Sequential exporting

► A model based on experimentation rationalizes new stylized facts in firms' export dynamics. ► The model posits that a firm's export profitability is correlated across destinations. ► Conditional on survival, fledgling exporters grow fastest at intensive and extensive margins. ► A firm is more likely to abandon a new export market if this is the firm's first export destination. ► We find strong support for our theoretical predictions using Argentina's customs data.
