摘要
Korean Abstract:本论文通过住宅价格渠道分析了住宅价格如何影响宏观经济变数。作为分析方法,将Iacoviello(2005)的经济结构和动态概率性一般均衡(DSGE)模型应用于韩国数据。根据本论文的分析结果,住宅和消费之间的互补性越强,消费对住宅价格上涨的反应就越大,出现住宅和消费之间的同步现象。如果补充性为0.42,LTV(住宅担保贷款)为50%,住宅价格上升1%,消费将上升0.057%p;如果补充性为0.52,住宅价格上升1%,消费将上升0.047%。另一方面,房价与宏观经济变数挂钩的主要渠道是消费的变化。如果房价上涨,消费就会增加,这又会对整个宏观经济产生影响。另一方面,住宅和消费之间的替代弹性被推定为0.42,确认了住宅和消费之间存在补充性。这一补充性起到了扩大住宅价格对消费影响的重要作用。english abstract:This paper investigates the manner in which house prices affect macroeconomic variables through a house price channel by applying the method of Iacoviello (2005) to Korean dataand establishing a DSGE model with complementarity。This paper found that higher LTV ratio coupled with stronger complementarity results in the co-movement in the both consumption and housing。For instance, the results show that when the LTV ratio and complementarity stands respectively at 50% and 0.42 an 1% rise in house prices increases consumption by 0.057%;and when the complementarity parameter increases to 0.52 with LTV remains unchanged at 50%, consumption rises by 0.047% per 1% increase in house prices。An increase in house prices leads credit constraints for borrowers to become more loose as value of a house rises as a collateral。The increase in household credit enables more consumer spending, eventually leading to increased consumption。A key link in which house prices are connected to macroeconomic variables is change in consumption。To put it simply, a rise in house prices leads To an increase in consumption, which consequently impacts the overall macro-economy。At this point, complementarity is found, in that the elasticity of intra-temporal substitution between housing and consumption is estimated At 0.42;which plays an important role in the house price channel by amplifying the effects of house prices on consumption。
