The idiosyncratic (microscopic) and systemic (macroscopic) components of market structure have been shown to be responsible for the departure of the optimal mean-variance allocation from the heuristic 'equally-weighted' portfolio. In this paper, we exploit clustering techniques derived from...

This paper analyses the world web of mergers and acquisitions (M&As) using a complex network approach. We use data of M&As to build a temporal sequence of binary and weighted-directed networks for the period 1995-2010 and 224 countries (nodes) connected according to their M&As flows (links). We...

The recent crisis has highlighted the crucial role that existing linkages among banks and financial institutions plays in channeling and amplifying shocks hitting the system. The structure and evolution of such web of linkages can be fruitfully characterized using concepts borrowed from the...

We study the relationships between firm financial structure and growth for a large sample of Italian firms observed from 1998 to 2003. We expand upon existing analyses testing whether liquidity constraints affect firm performance by considering among growth determinants also firm debt structure....

This note revisits the role of migrant social networks as determinants of bilateral-migration flows. We do so using a new database that covers about 190 world countries and features more accurate estimates of bilateral flows than those employed so far. Our battery of gravity-model exercises show...

This paper analyses whether the strengthening of intellectual property rights (IPRs) systems affects decisions of cross-border mergers and acquisitions (M&As), and if their influence is different for developed and developing countries, and across industrial sectors. We estimate an extended...

In this paper we contribute to the debate on macro-prudential regulation by assessing which structure of the financial system is more resilient to exogenous shocks, and which conditions, in terms of balance sheet compositions, capital requirements and asset prices, guarantee the higher degree of...

The issue of transportation is of primary importance in our societies. A large share of greenhouse gases is generated by the transport sector, and road casualties are one among the most common causes of death. In the present work, we study commuter choice between alternative transport modes...

This paper investigates the macroeconomic determinants of global bilateral remittances flows. Using data covering 216 World countries over the 2010-2017 period, we employ a gravity-model approach to explore the role payed by dyadic and country-specific covariates in explaining remittances....
