1 Information and Communication Technologies and Small and Medium Enterprises (SMEs) Performance in Costa Rica: A Randomized Controlled Experiment Research Proposal Presented by Fundación CAATEC * to the Inter-American Development Bank in response to the Call for Research Proposals Information and Communication Technologies (ICT) and Societal Empowerment February 23, 2009 * The Costa Rican High Technology Advisory Commission (Fundación CAATEC) is a private, independent, impartial, non-profit, apolitical, and non-governmental organization that seeks to promote the economic development of the Central American and Caribbean region through the design and promotion of innovation and technology development policies.
2 Background Policy makers and development practitioners acknowledge the leading of Information and Communication Technologies (ICTs) for development. For instance, the Millenium Development Goal (MDG) 8 aims at making available the potential benefits of new technologies (and ICTs in particular) for poor regions of the world. Entrepreneurship and business development provide an option for tackling poverty through the creation of employment and income. In developing countries, SMEs represent an important driver of employment creation and income generation for many low income households. Information and Communication Technologies (ICTs) can create new opportunities for SMEs operational strengthening and business growth. The impact of ICTs on development would depend significantly on how those technologies are accessible to firms, particularly SMEs. CAATEC researchers have conducted several studies to analyze the role ICTs on SMEs performance and the impact of targeted SMEs financing programs on business growth. 1 For instance, Monge-González et al (2005) evaluate the importance of ICTs in the improvement of productivity and competitiveness of SMEs in Central American countries (Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua). The authors conclude that internal factors that favor the adoption of ICTs in SMEs include the use of computers and the Internet by most employees, the existence of a budget to purchase and maintain computers and Internet services, a focus on scientific activities associated to business activities (such as increased levels of knowledge about modern software and advantages of using Internet services), and the willingness to venture into e-commerce. 1 A report of activities from CAATEC ( ) is attached to this research proposal.
3 The main finding of the study was that penetration of the use of ICTs by SMEs in their business process was very low. For the case of Costa Rica, using econometric techniques, Monge-González et al (2007) found that BN-Desarrollo (a microfinance program at Banco Nacional, the country s largest bank) has positively impacted SMEs since year Among other results, an important share of surveyed companies indicates that broader access to credit has improved their business and helped them increase their sales. Moreover, the quantitative analysis suggests a positive impact of access to credit through BN-Desarrollo and SMEs productivity. In addition, employment has increased within the program affiliated firms, with a direct impact on community development. 3 An interesting result from Monge-González et al (2007) study is that only 16 percent of BN-Desarrollo affiliates use Internet Banking (IB) services. This outcome could be partly explained by the fact that SMEs have a limited access to ICTs (Monge-González et al, 2005). But 90 percent of BN-Desarrollo customers that have access to Internet make use of IB tools. Besides, Banco Nacional has a consolidated IB program, with a majority of personal (household) and medium and large firms users. A question that arises is whether the limited access from SMEs to IB tools is the result mainly from limited Internet services or the outcome of other factors. Another key issue is how IB tools are impacting SMEs performance. The answer to both questions would contribute to a better understanding on how specific ICTs in the financial sector could be developed and 2 According to official figures, 70% of total credit for SMEs granted by formal (regulated) financial intermediaries in Costa Rica is allocated through BN-Desarrollo. The study is based on data from 304 companies, divided in two groups: those affiliated to BN-Desarrollo, and other sub-sample of similar companies (controlled group) that do not have access to a similar credit program. A random sample was constructed with several control criteria to avoid selection bias and heterogeneity problems. 3 The impacts on productivity were estimated with Pearson and Spearman correlations, while a hedonic prices model was calibrated to estimate the impact on employee s welfare from BN-Desarrollo affiliated firms.
