This research sought to find local evidence within the Israeli context that corporate social responsibility can have positive impact on corporate financial performance, similar to research findings in leading western economies. Such local based evidence, if found, would encourage the inclusion of CSR as part of strategic management of companies in Israel. The investigation focused on a sample of leading companies in Israel, forming part of the TA-100 stock exchange index, and was undertaken between 2005 and 2006. The research used quantitative investigation of secondary data on financial performance that is available for companies traded on the stock exchange. It included social responsibility ranking undertaken by the association of 'Business for social responsibility in Israel' – MAALA. This data was used to compare financial performance between groups of companies with different levels of social responsibility. The research found that higher social responsibility for companies in Israel was associated with higher financial performance, in comparison to their counterpart companies ranked as lower in social responsibility. However at the extreme, a very high level of social responsibility is associated with decline in financial performance. The research conclusion was that companies in Israel face the same CSR-to-CFP relationship, as their counterparts in leading western economies. This provides the rationale for Israeli companies to incorporate social responsibility as part of their business strategy aimed at improving financial performance
