About 80% of corporate executives in Thailand have no confidence their economy will improve in 2014.
The survey by the British consulting firm Grant Thornton found that only 2% of respondents expect rising profits in the coming 12 months.
Only 4% said they plan to invest more in plant or machinery, compared with 18% the previous quarter.
Executives anticipate political and economic instability after the Constitutional Court ruled against charter amendments that might have allowed former prime minister Thaksin Shinawatra, brother of current prime minister Yingluck Shinawatra, to return from self-imposed exile.