4 become accessible to more micro and small companies, and what role could they play in business growth and development. Access to business training through ICTs in microfinance programs in Costa Rica is another relevant issue related to SMEs performance. From the perspective of ACORDE (Asociación Costarricense para Organizaciones de Desarrollo, a microfinance NGO), one key complementary component of credit allocation is capacity building (management, marketing, market analysis, etc.). Access to credit is a necessary but not sufficient condition for business growth. Therefore, ACORDE created in year 2004 a business development service department, with a capacity building model that supports financial management. Since then, program evaluations indicate that training courses have impacted SMEs performance significantly. One important conclusion is the need to make capacity building more accessible to a wider group of SMEs, particularly from a regional perspective. 4 A recent program evaluation found that 53% of surveyed SMEs believe that capacity building activities are important for their performance, while 62% of companies require particular business skills strengthening. Limited time (31% of respondents) and lack of interest (18%) are among the most relevant reasons why SMEs do not take advantage of capacity building activities. On the other hand, 80% of ACORDE customers have a computer while 61% use Internet. This evidence suggest that making training programs accessible through the Internet could help to overcome time and distance barriers, and even motivate higher participation (more flexibility). 4 The target of beneficiaries is urban companies, due to limited resources.
5 Based on the previous experiences, the proposed research aims to contribute to a better understanding of key issues related to the adoption of particular ICTs by small companies in developing countries. In this way, the study would give evidence on which policies or strategies could serve the objective of making ICTs an effective business tool to improve SMEs performance, with an impact on sales, profits, employment creation and other development relevant variables. Methodology To achieve the research objective, a Randomized Controlled Trial (RCT) will be conducted in order to estimate the impact of ICTs on SMEs performance. Several studies have evaluated the impact of new financial instruments linked to ICTs on business development (Arbursa, 2001; Monge-González et al, 2007; Mas and Kumar, 2008; Ngatia, 2009). Other studies have focused on the impact on households and firms from particular financial tools, applying RCTs (De Mel at al, 2007; Karlan and Zinman, 2009). This evidence suggests that ICTs can influence the performance of financial organizations, the rate of savings and household income, and SMEs growth. The difference between RCT based studies and previous literature is the possibility to identify what specific instruments or policies can be more effective when pursing financial development through broader access to ICTs in developing countries. A Randomized Controlled Trial (RCT) is a study in which subjects are allocated at random to receive one or several interventions (i.e. preventive treatment, technical training, unemployment subsidy). According to Jadad and Enkin (2007) the objective of an RCT is to measure and compare different events called outcomes that are present or absent after the participants receive the interventions. One of the interventions is regarded
6 as a standard of comparison or control, and the group of participants who receive it is called the control group (which can get no intervention at all ). The other groups are called experimental and receive one or more alternative interventions. Among other attributes, RCTs are seen as more precise analysis tools for development research. Traditional methods of measuring program impact may be subject to serious bias due to omitted variables. The critical objective of impact evaluation is to establish a credible comparison group, and in this regard RCT methodology helps to control for several possible causes, and see whether specific programs or interventions work or not (Dulfo et al, 2008). In addition, experimental research offers the possibility to achieve reliable identifications of program effects in the face of complex and multiple channels of causality, which is crucial for development interventions (Banerjee and Dulfo, 2008). Proposed Experiment For this study, one of two possible experiments will be conducted: 5 a) The impact of Internet Banking (IB) tools on BN-Desarrollo (BND) client firms performance. BND was created in 1999, as the Banco Nacional s SMEs financing program. The program has more than 27,000 clients that account for 25% of total bank lending. The group of clients is diverse, from different productive sectors and country regions. 6 For this experiment, Internet Banking (IB) tools will be randomly offered to a group of existing bank clients (SMEs). Other clients will be randomly chosen to 5 The research team believes that both options are relevant for policy recommendations. The final decision on which experiment to conduct will be taken in coordination with IDB representatives. 6 Further details available at https://www.bncr.fi.cr/portalmipyme
