The purpose of this study is to examine change of institution in labour market after economic reforms. A dynamic element was introduced in the economy with reforms in an effort to achieve more flexibility in the system. The introduction of flexibility in the labour market led to some displacement of labour and an in formalization of the labour force. On the other hand, reallocation of labour from declining to profitable sectors took place significantly within the organized sector and between the organized and the unorganised sectors. Labour market is different from other markets in role of institution. Institution plays an important role in labour market. At macro level, not only labour laws and trade unions but also subcontracting affect market. The value of subcontracting activity was growing at a faster rate than growth rate of output in organized manufacturing during the 1990s. At micro level, wage of employees depends on recruitment and promotion system and labour management. External and internal labour market institutions are primarily concerned with fairness in the distribution of workload and wages, within the non-market framework of the employment relation. Economic reforms had different impacts on industries and sector. We analyse the organized sector, the unorganised sector, the financial sector, declining sector and subcontracting sector.
