This time, many countries used the inflows to build up as long as ex reserves, rather than to finance Current Account deficits 2003-07 boom 1991-97 boom Source: Benn Steil, Lessons of the Financial Crisis, CFR, March 2009 The financial crisis was abruptly transmitted to emerging markets in September 2008. What characteristics have helped emerging markets resist financial contagion in the past High FX reserves in addition to /or floating currency Low as long as eign-denominated debt (currency mismatch) Low short-term debt (maturity mis-match) High Foreign Direct Investment Strong initial budget, allowing room to ease. High export/GDP ratio, Sachs (1985); Eaton & Gersovitz (1981), Rose (2002); Calvo, Izquierdo & Talvi (2003); Edwards (AER, 2004); Cavallo & Frankel (JIMF, 2008).

Are big current account deficits dangerous Neoclassical theory – if a country has a low capital/labor ratio or transitory negative shock, a large CAD can be optimal. In practice – Developing countries with big CADs often get into trouble. Traditional rule of thumb: “CAD > approx. 4% GDP” is a danger signal. “Lawson Fallacy” – CAD not dangerous if government budget is balanced, so borrowing goes to finance private sector, rather than BD. Amendment after 1994 Mexico crisis – CAD not dangerous if BD=0 in addition to S is high, so the borrowing goes to finance private I, rather than BD or C. Amendment after 1997 East Asia crisis – CAD not dangerous if BD=0, S is high, in addition to I is well-allocated, so the borrowing goes to finance high-return I, rather than BD or C or empty beach-front condos (Thail in addition to ) & unneeded steel companies (Korea). Amendment after 2008 financial crisis – yes, all CADs are dangerous. Lessons of the 1994-2002 crises Many emerging markets after the 1990s learned to (1) float or hold large reserves or both (2) use capital inflows to finance reserve accumulation (“self-insurance”), rather than current account deficits (3) take capital inflows more in the as long as m of FDI or local-currency-denominated debt flows; avoiding the currency mismatch of $ liabilities in addition to avoiding short-term bank loans. The ratio of reserves to short-term debt is the most robust predictor of crisis likelihood & severity. e.g. the Guidotti Rule: Keep ratio >1 Early Warning Indicators: Some references on statistical predictors of crises among developing countries Jeffrey Sachs, Aaron Tornell & Andres Velasco, “Financial Crises in Emerging Markets: The Lessons from 1995” (1996): Combination of weak fundamentals (changes RER or credit/GDP) in addition to low reserves (relative to M2) made countries vulnerable to tequila contagion. J. Frankel & Andrew Rose, “Currency Crashes in Emerging Markets” (1996): Composition of capital inflow matters (more than the total): short-term bank debt raises the probability of crash; FDI & reserves lower the probability. Graciela Kaminsky, Saul Lizondo & Carmen Reinhart, “Leading Indicators of Currency Crises” (1998). Best predictors: Real ex. rate, M2/Res, GDP, equity prices. A.Berg, E. Borensztein, G.M.Milesi-Ferretti, & C.Pattillo, “Anticipating Balance of Payments Crises: The Role of Early Warning Systems,” IMF (1999). The early warning indicators don’t hold up as well out-of-sample.

Did those who obeyed the lessons of 1994-2002 done better in response to the 2008-09 shock Some who had large current account deficits & as long as eign-currency debts did have the most trouble, particularly in Central & E.Europe: Hungary, Ukraine, Latvia Despite views of some economists that emerging market countries had been holding too many reserves, they appear to have turned out the ultimate insurance. Aizenman (2009): “The deleveraging triggered by the crisis implies that countries that hoarded reserves have been reaping the benefits.” Systematic studies are only starting. Obstfeld, Shambaugh & Taylor (2009a, b): Finding: A particular measure of countries’ reserve holdings just be as long as e the current crisis, relative to requirements (M2), predicts 2008 depreciation. Current account balances & short-term debt levels are not statistically significant predictors, once reserve levels are taken into account. Rose & Spiegel (2009a, b) in addition to Blanchard (2009) found no role as long as reserves in predicting who got into trouble. Frankel & Saravelos (May 2010): We get stronger results, because we consider crisis period to have gone thru March 2009. Top 8 categories of Leading Indicators in pre-2008-crisis literature Frankel & Saravelos (2010)

Next 9 categories of Leading Indicators in pre-2008-crisis literature Frankel & Saravelos (2010) Equity prices suggest that the global financial crisis did not begin in earnest until Sept. 2008, nor end until March 2009 – whereas Rose & Spiegel, Obstfeld et al, look simply at 2008

Big emerging markets came of age in 2009 Macroeconomics: decoupling Global governance: the G-20 replaces the G-7 The RMB issue De-coupling turned out to be real after all at least with respect to East Asia, which has rebounded very strongly over the last year, after a sharp loss of exports over the preceding year, from 2008 QI to 2009 Q I. China’s growth has not only returned to its blistering pace of 10% but by now is a source of global growth because China is now a much larger share of the world economy than in the 1980s or 90s. India, Indonesia, & other Asian countries also weathered the global recession well, in addition to are growing strongly. Asian exports were especially hard-hit via RGE Monitor 2009 Global Outlook

