport, via mutual...

The purpose of this paper is to build consistent, integrated datasets to investigate whether various disaggregated data can shed light on the possible sources of the statistical discrepancy. Our strategy is first to use disaggregated data to estimate consistent sets of input-output models that...

We investigate which countries have the highest potential to achieve entrepreneurial progress. This progress is defined using an entrepreneurial ladder with five successive steps: “never thought about starting a business”, “thinking about starting a business”, “taking steps to start a...

We test a new model where the entrepreneurial decision is described as a process of successive engagement levels, i.e., as an entrepreneurial ladder. Five levels are distinguished using nearly 12,000 observations from the 2004 “Flash Eurobarometer survey on Entrepreneurship” covering the 25...
