The criterion can be applied to models with infinite past and future as well as those with a truncated past. The equilibrium is not necessarily a steady state; for example, demographic and type composition of the population or individuals’ endowments can change over time. However, asymptotically, the equilibrium should be stationary. The two limiting stationary paths at either end of the timeline do not have to be the same. If they are, conditions for local uniqueness are far more stringent for an economy with a truncated past as compared to its counterpart with an infinite past. In addition, we illustrate our main result using a textbook model with a single physical good, a two-period life-cycle and a single type of consumer. In this model we show how to calculate a response to a policy change using the implicit function theorem.","PeriodicalId":11757,"journal":{"name":"ERN: Other Microeconomics: General Equilibrium & Disequilibrium Models of Financial Markets (Topic)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85494120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combined shorting cost amounts to almost 40 percent of gross long–short arbitrage raw returns over the sample period from January 2006 to December 2017. After adjustment for these shorting costs, long–short arbitrage profits are thus reduced by almost 40 percent. Even after adjustment for risk, the proportion of shorting costs is also substantial. If other trade-related transaction costs are considered, long–short arbitrage profits would be reduced further. Our results provide explicit evidence that casts doubt on the profitability of long-short arbitrage strategies based on anomalies.","PeriodicalId":11757,"journal":{"name":"ERN: Other Microeconomics: General Equilibrium & Disequilibrium Models of Financial Markets (Topic)","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79300942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An active static equilibrium with strong joint venture formation, large output, and low unemployment can coexist with a passive static equilibrium with low joint venture formation, low output, and high unemployment. Changes in fundamentals move the system between the two static equilibria, generating large and persistent business cycle fluctuations. The volatility of shocks is important for the selection and duration of each static equilibrium. Sufficiently adverse shocks in periods of low macroeconomic volatility trigger severe and protracted downturns. The magnitude of government intervention is critical to foster economic recovery in the passive static equilibrium, while it plays a limited role in the active static equilibrium.","PeriodicalId":11757,"journal":{"name":"ERN: Other Microeconomics: General Equilibrium & Disequilibrium Models of Financial Markets (Topic)","volume":"43 8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87503932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Мы ограничились рассмотрением пяти площадок для интеграции, образование которых, на наш взгляд, наиболее вероятно с учётом стадий переговоров их потенциальных участников: ТТП без США, ШОС, АСЕАН, ВРЭП и ТТИП. Предполагалось что с каждой из этих площадок ЕАЭС может создать или не создавать ЗСТ, что привело нас к рассмотрению 243 различных сценариев. Как показали расчёты, бездействие ЕАЭС имеет, как правило, слабое положительное влияние на страны ЕАЭС как на уровне отраслей, так и на уровне экономики в целом. В тоже время участие стран ЕАЭС в перечисленных интеграционных процессах может давать заметные выигрыши в терминах ВВП (до 1,2% у России) и торговли. Тем не менее, участие в этих процессах создаёт заметные отраслевые риски (спад выпуска до 1,9%) в ряде секторов. \u0000 \u0000English Abstract: Assessment of risks and benefits for the Russian economy from various integration strategies in modern conditions To find the best ways for Russia to liberalize trade between EAEU and other countries of the world, taking into account the hostile actions of third parties (the sanctions confrontation with the EU and the USA, etc.), we used the GLOBE v1 computable general equilibrium model. We have limited ourselves to considering five integration sites, the formation of which, in our opinion, is most likely due to the current state of their negotiation progress: TPP without the USA, SCO, ASEAN, RCEP and TTIP. It was assumed that with each of these sites the EAEU may or may not create an FTA, which led us to consider 243 different scenarios. As shown by the calculations, the inaction of the EAEU has, as a rule, a weak positive effect on the countries of the EAEU both at the level of industries and at the level of the economy as a whole. At the same time, the participation of the EAEU countries in the integration processes can give noticeable gains in terms of GDP (up to 1.2% from Russia) and trade. Nevertheless, participation in these processes creates noticeable industry risks (decline in output to 1.9%) in some sectors.","PeriodicalId":11757,"journal":{"name":"ERN: Other Microeconomics: General Equilibrium & Disequilibrium Models of Financial Markets (Topic)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83350498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I find that such biases create a separation between individual and group level survival: even when the survival probability of a single irrational agent tends to zero, these agents may still succeed as a whole. Effectively the irrational agent population can survive due to a vanishingly small group of increasingly rich agents. Disagreement over idiosyncratic uncertainties distorts savings decisions and interest rates, but idiosyncratic risks are not priced. Simulations confirm that the limiting results are relevant when the population of irrational agents is large.","PeriodicalId":11757,"journal":{"name":"ERN: Other Microeconomics: General Equilibrium & Disequilibrium Models of Financial Markets (Topic)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80897222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The correlations between the upstream exposure and equity return networks are large and statistically significant, while the downstream exposure networks have lower — but still positive — correlations that are not statistically significant. These results suggest a low short-term elasticity of substitution across inputs transmitting shocks from suppliers, but more flexible ties with downstream firms. Additionally, both the DSGE model and simulations of our empirical approach highlight the importance of accounting for common factors in network estimation, which become more important over our 1989-2017 sample period, explaining 11.7% of equity return variation over the first ten years and 35.0% over the final ten.","PeriodicalId":11757,"journal":{"name":"ERN: Other Microeconomics: General Equilibrium & Disequilibrium Models of Financial Markets (Topic)","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77427928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that bargaining delays arise when investors have precise private information about the asset quality, but the public information (e.g. credit ratings, benchmarks, past quotes) is coarse. We incorporate this type of bargaining delays into the standard dynamic equilibrium model of over-the-counter markets with search delays a la Duffie, Garleanu and Pedersen (2005) and derive implications of both delays for prices and liquidity. Search and bargaining delays have opposite effects on the range of traded assets showing that the current approach that views search delays as a proxy for all types of delays is with a loss. Conditional on the public information, the liquidity is U-shaped in the quality and assets in the middle of the quality range may not be traded, which contrasts with the descreasing liquidity in asymmetric-information models.","PeriodicalId":11757,"journal":{"name":"ERN: Other Microeconomics: General Equilibrium & Disequilibrium Models of Financial Markets (Topic)","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74041851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposal features a unanimous agreement of the national citizenries of the world and global Pareto efficiency. We run a simulation in the spirit of the Paris Agreement, with zero emissions after 2055. At the Global Unanimity Equilibrium, permits are priced at 90$/tC, yielding 1.3 trillion dollars annually.

With countercyclical risk aversion (RA), a positive shock to uncertainty increases risk and elevates RA as consumption growth falls. The combination of high RA and high uncertainty produces significant equity risk premia in bad times, which in turn, exacerbate the decline of macroeconomic aggregates and equity prices. Moreover, in the cross-section of equity returns, investors demand a risk premium for stocks that perform poorly in times of high uncertainty and elevated risk aversion. In a model with endogenously time-varying RA, uncertainty shocks lead to large falls in investment and equity prices that closely match state-dependent data responses.
