Plugin-development; inserting a static page

Hi.
I am trying to build a plugin.I am trying to insert a static page programmatically when the plugin is installed.
Here is the code:

function dbes_create_events_page()
{
global $wpdb;
$sql= “INSERT INTO wp_posts (post-author,post_title)
VALUES (‘admin’,’Eventi’)”;
$wpdb->query($sql);
}

As you see I just inserted two fields, for a test…
This does not work, I just get error messages…
WHat is the right way to implement this?
Cheers,
Davide
