In this article, we examine the role played by heterogeneity in the popular “connections model” of Jackson and Wolinsky (J Econ Theory 71(1):355–365, <CitationRef CitationID="CR5">1996</CitationRef>). We prove that when heterogeneity with respect to the values of resources, or the information decay parameter, depends on the identity...</citationref>

This paper combines the imperfect reliability model of Bala and Goyal [2000b] with the heterogeneous player model of Galeotti et al. [2006]. We compare existence, characterization and efficiency results in the resulting framework with the results in other frameworks allowing for imperfect...

This paper proposes a new single-lane cellular automaton model for traffic flow. The model takes into account normal drivers’ spacing policies and transportation engineering practices to guarantee that microscopic vehicle behavior is more in line with vehicular movement in the real world. As a...

This study, based on Indian banking mergers, examines the impact of mergers on both the stock market wealth creation and operating performance. The study also analyses the performance of the merged banks in relation to a control group based on financial ratios. The results of cumulative abnormal...

In this note we introduce different levels of decay in the Goyal, Galeotti and Kamphorst (GGK) insider-outsider model of network formation. First, we deal with situations where the amount of decay is sufficiently low to avoid superfluous connections in strict Nash networks and we examine the...

The IMF’s development of the code of good practices on transparency in monetary and financial policies and introduction of safeguard assessments has increased the importance of the transparency of the disclosures found in central bank financial statements. This study looks at the disclosure...

This paper examines whether a country’s economic reforms are affected by reforms adopted by other countries. A simple model of economic reforms is developed to motivate the econometric work. Unsurprisingly, the model predicts that reforms are more likely when factors of production are...
