We estimate a structural model of herding behavior in which feedback arises due to mutual concerns of traders over the unobservable "true" level of market liquidity. In a herding regime, random shocks are exacerbated by endogenous feedback, producing a dampened power-law in the fluctuation of...

Loan syndication increases bank interconnectedness through co-lending relationships. We study the financial stability implications of such dependency on syndicate partners in the presence of shocks to banks' capital. Model simulations in a network setting show that such shocks can produce rare...

The recent US Real Estate Bubble had consequences not only for the real economy but for the stock market as well. Real Estate Investment Trusts' (REITS) prices reached levels which could not be supported by their fundamentals until mid-2007. Using this observation as a starting point we examine...

Severe cash constraints faced by the Greek Government due to a pretty demanding schedule of interest and amortization payments in the remainder of 2015 have lately engineered a new explosion of sovereign bond spreads and rekindled fears of a GRexit down the road. Such fears have been exacerbated...

Price limits are automated mechanisms that pre-specify the maximum daily percentage range - upwards and downwards - in which security prices are allowed to move within a single day. I examine if the price limits /-8% of the Athens Stock Exchange (ASE) for the bubble period 1998-2001 had an...
