But, in times of financial turmoil, the growing use of sophisticated risk management techniques by financial intermediaries might have the paradoxical effect of amplifying the initial shock, exhausting liquidity and contributing to contagion phenomena. Regardless of the intrinsic qualities of these risk management tools, we see that their growing use in the same fashion by all market participants may have produced pernicious effects. When market players rely on converging risk evaluations, they tend to take the same decisions at the same time, thus amplifying initial shock to prices and trading volumes. Financial techniques can also reinforce the links between the various market segments. A striking feature of recent developments on financial markets is the quick spreading of disryptions from one market segment to another, especially between equity and credit markets. For example, the short selling of equities is sometimes used to hedge credit risk. The underlying reasoning is that if there is a credit default, the value of the equity will decrease symmetrically, and an equity gain will compensate the lender for the credit loss. As a result, the fall in the equity value, which is triggered by the credit default, is amplified by the short selling operation. Credit risk derivatives constitute another financial innovation which has played an increasingly important role in the last years. It has contributed to avoiding credit institutions to be heavily impacted by the large credit defaults that have occured recently. Credit risk derivatives have also enabled banks to fine-tune the risk-return profile of their loan portfolios.

Job growth has been particularly strong at retailers, hotels and restaurants, and also service firms ranging from advertising to engineering. That said, the employment picture does have some difficulties. For example, there is concern over some well-paying health sector jobs given the financial strain at Long Island College Hospital and Interfaith Medical Center and the pressure to close those institutions. Brooklyn’s economic vitality is also reflected in the commercial real estate market, as both office and retail vacancy rates have fallen steadily over the past few years. In fact, office vacancy rates are now lower in Brooklyn than in Manhattan. The strength in the housing market is also evident, with the median home price up by roughly 10 percent in each of the past two years, and the rental market has shown similar strength. 2  BIS central bankers’ speeches  However, these increasing prices also raise two other issues that acutely afflict many in Brooklyn and New York City more broadly: housing affordability and poverty. Despite Brooklyn’s economic renaissance and growing affluence, a large swath of the Borough’s population – one in four residents – still lives in poverty, and many struggle to pay their rent or mortgage. Even with the strong pace of job creation, Brooklyn’s unemployment rate has remained high, averaging more than 9 percent in 2013.
