1. Introduction
Previous studies have found that firms with political connections receive preferential treatment to finance, enjoy lower debt and equity costs, and have more procurement contracts (
Claessens et al. 2008;
Boubakri et al. 2012;
Houston et al. 2014;
Goldman et al. 2013;
Harymawan 2018). Other studies have shown, however, that connected firms pay higher audit fees to auditors and charge higher prices for debt to debtholders as a cost of political connections (
Bliss and Gul 2012;
Gul 2006).
Grier et al. (
1994) have also examined the benefit–cost model across industries and the contributions of political action committees in each industry, finding that industries with higher potential benefits from government connections contribute more to their connections.
This study extends these prior findings in the political connections literature by investigating the effect of political connections on firms’ stock price crash risk. Recent studies have provided evidence that establishing political connections (i.e., hiring a politician as a director) can decrease the firm’s stock price crash risk (
Luo et al. 2016;
Hu and Wang 2018). In contrast,
Lee and Wang (
2017) and
Tee (
2018) have shown that connected firms tend to have a higher stock price crash risk. Meanwhile,
Roberts (
1990) found a relationship between committee seniority in the US Congress and the distribution of federal benefits. He also found that the stock market reacted significantly to the death of Senator Henry Jackson, especially across his various constituent interests. Using the unexpected resignation of former Indonesian President, Suharto, this study was able to investigate the stock price crash risk of connected firms in the period before and after his resignation. This unique event provides a better setting than a simple relationship model for answering the question of whether connected firms have a higher or lower stock price crash risk than unconnected firms.
Investigating the relationship between political connections and stock price crash risk in the pre- and post-Suharto era provides us with a better research setting for several reasons. First, as
Fisman (
2001) shows, during the Suharto era, political connections in Indonesia were centralized, which provides a better proxy than a decentralized country for evaluating political connections; measuring the value of political connections in a country with decentralized political decision-making is more complex due to the variety of connection types. Second, the unexpected resignation of Suharto is an exogenous event which allows us to make clearer estimates when evaluating the relationship between political connections and stock price crash risk.
In this study, we first employed some univariate tests to describe our data and test the hypotheses. The correlation matrix shows that firms connected to Suharto have a significantly higher stock price crash risk. Then we compared the mean between a group of connected versus non-connected firms. The results also show that firms with Suharto connections had a significantly higher mean of stock price crash risk than firms with no connections.
In the multivariate analyses, we used the ordinary least square regression to test the hypotheses. We found that firms with political connections had a negative and significant association with stock price crash risk. To deal with the endogeneity issue, this study employed the difference-in-difference model, using the unexpected resignation of Suharto as a natural experiment. We found that in the period prior to the Suharto resignation, connected firms were more likely to have a lower stock price crash risk. Interestingly, we found that after Suharto resigned, there was a positive and significant association between political connections and stock price crash risk.
This study contributes to the existing literature of political connections in several ways. Prior studies have examined the relationship between political connections to stock price crash risk (citation). This study adds to this literature by being the first in providing evidence on how political connections affect stock price crash risk by comparing when the political connections are in and out of power. In addition, this study also extends the literature by examining the role of firm complexity on the relationship between political connections and stock price crash risk. For practitioners, this study provides useful information about the changes of stock price crash risk of politically connected firms between pre and post political power. For a regulator, these findings provide an insight that political activities disclosure might help the investor to reduce the information asymmetry between firms and stakeholders to reduce the likelihood of stock price crash risk for politically connected firms in the period post to political power resignation. The remainder of this article discusses the institutional setting of political connections in Indonesia and presents the hypotheses, data, methods, results, discussion, and conclusion.
4. Empirical Analysis
Table 1 presents the sample distribution for the period 1995–1997 and 1999–2001. We excluded the year of Suharto’s resignation (1998) to achieve an unambiguous pre-event and post-event period for the main tests, especially for the difference-in-difference test. Among the 730 firm-year observations, the number of firms with political connections was 149 and those without political connections 581.
Table 2 presents descriptive statistics for the period 1995–1997 and 1999–2001, totaling 730 firm-year observations. All variables are defined in the appendix. The sample mean of
PCON is 0.204, indicating that about 20% of the sample was connected politically to Suharto and the remaining 80% was not. The dependent variables (
CRASH,
DUVOL, and
NCSKEW) and variable of interest (
PCON) are presented in current-year values. The control variables are presented in lag-one-year values because lag-one-year values of these variables are used in the regression model.
Table 3 presents the Pearson correlations. It displays the correlations between dependent variables, the independent variable, and the control variables. The significance level is denoted at 10%, 5%, and 1%.
Table 4 presents the characteristics of politically connected and non-politically connected firms. We observed that firms with political connections are in general larger in terms of total assets than those without political connections. These politically connected firms also have higher leverage.
