Abstract
To promote export diversification, the Tunisian government is implementing a $22 million export matching-grant scheme, TASDIR+. TASDIR+ aims to increase exports and promote export diversification toward higher value-added exports and new markets. This study is using a randomized controlled trial to evaluate TASDIR+’s traditional matching grant scheme and a newly implemented rebate scheme. Under the traditional matching grant scheme, eligible firms receive a 50% cost subsidy for eligible export-related expenses. Under the rebate scheme, available to agriculture/agribusiness firms, eligible firms receive the 50% cost subsidy and a rebate based on the firm’s export performance in new markets.

The questions the project seeks to answer are: (i) does subsidizing a firm’s export business plan or office abroad help firms export to new markets or export new product variety? and (ii) do export rebates encourage firms to increase export volume, export new product varieties, and/or export to new (advanced) markets? While both export subsidies and matching grants are popular policy tools, to date there is very little rigorous evidence on their effectiveness, a gap this proposed impact evaluation aims to address.

Experimental Details
Interventions
Intervention(s)
(1) Traditional matching grant scheme: eligible firms receive a 50% cost subsidy for eligible export-related expenses (geared towards general export activity or implantation abroad).
(2) Rebate scheme: eligible firms receive the 50% cost subsidy and a rebate based on the firm’s export performance in new markets.

Firms with agribusiness/agricultural activity are eligible for the rebate scheme. The rebate is given in the form of reimbursement of eligible expenses. The total reimbursement (matching grant + rebate) cannot exceed 90% of the firm’s expenses.
For the rebate, a new market is a market to which the firm did not export an agricultural product in the calendar year prior to application.

Secondary Outcomes (explanation)
Experimental Design
Experimental Design
Firms can apply to the program once, in any of the four scheduled application rounds. Firms self-select into one of the two business plan options: export business plan or internationalization business plan. Eligible firms are identified through a screening process of the applications based on firm characteristics and export destinations. All eligible firms are surveyed online or in person if necessary, and follow-up surveys take place a year later. Stratification is based on three dimensions: the firm's business plan, sector, and size (as determined by mean revenue adjusted for inflation), following which the firms are randomized into treatment and control groups.