7 not receive access to IB tools. The randomization (within-group) will ensure that the intervened clients (those who get access to IB) are essentially similar to those who do not use IB tools. Firm s performance (in terms of labor productivity) will be monitored over a period of time (9-12 months), to analyze whether IB tools have a causal effect on SMEs performance. 7 b) The impact of e-training tools on ACORDE s client firms performance. ACORDE started its first-floor financing operations in It is a microfinance organization that targets urban region micro and small enterprises (the capital and other big cities of Costa Rica). Currently, more than 600 companies are clients, mainly from the industrial and services sectors. 8 An experiment in which owners or managers from client SMEs will be randomly assigned to take an e-training program (on-line, in-company business capacity building program). Here, randomization will help to identify if training courses offered through the Internet could improve business skills in the experimental group, compared to the firms that do not take part of e-training or any other capacity building activity. A non-randomized comparison can give a false picture of the effect of this tool on business performance, since many different variables influence companies management and business decisions. In this case, an encouragement design will be implemented (the encouragement to be part of the training program will be randomly assigned). Firm s performance (sales) will be monitored over a period of time (9-12 months) to analyze whether e-training tools have a causal effect on SMEs sales. 7 Monge et al (2007) found that many BN-Desarrollo clients use IB tools. The authors estimated a positive impact of BN-Desarrollo on labor productivity. However, the authors did not assess the impact of IB tools, isolated from other BN-Desarrollo services. 8 More information at
8 It is worth mentioning that CAATEC researchers have discussed the prospective study details with board members of both potential implementation partners (Banco Nacional de Costa Rica and ACORDE), and obtained support for the research project. In the case of Banco Nacional, the main motivation is to evaluate whether Internet Banking use has an impact on BN-Desarrollo clients performance. On the other hand, ACORDE general manager expressed their interest to support the research as a pilot project with possible scaling up impacts. In both cases, program evaluations have been elaborated. There is however an interest in making a field experiment in order to identify causality between particular tools and client performance. Banco Nacional and ACORDE representatives expressed their willingness to provide primary information and data bases for sample design. An advantage of data bases availability with detailed information (profiles) from client firms in both cases (BN-Desarrollo and ACORDE) is that power calculations for the experiment are more feasible. 9 Power calculations require a preliminary idea of the mean and the variance of the outcome in the absence of the intervention, after controlling for possible covariates and/or stratification. The best way to obtain those estimates is in general to use previously collected data, ideally from the same country or region (Dulfo et al, 2008). Deaton (2009) argues that heterogeneity treatment is a key requirement for successful experiments. 10 In order to address this issue, both controlled and experimental (intervention) groups will be constructed with the use of implementing partner s data bases, taking into account relevant variables (number of employees, age of business, 9 The power of the experiment design is the probability that, for a given effect size and a given statistical significance level, the hypothesis of zero effect is rejected (Dulfo et al, 2008). 10 The author criticizes what he believes is a common practice among RCTs proponents, not to give all the required importance to heterogeneity (and exogenous effects) issues when constructing an experiment design.
9 access to Internet, productive sector, annual turnover, among others), to create a balanced baseline of both groups (experimental and control). This task is crucial, since the identification and isolation of particular interventions effects (apart from various influential variables) is the main objective. The estimation of the causality between intervention and response variables will depend on the formal setting used, including the relevant control variables. The standard (basic) method is to run a regression including only the constant and an intervention dummy: Where: Y i : Outcome of the intervention T: Binary variable that indicates intervention status β 1 : Difference between the mean of Y i in the experimental and control groups (1) Another standard method is to run the regression with additional control variables obtained from the baseline data to include their main effects (Dulfo et al, 2008): (2) Where: X s: Various controls measured at baseline included in the regression If the interaction between the control variables and the intervention is relevant as well, the results of the experiment could be used to run a regression of the form (Deaton, 2009):
10 (3) Where: X s: Various controls measured at baseline included in the regression (both on their main effects and as interactions with intervention status) Using this regression will depend on the experiment chosen and the final objective of the analysis. Available evaluations results and data particularities would condition the construction of the balanced baseline. In addition, implementing partner s insights will be a key input for the final experiment design.