Table 5 presents the regression results for the relationship between political connection and stock price crash risk. The coefficient of political connection (
PCON) was negative and significant for all three risk models (
CRASH and
DUVOL at the 1% level and
NCSKEW at the 5% level) after controlling the firm-specific control variables. This result was consistent with our prediction, which is that the stock price crash risk is lower for politically connected firms. Therefore, hypothesis 1 is supported.
To use the difference-in-difference model, we needed to test whether the parallel trend assumption holds. The visual inspection method was not appropriate for this study because the main dependent variable (stock crash) is an indicator variable. Therefore, we conducted a formal test on the parallel trend. Our sample contained three pre-treatment periods and three post-treatment periods. Following
Autor (
2003), we specify the following model:
where
Y is the outcome for firm
i at time
t. We included the interactions of the time dummies and the political connection indicator for the first two pre-Suharto-resignation periods and dropped the one for the year of Suharto’s resignation. Therefore, all the other interactions are shown with reference to this omitted period. If the coefficients
B−2 and
B−1 were not significant, then the difference in differences was not significantly different between the politically connected firms and non-politically connected firms in the pre-Suharto-resignation periods, indicating that the parallel trend assumption holds.
As we included all the Suharto-connected firms as a treatment group and all the non-Suharto-connected firms as a control group during the sample period, the random sampling assumption for the treatment group and control group was not a concern in our study.
Table 6, panel A presents regression results testing the parallel trend. The coefficients for
PCON1996 and
PCON1997 were insignificant, indicating that the parallel trend assumption holds. Besides, it can be observed from the coefficients for
PCON1999,
PCON2000, and
PCON2001 that the increased stock crash risk for Suharto-connected firms fades across the years in the post-Suharto period.
Table 6, panel B presents the regression results for the effect of the fall of Suharto on the relationship between political connection and stock price crash risk. The coefficient for differences in differences (
DID) is positive and significant at the 1% level for all three risk models after controlling the firm-specific control variables and country-level control variables. This result is consistent with our prediction, which is that the stock price crash risk of politically connected firms increased after the fall of Suharto. Therefore, hypothesis 2 is supported.
Table 7 reports the results of the sensitivity test for
Table 5 on the regression of stock price crash risk on political connection because this test includes the year in which Suharto resigned, 1998. The coefficient of political connection (
PCON) for all three models was negative (
CRASH at the 1% level, and
NCSKEW at the 10% level), indicating that political connection lowers stock price crash risk. The significance level for
NCSKEW and
DUVOL in
Table 7 was lower than in
Table 5. This is because the inclusion of observations for 1998, the year in which Suharto resigned, may have introduced some noise into the regression model.
Table 8 reports the results of the sensitivity test for
Table 5 on the regression of stock price crash risk on
DID because this test includes the year in which Suharto resigned, 1998. The coefficient of
DID for all three models was significantly positive, indicating that the stock price crash risk of politically connected firms increased after the fall of Suharto.
To investigate whether a political connection exerts distinct impacts on stock price crash risk when interacting with the differential complexity of firm structure (H3), the full sample was divided into two subsamples according to the complexity of firm structure.
Table 9 presents the regression results for the effect of complexity of firm structure on the relationship between political connection and stock price crash risk. The coefficient for political connection (
PCON) was negative and significant at the 1% level for all three risk models for complex firms after controlling the firm-specific control variables. This result was consistent with our prediction, which is that the negative relationship between political connection and stock price crash risk is more pronounced for firms with complex firm structures. Therefore, hypothesis 3 is supported. In addition, we also tested (non-tabulated results) whether the negative associations between political connection and stock price crash risk in complex firms are due to the size effect (
Dang et al. 2018). Hence, we run similar regression model except we exclude the
SIZE variable. We find that the coefficients of
PCON are still negative.
To ensure that the assignment of observations into the treatment group and control group was random, we adopted the coarsened exact matching (CEM) method. We set each covariate into five equal bins, or strata. Eight covariates were input into the CEM model.
Table 10, panel A presents the matching CEM summary. Out of a total of 171 strata generated by the CEM model, 36 strata contained both connected and unconnected observations. A total of 109 out of 149 connected observations were matched with 403 out of 581 unconnected observations.
We used L1 statistics to measure the matching quality (
Iacus et al. 2012;
He et al. 2019). L1 statistics are the absolute difference in the value of covariates between the connected and unconnected firms.
Table 10, panel B presents the diagnosis of the matching quality of the CEM method. The results show that the post-match L1 statistics were generally lower than the pre-match L1 statistics, indicating there is a significant improvement in the matching quality with CEM.
Table 10, panel C presents the result of the replication of the baseline model with the difference-in-difference model by the CEM method. The table reveals a consistent result with that in
Table 6 Panel B, further supporting our hypothesis.
