Abstract
A secure business environment for private enterprises is desired by all states and is endorsed as a part of United Nation’s sustainable development goals. However, the risk exposure of private enterprises against terrorism, particularly in developing countries, is not adequately studied. Using Enterprise Surveys (ES) data for more than 2000 firms located across the four provinces of Pakistan, this paper studies the link between the risk of terrorism and firm performance. It finds, after controlling for various firm specific performance determinants as well as provincial and sector specific heterogeneities, that terrorism has a significant negative effect on firms’ performance which is independent of firm size. This effect is robust against different specifications and estimation methods including instrumental variables strategy. Beyond much explored aggregate consequences, terrorism has direct consequences for production processes at micro level.

A Appendix I Tables
Variable definition and sources.
Terror(log) | Log of successful terrorist incidents in a given year in a given province. In GTD, a successful terrorist incidents is defined in terms of its tangible effects. (See page 24, GTD Codebook, 2016). | GTD (2016) |
TerrorIndex(log) | Log of terrorism index. The index constructed as a weighted average of number of terrorist attacks in a year, number of people killed and injured in an attack. The weights assigned are those used by Global Terrorism Index (2016) i. e. a weight of 1 is given to number of terrorist incidents, a weight of 3 to number of people killed in an incident, and a weight of 0.5 to number wounded. | GTD (2016) |
PViolence(log) | Log of the number of violent incidents in a given year. This variable considers only successful incidents and ignores all others. The incident is defined as successful if the attacker(s) hit their intended target. | BFRS data. Bueno de Mesquita et al. (2015). |
Growth(%) | Annual percentage change in Gross Provincial Product. | State Bank of Pakistan Hand Book of Statistics on Pakistan’s Economy2 |
CurrentExp(%) | Annual percentage share of current expenditures in Gross Provincial Product. | State Bank of Pakistan Hand Book of Statistics on Pakistan’s Economy |
Age(years) | Age of a firm in years. | ES data |
StateOwnership(%) | Proportion of state/government ownership in a firm (measured in percentage). | ES data |
ExporterD | Binary variable assumes a value of 1 if a firm directly exports at least 10 % of its sales | ES data |
IntQaulityCert | Binary variable, assumes a value of 1 if a firm has an internationally recognized quality certification e. g. ISO9000, 9002, or 14,000 | ES data |
InternalFin(%) | Proportion of working capital financed by internal funds (measured in percent). | ES data |
LaborRegConst | Binary variable, assumes a value of 1 if a firm identifies labor regulations as a major constraint | ES data |
ElectricLoss(%Sales) | Loss due to electrical outages as a percentage of annual sales. | ES data |
AnnualSalesGr(%) | Real annual sales growth (in percent). The annualized sales in a given fiscal year t for a firm i are calculated using the following formula: | ES data |
CorruptionD | Binary variable, assumes a value of 1 if a firm identifies corruption as a major constraint. | ES data |
SecurityCost(%Sales) | Security costs (percentage of annual sales). | ES data |
FirmSizeD | Binary variable assuming a value of 1 if the number of workers is more than 1001. | ES data |
SMED | Binary variable assuming a value of 1 if the firm is identified as either small or medium sized. | ES data |

In column (4) the sectorial effects are controlled for following major sectors in the sample of firms used in this study: Chemicals; machinery and electronics; motor vehicles and transport; non-metallic mineral products; services; garments and textiles. The original ES survey data provide 11 sector categories. The classification here merge categories related to garments, textiles, and services to avoid multicollinearity and also to make distinctions sharper across sectors.

Columns (1) and (2) report the results of two stage GMM instrumental variable regression. In model (1) Terror(log) is instrumented using (i) number of perpetrators, (ii) and the number of terrorists killed in an incident. In model (2) the instruments are (i) number of terrorists killed, (ii) and number of terrorists wounded in an incident. Information on instruments is extracted from Global Terrorism Database (GTD 2016).
Interaction models in columns (3) and (4) report marginal effects. Terrorism is interacted with SMED and Manufacturing, respectively, in columns (3) and (4). Dependent variable in all models is EmpGr%.