Context of the study Lack of longitudinal qualitative research exploring the personal communities of older widows experiencing transition in contemporary Britain (Collins, 2011) I was particularly interested in older women?s personal communities or social networks in addition to if in addition to how they change during widowhood Study design Methodological approach ? qualitative framework, longitudinal design Purposive sample ? 26 older widows, widowed between 1 in addition to 3 years (transitional phase) Method ? series of three in depth interviews conducted over eighteen months, including the use of personal community diagrams so that identify the structure of social networks, in addition to Christmas in addition to Christmas cards so that further explore social relationships in addition to practices Analysis ? thematic analysis of interview transcripts in addition to content analysis of diagrams In depth interviews 1st baseline interviews summer 2004, then 2nd interviews six months later just after Christmas 2005 in addition to then third in addition to final interviews 12 months after 2006 The focus of the 2nd second in addition to 3rd interviews was the shared social event of Christmas, the women were also asked so that save their Christmas cards in addition to talk the researcher through them

In depth interviews The ongoing experiences of the women were also discussed, in addition to their personal community diagrams revisited ? the women were asked so that comment on any changes within their network in addition to so that add members if they wished Personal community diagrams consist of three concentric circles ? inner circle: name people that are very close in addition to important so that you ? middle in addition to outer circles: name people that are less close but still important so that you Benefits of a longitudinal approach The women were willing so that share details of their daily lives alongside me over an extended period of time Being ?alongside? the women as events in their lives unfolded, revealed the positive in addition to negative aspects of continuity in addition to discontinuity during transition (Collins, 2013) Much of the earlier widowhood literature focuses on discontinuity as a negative aspect of change Benefits of a longitudinal approach In addition so that interviewing the women, I have been shown family photographs in addition to invited so that celebrations alongside family in addition to friends

Benefits of a longitudinal approach Ray (2000: 16) refers so that this as ?being privy? so that ?daily intimacies? This led so that a more in-depth understanding or ?insider knowledge? of the women?s personal communities during transition Challenges in addition to difficulties Problematic ethical in addition to methodological issues involved in the longitudinal study of widowhood in later life include: Sensitivity of bereavement Changes observed in relation so that transition may occur due so that the process of ageing Attrition Challenges in addition to difficulties One of the women died in between the first in addition to second interviews, in addition to four of the women were unable so that complete the third interview due so that ill health or in consideration of personal circumstances, in consideration of example, one of the older widows had recently lost her son

Challenges in addition to difficulties Interview transcripts were not returned so that the women due so that the sensitive nature of the material, involving bereavement in addition to family relationships, which may have caused emotional distress so that the women, in addition to also so that their families in the event of their death Strategies in consideration of engaging participants Participants give a lot of time so that longitudinal studies, feedback is essential if people are so that feel their time has been well spent (Tinker, 1998) Sixsmith et al. (2003:587) stress ?the importance of maintaining access, trust, in addition to credibility? by sharing knowledge alongside participants throughout the research process Strategies in consideration of engaging participants I kept in touch alongside Christmas cards,some of the women responded alongside cards, letters in addition to phone calls about their news

Strategies in consideration of engaging participants The women were also sent regular update letters on the research process A final summary report was sent outlining the findings of the study once complete Conclusions As the study utilised personal community diagrams in addition to interviews at more than one point over a period of time it was possible so that identify shifts in personal community type as well as changes in the women?s social relationships in addition to practices Longitudinal research reveals the complex process of transition, including multiple in addition to parallel transitions that unfold over time Further research With older widowers so that explore gender differences, including the characteristics of social relationships in addition to practices, during transition

Respiratory Hazards Dusts Created when solid material are broken down into fine particles that float in the air before settling under gravity. Fumes Created when solid material vaporize under high heat in addition to then condense. EX. Metal vapor cools in addition to condenses into extremely small particles from welding, smelting, in addition to pouring molten metal Vapors condense into small particles that are light enough so that be breathable Respiratory Hazards Mists Tiny liquid drops formed from liquid materials by atomisation in addition to condensation processes Ex. Spraying operations, plating operations, mixing in addition to cleaning operations Gases Substances that are similar so that air in their ability so that diffuse or spread freely throughout a container or air Ex. Oxygen, carbon dioxide, carbon monoxide, nitrogen, in addition to helium Respiratory Hazards Vapors The gaseous state of substances that are either liquids or solids at room temperature. They are formed when solids or liquids evaporate. Ex. Petroleum, paint thinners, degreasing solvents Oxygen Deficiency Occurs when the percentage of oxygen in the air falls below 19.5%. Deficiency can be caused by a chemical reaction, fire, or when other chemicals displace oxygen from the air.
